Ebola Disease: Symptoms, Transmission, Treatment and Prevention

Ebola disease is a rare but serious infectious illness caused by a group of viruses known as orthoebolaviruses.

Although Ebola has caused major outbreaks and can be f
atal, our understanding of the disease has advanced considerably. Vaccines and specific treatments are now available for Ebola virus disease caused by Ebola virus, while supportive medical care remains important for people affected by other types of Ebola disease. World Health Organization

Understanding how Ebola actually spreads is also important because misinformation can create unnecessary fear.

Ebola does not spread in the same way as common airborne respiratory infections. Transmission generally requires direct contact with infected blood or other body fluids, contaminated materials, or certain infected animals. CDC

What Is Ebola Disease?

Ebola disease is caused by viruses belonging to the orthoebolavirus group.

Different orthoebolaviruses can cause disease in humans. These include Ebola virus, Sudan virus, Taï Forest virus and Bundibugyo virus. Different viruses can have different available vaccines and treatments. CDC

Ebola was first recognised in 1976 during outbreaks in what are now South Sudan and the Democratic Republic of the Congo. World Health Organization

The 2014–2016 West African outbreak later became the largest Ebola outbreak recorded, particularly affecting Guinea, Liberia and Sierra Leone. WHO | Regional Office for Africa

How Serious Is Ebola?

Ebola can cause severe illness and death, but statements suggesting that almost everybody with Ebola dies are misleading.

WHO reports that case-fatality rates in previous outbreaks have ranged from approximately 25% to 90%, with an average of around 50%. World Health Organization

The outcome can depend on factors including the virus involved, the outbreak, the patient's condition and access to appropriate medical care.

Early supportive treatment can improve the chance of survival. World Health Organization

How Does Ebola Spread?

Ebola does not normally spread simply because you are standing near somebody.

A person can become infected through direct contact, through broken skin or mucous membranes, with the blood or other body fluids of somebody who is ill with or has died from Ebola disease.

Transmission can also occur through objects or surfaces contaminated with infected body fluids. World Health Organization

Examples of potentially infectious body fluids include blood, vomit and faeces.

People caring for someone with Ebola without appropriate infection-control precautions can therefore be at significant risk.

Can Ebola Spread Through the Air?

Ebola does not spread like influenza or COVID-19.

CDC states that you cannot contract Ebola simply from being near someone or passing them in a public place. CDC

This distinction is important because fear during an outbreak can lead to misinformation and unnecessary stigma.

Close or direct contact with infectious body fluids is the major concern.

Can Someone Spread Ebola Before Symptoms Begin?

According to WHO, people infected with Ebola cannot transmit the disease before they develop symptoms. World Health Organization

This is another important difference between Ebola and some other infectious diseases.

Once someone becomes ill, however, appropriate isolation, infection-control measures and medical assessment become extremely important.

Can Ebola Spread From Animals to Humans?

Yes.

Scientists believe fruit bats are involved in the ecology and transmission of orthoebolaviruses.

Human infection can occur through contact with the blood, secretions, organs or other bodily fluids of infected animals.

Animals implicated in transmission have included infected fruit bats and non-human primates. World Health Organization

Avoiding contact with sick or dead wild animals is therefore an important precaution in areas affected by Ebola outbreaks.

How Long Does It Take Ebola Symptoms to Appear?

The incubation period—the time between infection and the appearance of symptoms—can range from 2 to 21 days.

On average, symptoms commonly begin around 8–10 days after exposure. CDC

Someone who may have been exposed should follow instructions from the relevant public-health authorities regarding monitoring and medical assessment.

Early Symptoms of Ebola

Ebola can initially resemble several other infectious illnesses.

Early symptoms can include:

fever,
fatigue or weakness,
muscle and joint aches,
headache,
sore throat, and
loss of appetite.

These symptoms alone do not mean somebody has Ebola.

Malaria, typhoid fever and several other infections can produce similar symptoms, which is one reason laboratory testing and appropriate medical assessment are important. CDC

Later Symptoms

As the disease progresses, symptoms can include:

nausea,
vomiting,
diarrhoea,
abdominal pain,
rash,
confusion, and
in some patients, unexplained bleeding.

One misconception about Ebola is that everybody with the disease develops severe bleeding.

That is not the case. CDC and WHO both note that bleeding can occur, particularly later in the disease, but it is not present in every patient. CDC

How Is Ebola Diagnosed?

Symptoms alone cannot reliably diagnose Ebola.

Healthcare professionals use laboratory testing to confirm infection. WHO identifies methods including reverse-transcriptase polymerase chain reaction (RT-PCR) testing and other specialised laboratory techniques. World Health Organization

Because patient samples can present a serious biological hazard, testing requires appropriate infection-control and laboratory procedures.

A person should never attempt to diagnose Ebola themselves based solely on symptoms found online.

Is There Treatment for Ebola?

Yes—but treatment depends partly on the particular virus involved.

Early supportive care is extremely important. This can include fluids and electrolytes, treatment of symptoms and management of complications or other infections. World Health Organization

For Ebola virus disease caused by Ebola virus, WHO recommends specific monoclonal-antibody treatments. World Health Organization

However, approved specific treatments are not available for every type of orthoebolavirus disease.

This is why the old statement that “there is no treatment for Ebola” should no longer be repeated.

Is There an Ebola Vaccine?

Yes, vaccines exist against Ebola virus disease caused by Ebola virus.

WHO currently identifies the Ervebo vaccine as licensed and WHO-prequalified for prevention of Ebola virus disease caused by Ebola virus. It is used particularly as part of outbreak responses. World Health Organization

However, one Ebola vaccine should not be assumed to protect against every orthoebolavirus.

For example, WHO states that there are currently no licensed vaccines for several other Ebola diseases, although vaccine candidates are being developed. World Health Organization

How Can Ebola Transmission Be Prevented?

Ebola prevention during an outbreak requires coordinated public-health measures rather than relying on a single precaution.

WHO identifies important measures including:

appropriate clinical care,
surveillance,
contact tracing,
laboratory services,
infection prevention and control,
safe and dignified burial practices,
vaccination when appropriate, and
community engagement. World Health Organization

Individuals in affected areas should follow instructions issued by recognised health authorities.

People should avoid direct contact with the blood and body fluids of somebody who is sick with suspected or confirmed Ebola unless appropriately trained and equipped to provide care.

Why Safe Burial Practices Matter

A person who has died from Ebola can remain infectious.

Traditional funeral practices involving washing, touching or kissing the body have contributed to transmission during previous outbreaks. World Health Organization

Safe and dignified burial procedures carried out by trained teams are therefore an important part of outbreak control.

This does not mean communities' cultural and religious practices should simply be ignored. WHO emphasises community engagement as an important component of successful outbreak control. World Health Organization

What Should You Do After Possible Exposure?

Having fever or diarrhoea by itself does not mean you have Ebola.

Risk depends heavily on whether there has been a relevant exposure, particularly contact with an infected person's body fluids or another recognised source of infection.

If you believe you have been exposed during an Ebola outbreak, follow instructions from local public-health authorities.

CDC advises people who believe they were exposed and subsequently develop symptoms to contact appropriate healthcare or public-health services immediately. CDC

Where possible, contact the healthcare service before arriving so appropriate infection-control arrangements can be made.

Ebola: The Key Facts to Remember

Ebola is a serious disease, but accurate information helps prevent unnecessary fear.

Remember:

Ebola does not spread like flu or COVID-19.
People do not transmit Ebola before symptoms develop.
Direct contact with infectious body fluids is an important route of transmission.
Symptoms may appear 2–21 days after exposure.
Bleeding does not occur in every Ebola patient.
Early medical care can improve survival.
Specific treatments and vaccines now exist for Ebola virus disease caused by Ebola virus, although they are not available for every type of Ebola disease.
Outbreak control requires professional healthcare and coordinated public-health measures. World Health Organization

Health information about Ebola can change during an outbreak, so current advice from WHO, national public-health authorities and other recognised health agencies should take priority over older information found online.

Are Apples Good for You? Nutrition, Benefits and Healthy Ways to Eat Them

Apples are one of the most familiar fruits, but their everyday availability can make them easy to overlook.

So, are apples actually good for you?

Yes. Apples can be a nutritious part of a healthy, balanced diet. They provide dietary fibre along with vitamins, minerals and naturally occurring plant compounds.

However, apples are not miracle foods. Eating an apple cannot guarantee protection against cancer, heart disease, diabetes or other medical conditions.

The more useful way to think about apples is as one of the many fruits and vegetables that can contribute to a varied and balanced diet.

What Nutrients Are Found in Apples?

Apples contain carbohydrates, dietary fibre and small amounts of various vitamins and minerals.

Like other fruits and vegetables, they can contribute to your overall intake of fibre and micronutrients.

The NHS recommends eating at least five portions of a variety of fruit and vegetables each day. One medium-sized apple counts as one adult portion of your 5 A Day. nhs.uk

The word variety is important.

Eating several apples does not mean you should neglect vegetables and other fruits. Different plant foods provide different combinations of nutrients, so apples are best viewed as one part of a varied diet.

1. Apples Can Help You Get More Fibre

One advantage of eating whole apples is their fibre content.

Dietary fibre is an important component of a balanced diet. The NHS notes that fruit and vegetables are good sources of fibre and that fibre helps support digestive health. nhs.uk

Eating the apple with its edible skin can retain more of the whole fruit than peeling it.

Wash fresh apples before eating them, particularly when you intend to eat the skin.

Rather than depending on apples alone for fibre, include a range of fibre-containing foods such as vegetables, other fruits, beans, pulses and wholegrain foods.

2. Apples Count Towards Your 5 A Day

An easy benefit of eating an apple is that it can contribute towards your daily fruit and vegetable intake.

For adults, the NHS considers one medium apple to be one portion of the recommended 5 A Day. nhs.uk

The recommendation is to eat at least five portions of a variety of fruits and vegetables each day, rather than five portions of the same food.

An apple can therefore be combined with foods such as berries, oranges, leafy vegetables, tomatoes, carrots, peppers and other fruits and vegetables you enjoy.

3. Whole Apples Can Be a Convenient Snack

Apples require very little preparation.

They can be carried to work, included in a packed lunch or eaten at home without cooking.

Choosing whole fruit can also be preferable to relying heavily on fruit juice.

The NHS advises limiting fruit juice, vegetable juice and smoothies to a combined total of 150ml per day. Crushing or juicing fruit releases sugars from the fruit structure, and frequent exposure can contribute to tooth decay. nhs.uk

A whole apple retains its fibre-containing structure and can be an easy way to add fruit to your day.

4. Apples Can Be Part of a Heart-Healthy Eating Pattern

You may have seen claims that apples specifically prevent heart disease or remove cholesterol from the arteries.

Those statements go further than the evidence supports.

It is more accurate to consider apples as part of a wider dietary pattern.

The NHS states that eating plenty of fruit and vegetables may help reduce the risk of health problems including heart disease and stroke. nhs.uk

Research continues into whether apples and their naturally occurring compounds have specific effects on cardiovascular and metabolic health.

A recent systematic review of human intervention studies reported some potentially favourable effects on certain markers, but the researchers also concluded that the available evidence was not sufficient to draw definitive conclusions. PubMed

So the sensible message is simple: eat apples because they are a nutritious fruit, not because they are a guaranteed treatment for heart disease.

5. Apples Can Be Included in a Balanced Diet

No individual fruit provides everything your body needs.

The NHS Eatwell Guide recommends obtaining your diet from several food groups, including fruit and vegetables, higher-fibre starchy foods, protein foods and dairy or suitable alternatives, while choosing appropriate amounts of fats and fluids. nhs.uk

Apples fit comfortably into this approach.

For example, you could have:

sliced apple with porridge,
an apple with lunch,
chopped apple with plain yoghurt,
apple in a fruit salad, or
an apple as a snack.

The overall quality of your diet matters more than eating one particular “superfood.”

6. What About Apples and Type 2 Diabetes?

Another common claim is that apples prevent type 2 diabetes.

This should be treated carefully.

Whole fruit can form part of a healthy diet, including for many people with diabetes, but no individual food should be presented as a guaranteed way to prevent or treat diabetes.

If you have diabetes and have been given individual dietary advice by your healthcare team, follow that advice.

Research into fruit intake and metabolic health is ongoing, and observational associations should not automatically be interpreted as proof that apples themselves prevent disease.

7. Do Apples Prevent Cancer?

It would be misleading to tell readers that apples prevent colon cancer or another particular cancer.

Fruit and vegetables are an important part of a healthy diet, and the NHS states that getting at least five portions of a variety of fruit and vegetables every day is associated with health benefits, including a lower risk of some cancers. nhs.uk

That is different from claiming that an individual apple prevents or treats cancer.

Cancer risk is influenced by many factors, and no single food should be promoted as a cancer cure or guaranteed preventive treatment.

8. Should You Eat Apple Skin?

For most people, the edible skin of an apple can be eaten.

Eating the whole fruit, including the skin, means you are not unnecessarily removing part of its fibre-containing structure.

Wash apples under clean running water before eating them.

If you personally prefer peeled apples, however, you can still include them as part of your fruit intake.

Healthy eating does not require forcing yourself to eat foods in a particular way that you strongly dislike.

9. Should You Eat Apple Seeds?

There is no nutritional reason to deliberately eat apple seeds.

Accidentally swallowing a few seeds while eating an apple is different from intentionally eating or crushing large quantities.

The simplest approach is to eat the flesh and skin if you enjoy them and discard the core and seeds.

There is no need to become anxious if you accidentally swallow an occasional seed.

Are Green Apples Healthier Than Red Apples?

There are many varieties of apples, including Granny Smith, Gala, Braeburn, Golden Delicious, Pink Lady and others.

Their sweetness, acidity, texture and nutritional composition can vary somewhat.

However, there is no need for most people to choose one colour of apple because they believe it has extraordinary health properties.

Choose varieties you enjoy and combine them with a wide variety of other fruits and vegetables.

Fresh, Cooked or Juiced: Which Is Better?

Fresh whole apples are a convenient option, but apples can also be cooked and incorporated into meals.

The nutritional profile of a dish depends on everything added to it.

For example, an apple used in a dessert containing large amounts of added sugar and saturated fat is different nutritionally from eating a whole apple.

Apple juice also differs from whole fruit.

Because juice contains free sugars and lacks the same intact fruit structure, the NHS recommends limiting the combined amount of fruit juice and smoothies to 150ml per day. nhs.uk

How Many Apples Should You Eat?

There is no requirement to eat a particular number of apples every day.

For adults, one medium apple counts as one portion towards the recommended minimum of five daily portions of fruit and vegetables. nhs.uk

Rather than trying to eat several apples simply because they are healthy, aim for variety.

For example, across a day you might choose an apple alongside different vegetables and other fruits.

The Bottom Line

Apples are nutritious, affordable and convenient for many people.

They provide fibre and other nutrients and can help you achieve your recommended fruit and vegetable intake.

But their benefits should not be exaggerated.

An apple does not guarantee protection from cancer, diabetes, high blood pressure, osteoporosis, heart disease or neurological disease.

The strongest approach is to include apples alongside a wide variety of fruits, vegetables and other nutritious foods as part of an overall balanced diet.

And while the old saying “an apple a day keeps the doctor away” is memorable, an apple is not a substitute for medical care when you need it.

12 Simple Ways to Live a Healthier Life Every Day

Living a healthier life does not necessarily require a complete lifestyle overhaul. Some of the most useful changes are small habits that can be repeated consistently.

Eating a balanced diet, being physically active, getting enough sleep, looking after your mental wellbeing and avoiding harmful habits all contribute to better overall health. The NHS includes healthy eating, exercise, sleep, healthy weight, reducing alcohol and stopping smoking among the important areas of healthy living. nhs.uk

Instead of trying to change everything at once, consider the following 12 practical ways to support your health and wellbeing.

1. Make Time to Relax

A busy schedule can make relaxation feel unimportant, but taking time away from work and responsibilities can be valuable for your wellbeing.

Relaxation does not have to mean spending hours doing nothing. It might involve reading, listening to music, gardening, taking a quiet walk, enjoying a hobby or simply sitting somewhere comfortable for a few minutes.

Try to identify activities that genuinely help you unwind and make room for them in your normal routine.

2. Accept What You Cannot Control

Not every difficult situation can be changed immediately.

Constantly focusing on things outside your control can add to feelings of stress and frustration. When faced with a difficult situation, ask yourself which parts you can realistically influence.

Put your energy into those things.

For circumstances you cannot change, concentrating on how you respond may be more productive than repeatedly worrying about the situation itself.

3. Use Slow Breathing When You Feel Stressed

When you feel tense, giving yourself a few quiet minutes may help you settle.

Sit somewhere comfortable and breathe slowly and naturally. Avoid forcing unusually deep breaths or holding your breath for long periods.

You can also combine breathing with other calming activities, such as taking a short walk or temporarily stepping away from whatever is causing you stress.

Persistent anxiety, panic or stress that interferes with everyday life deserves proper attention rather than simply being dismissed as something you have to tolerate.

4. Break Large Tasks Into Smaller Steps

Large responsibilities can feel overwhelming when viewed as one enormous task.

Breaking them into smaller, manageable steps can make it easier to decide where to begin.

For example, instead of writing “clean the house” on your list, divide it into individual rooms or smaller jobs.

The same approach can be used for work projects, studying, finances and even health goals.

Rather than deciding that you must suddenly “become healthy,” start with something specific, such as taking a daily walk or adding vegetables to one additional meal.

5. Eat a Varied, Balanced Diet

Healthy eating is not about one supposedly perfect food.

WHO describes a healthy diet as including a variety of foods and recommends limiting salt, free sugars, saturated fats and industrially produced trans fats. Foods such as vegetables, fruits, legumes, whole grains and other nutritious foods can all contribute to a balanced diet. World Health Organization

Your individual diet may vary according to your age, culture, preferences, health needs and available foods.

Try to focus on the overall quality of what you eat rather than relying on restrictive fad diets or claims that a single food can prevent or cure disease.

6. Move More During the Day

You do not have to spend your entire day in a gym to become more active.

Walking, cycling, household activities and planned exercise can all contribute to physical activity.

For adults aged 19 to 64, the NHS recommends at least 150 minutes of moderate-intensity activity a week or 75 minutes of vigorous-intensity activity, together with strengthening activities involving the major muscle groups on at least two days each week. Long periods of sitting should also be broken up with activity. nhs.uk

WHO recommends 150–300 minutes of moderate aerobic activity per week for adults, or the vigorous-activity equivalent. World Health Organization

If you are currently inactive, you do not have to reach these targets immediately. Start with an amount appropriate for you and gradually build up.

7. Plan Your Day Without Overloading It

A simple to-do list can help organise your priorities.

However, filling every available minute with tasks can defeat the purpose.

Choose the most important things that realistically need to be completed and allow some flexibility for unexpected events.

You may find it useful to divide tasks into categories such as:

Must do today
Important but can wait
Optional

This can make an intimidating list feel much more manageable.

8. Stay Connected With Other People

Good health involves more than diet and exercise.

Maintaining relationships with family members, friends and other trusted people can contribute to emotional wellbeing.

Make time for conversations, shared activities and laughter. If something is troubling you, speaking with somebody you trust can sometimes help you look at the situation differently.

At the same time, serious or persistent mental-health difficulties should not be treated as something that friendship alone must solve. Professional support may be appropriate.

9. Pay Attention to Persistent Symptoms

Do not ignore a physical or emotional problem simply because you hope it will disappear.

Many symptoms are minor and resolve by themselves, but persistent, worsening or concerning symptoms may require professional assessment.

If you are worried about a symptom or a change in your health, contact an appropriate healthcare professional for advice.

For urgent or potentially life-threatening symptoms, seek urgent medical assistance rather than relying on information found online.

10. Make Sleep a Priority

Sleep is an important part of overall health.

Try to maintain a regular sleep routine where practical and create an environment that makes it easier to wind down at night.

Persistent tiredness should not automatically be blamed on being busy. The NHS notes that tiredness can be related to lifestyle factors such as insufficient sleep, stress and diet, but ongoing fatigue can sometimes have an underlying medical cause. nhs.uk

If tiredness is severe, unexplained or does not improve with adequate rest and sleep, consider seeking medical advice.

11. Reduce Long Periods of Sitting

Exercise is important, but so is what happens during the rest of your day.

If your work or lifestyle involves sitting for long periods, try to get up and move regularly where possible.

Walk around, stretch your legs, take the stairs when appropriate or incorporate short periods of movement into everyday activities.

WHO advises adults to limit sedentary behaviour and notes that replacing sedentary time with physical activity, including light-intensity activity, provides health benefits. Iris

Small amounts of movement throughout the day can therefore complement your planned exercise.

12. Build Healthy Habits Gradually

One of the biggest mistakes people make is trying to transform their lifestyle overnight.

A strict new diet, an exhausting exercise programme and an unrealistic daily routine may be difficult to maintain.

Choose one or two achievable changes first.

You might begin by:

walking more frequently,
improving one meal each day,
establishing a more consistent bedtime,
taking regular breaks from prolonged sitting, or
making more time for activities that help you relax.

Once those behaviours become part of your routine, consider adding another healthy habit.

Consistency matters more than trying to achieve perfection.

A Healthier Life Starts With Small Steps

Living well is not about following a perfect routine every day.

It is about making choices that support your physical and mental wellbeing as consistently as circumstances allow.

Eat a varied and balanced diet, move regularly, prioritise sleep, maintain supportive relationships and seek professional healthcare when you need it.

Most importantly, make changes that are realistic enough to become part of your everyday life.
