1. What is Ebola virus disease?
Ebola virus disease (formerly known as Ebola haemorrhagic fever) is a severe, often fatal illness, with a death rate of up to 90% (almost 90% of the people will Ebola may die). The illness affects humans and nonhuman primates (monkeys, gorillas and chimpanzees).
Ebola first appeared in 1976 in two simultaneous outbreaks, one in a village near the Ebola River in the Democratic Republic of Congo, and the other in a remote area of Sudan.
The origin of the virus is unknown but fruit bats (Pteropodidae) are considered the likely host of the Ebola virus, based on available evidence.
2. How do people become infected with the virus?
In the current outbreak in West Africa, the majority of cases in humans have occurred as a result of human‐to‐human transmission.
Infection occurs from direct contact through broken skin or mucous membranes with the blood, or other bodily fluids or secretions (stool, urine, saliva, semen) of infected people. Infection can also occur if broken skin or mucous membranes of a healthy person come into contact with environments that have become contaminated with an Ebola patient’s infectious fluids such as soiled clothing, bed linen, or used needles.
More than 100 health‐care workers have been exposed to the virus while caring for Ebola patients.
This happens because they may not have been wearing personal protection equipment or were not properly applying infection prevention and control measures when caring for the patients. Healthcare providers at all levels of the health system – hospitals, clinics, and health posts – should be briefed on the nature of the disease and how it is transmitted, and strictly follow recommended infection control precautions.
WHO does not advise families or communities to care for individuals who may present with symptoms of Ebola virus disease in their homes. Rather, seek treatment in a hospital or treatment centre staffed by doctors and nurses qualified and equipped to treat Ebola virus victims. If you do choose to care for your loved one at home, WHO strongly advises you to notify your local public health authority and receive appropriate training, equipment (gloves and personal protective equipment [PPE]) for treatment, instructions on proper removal and disposal of PPE, and information on how to prevent further infection and transmission of the disease to yourself, other family members, or the community.
Additional transmission has occurred in communities during funerals and burial rituals. Burial ceremonies in which mourners have direct contact with the body of the deceased person have played a role in the transmission of Ebola. Persons who have died of Ebola must be handled using strong protective clothing and gloves and must be buried immediately. WHO advises that the deceased be handled and buried by trained case management professionals, who are equipped to properly bury the dead.
People are infectious as long as their blood and secretions contain the virus. For this reason, infected patients receive close monitoring from medical professionals and receive laboratory tests to ensure the virus is no longer circulating in their systems before they return home. When the medical professionals determine it is okay for the patient to return home, they are no longer infectious and cannot infect anyone else in their communities. Men who have recovered from the illness can still spread the virus to their partner through their semen for up to 7 weeks after recovery. For this reason, it is important for men to avoid sexual intercourse for at least 7 weeks after recovery or to wear condoms if having sexual intercourse during 7 weeks after recovery.
Generally, a person must come into contact with an animal that has Ebola and it can then spread within the community from human to human.
3. Who is most at risk?
During an outbreak, those at higher risk of infection are:
• Health workers;
• Family members or others in close contact with infected people; and
• Mourners who have direct contact with the bodies of the deceased as part of burial ceremonies.
More research is needed to understand if some groups, such as immuno‐compromised people or those with other underlying health conditions, are more susceptible than others to contracting the virus.
Exposure to the virus can be controlled through the use of protective measures in clinics and hospitals, at community gatherings, or at home.
4. What are typical signs and symptoms of infection?
Typical signs and symptoms include:-
• onset of fever,
• intense weakness,
• muscle pain,
• and sore throat
This is followed by
• impaired kidney
• and liver function, and
• in some cases, both internal and external bleeding.
Please note that laboratory findings include low white blood cell and platelet counts, and elevated liver enzymes.
The incubation period, or the time interval from infection to onset of symptoms, is from 2 to 21 days.
Please note that!
5. When should someone seek medical care?
If a person has been in an area known to have Ebola virus disease or in contact with a person known or suspected to have Ebola and they begin to have symptoms, they should seek medical care immediately.
Any cases of persons who are suspected to have the disease should be reported to the nearest health centre without delay. Prompt medical care is essential to improving the rate of survival from the disease. It is also important to control spread of the disease and infection control procedures need to be started immediately.
6. What is the treatment?
Severely ill patients require intensive supportive care. They are frequently dehydrated and need intravenous fluids or oral rehydration with solutions that contain electrolytes. There is currently no specific treatment to cure the disease. Some patients will recover with the appropriate medical care.
To help control further spread of the virus, people that are suspected or confirmed to have the disease should be isolated from other patients and treated by health workers using strict infection control precautions.
7. What can I do? Can it be prevented? Is there a vaccine?
Currently, there is no licensed medicine or vaccine for Ebola virus disease, but several products are under development.
8. Ways to prevent infection and transmission
While initial cases of Ebola virus disease are contracted by handling infected animals or carcasses, secondary cases occur by direct contact with the bodily fluids of an ill person, either through unsafe case management or unsafe burial practices.
During the current outbreak in West Africa, most of the disease has spread through human‐to‐human transmission. Several steps can be taken to help in preventing infection and limiting or stopping transmission.
You need to know the following:
• Understand the nature of the disease, how it is transmitted, and how to prevent it from spreading further. (For additional information, please see the previous questions about Ebola virus disease in this FAQ.)
• Listen to and follow directives issued by the Ministry of Health.
• If you choose to care for an ill person in your home, notify public health officials of your intentions so they can train you and provide appropriate personal protective equipment (PPE) (gloves, impermeable gown, boots/closed shoes with overshoes, mask and eye protection for splashes), as well as instructions as a reminder on how to properly care for the patient, protect yourself and your family, and properly dispose of the PPE after use.
Please Note that!
• When visiting patients in the hospital or caring for someone at home, hand washing with soap and water is recommended after touching a patient, being in contact with their bodily fluids, or touching his/her surroundings.
• People who have died from Ebola should only be handled using appropriate protective equipment and should be buried immediately by public health professionals who are trained in safe burial procedures.
• Individuals should reduce contact with high‐risk infected animals (i.e. fruit bats, monkeys, or apes. If you suspect an animal is infected, do not handle it. Animal products (blood and meat) should be thoroughly cooked before eating.
9. What about health workers? How should they protect themselves while caring for patients?
It is important to know that health workers treating patients with suspected or confirmed illness are at higher risk of infection than other groups. During an outbreak a number of important actions will reduce or stop the spread of the virus and protect health workers and others in the health‐care setting. These actions are called “standard and other additional precautions” and are evidence‐based recommendations known to prevent the spread of infections. The following questions and answers describe the precautions in detail.
Should patients with suspected or confirmed Ebola virus be separated from other patients?
Isolating patients with suspected or confirmed Ebola virus disease in single isolation rooms is recommended. Where isolation rooms are not available, it is important to assign designated areas, separate from other patients, for suspected and confirmed cases. In these designated areas, suspect and confirmed cases should also be separate. Access to these areas should be RESTRICTED, needed equipment should be dedicated strictly to suspected and confirmed EVD treatment areas, and clinical and non‐clinical personnel should be exclusively assigned to isolation rooms and dedicated areas.
Are visitors allowed in areas where patients suspected or confirmed Ebola virus disease are admitted?
Stopping visitor access to patients infected with EVD is recommended. If this is not possible, access should be given only to those individuals, who are necessary for the patient’s well‐being and care, such as a child’s parent.
Is protective equipment required when caring for these patients?
• In addition to standard health‐care precautions, health‐care workers should strictly apply recommended infection control measures to avoid exposure to infected blood, fluids, or contaminated environments or objects – such as a patient’s soiled linen or used needles.
• All visitors and health‐care workers should rigorously use what is known as personal protective equipment (PPE). PPE should include at least: gloves, an impermeable gown, boots/closed shoes with overshoes, a mask, and eye protection for splashes (goggles or face shields).
Is hand hygiene important?
Hand hygiene is essential and should be performed:
• before putting on gloves and wearing PPE on entry to the isolation room/area;
• before any clean or aseptic procedures is being performed on a patient;
• after any exposure risk or actual exposure with a patient’s blood or body fluids;
• after touching (even potentially) contaminated surfaces, items, or equipment in the patient’s
• surroundings; and
• after removal of PPE, upon leaving the isolation area.
It is important to note that neglecting to perform hand hygiene after removing PPE will reduce or negate any benefits of the PPE.
Either an alcohol‐based hand rub or soap and running water can be used for hand hygiene, applying the correct technique recommended by WHO. It is important to always perform hand hygiene with soap and running water when hands are visibly soiled. Alcohol‐based hand rubs should be made available at every point of care (at the entrance and within the isolation rooms and areas); running water, soap, and single use towels should also be always available.
What other precautions are necessary in the health‐care setting?
Other key precautions are safe injection and phlebotomy procedures, including safe management of sharps, regular and rigorous environmental cleaning, decontamination of surfaces and equipment, and management of soiled linen and of waste.
In addition, it is important to ensure safe processing of laboratory samples from suspected or confirmed patients with EDV and safe handling of dead bodies or human remains for post‐mortem examination and burial preparation. Any health‐care workers and other professionals undertaking these tasks in connection with suspected or confirmed patients with Ebola virus disease should wear appropriate PPE and follow precautions and procedures recommended by the Ministry of Health and WHO.
10. What about rumours that some foods can prevent or treat the infection?
The Ministry of Health strongly recommends that people seek credible health advice about Ebola virus disease from their nearest health facility.
While there is no specific drug against Ebola, the best treatment is intensive supportive treatment provided in the hospital by health workers using strict infection control procedures. The infection can be controlled through recommended protective measures.
11. How does the Ministry of Health protect the citizens during outbreaks?
The Ministry of Health provides technical advice to health facilities and communities to prepare for and respond to Ebola outbreaks.
Ministry of Health actions include:
• disease surveillance and information‐sharing across the country to remain alert as the outbreak is being reported in other countries;
• Investigate and contain health threats when they occur – such as on‐site
• help to identify sick people and track disease patterns;
• advice on prevention and treatment options;
• deployments of experts and the distribution of health supplies (such as personal protection gear
• Mobilize health workers within and outside Malawi to assist in managing the outbreak
• communications to raise awareness of the nature of the disease and protective health measures
• Control transmission of the virus; and
12. Is it safe to travel during an outbreak? What is the Ministry of Health and WHO’s travel advice?
During an outbreak, WHO reviews the public health situation regularly and recommends any travel or trade restrictions, if necessary, and may inform national authorities to implement it. at present, WHO is currently reviewing its recommendations for travel and expects to issue advice in the coming days.
While travellers should always be vigilant with regard to their health and those around them, the risk of infection for travellers is very low since person‐to‐person transmission results from direct contact with the body fluids or secretions of an infected patient.
Is it safe to travel with persons who have Ebola?
As with any illness or disease, it is always possible that a person who has been exposed to Ebola virus may choose to travel. If the individual has not developed symptoms (see FAQ #4), they cannot transmit EVD to those around them. If the individual does have symptoms, they should seek immediate medical attention at the first sign they are feeling unwell. This may require either notifying the flight crew or ship crew or, upon arrival at a destination, seeking immediate medical attention. Travellers who show initial symptoms of EVD should be isolated to prevent further transmission. Although the risk to fellow travellers in such a situation is very low, contact tracing is recommended under these circumstances.
Is it safe to travel to West Africa on business or to visit family and friends?
According to the World Health Organization, the risk of a tourist or businessman/woman becoming infected with Ebola virus during a visit to the affected areas and developing disease after returning is extremely low, even if the visit included travel to the local areas from which primary cases have been reported.
For a person to get Ebola, it requires direct contact with blood, secretions, organs or other body fluids of infected living or dead persons or animal, all of which are unlikely exposures for the average traveller. In any event, tourists are advised to avoid all such contacts.
If you are visiting family or friends in the affected areas, the risk is similarly low, unless you have direct physical contact with a person who is ill or who has died. If this is the case, it is important to notify public health authorities and engage in contact tracing. Contact tracing is used to confirm you have not been exposed to EVD and to prevent further spread of the disease through monitoring.
Is Malawi under threat of Ebola?
Just like other countries, the threat of Ebola is real for Malawi and all necessary precautions are currently being undertaken to prevent its occurrence. At the moment when WHO has not issued any international travel ban, all what is being done is to strengthen the local systems through public education and preparedness. It is important that the general public get the right information through all the appropriate media to avoid panic and fear.
Here is the WHO’s general travel advice
• Travellers should avoid all contact with infected patients.
• Health workers traveling to affected areas should strictly follow WHO‐recommended infection control guidance.
• Anyone who has stayed in areas where cases were recently reported should be aware of the symptoms of infection and seek medical attention at the first sign of illness.
• Clinicians caring for travellers returning from affected areas with compatible symptoms are advised to consider the possibility of Ebola virus disease.
