Ebola virus can be transmitted in postmortem care settings through unsafe handling of remains. Only personnel trained in handling infected human remains and wearing recommended PPE should touch or move any human remains from a person who has died from Ebola. Do not wash or clean the body.
Typically, if infectious virus is detected for days to weeks, the genome of the virus can be detected for months to years. One study looking at how long Ebola virus might survive after death could detect the infectious virus 10 days postmortem but still detected the virus genome 10 weeks later.
Ebola is a deadly disease caused by a virus. There are five strains, and four of them can make people sick. After entering the body, it kills cells, making some of them explode. It wrecks the immune system, causes heavy bleeding inside the body, and damages almost every organ.
In most cases, people who have completely recovered from Ebola disease do not become reinfected. However, many survivors suffer from health issues after recovery from Ebola. The most commonly reported complications are: Tiredness.
The incubation period for Ebola – meaning the time after infection and before symptoms appear – is 2 to 21 days. People with Ebola are not contagious until they begin having symptoms. People who have died from Ebola remain contagious.
The average EVD case fatality rate is around 50%. Case fatality rates have varied from 25% to 90% in past outbreaks. Community engagement is key to successfully controlling outbreaks.
Unlike a cold or the flu, the Ebola virus is not spread by tiny droplets that remain in the air after an infected person coughs or sneezes. Ebola is spread between humans when an uninfected person has direct contact with body fluids of a person who is sick with the disease or has died.
Primary signs and symptoms of Ebola disease often include some or several of the following: Fever. Aches and pains, such as severe headache and muscle and joint pain.
Ebola is a virus that causes severe inflammation and tissue damage throughout the body. It is known as a hemorrhagic fever virus, because it can cause problems with the clotting system of the body and lead to internal bleeding, as blood leaks from small blood vessels.
It kills between 25% and 90% of those infected – about 50% on average. Death is often due to shock from fluid loss, and typically occurs between six and 16 days after the first symptoms appear. Early treatment of symptoms increases the survival rate considerably compared to late start.
The case-fatality rate is between 20% and 90% depending on the virus species [10, 11]. Zaire Ebola virus species has the highest mortality rate (60%-90%) followed by the Sudan Ebola virus species (40%-60%).
In addition, EBOV causes liver, lungs and kidneys to shut down their functions and the blood vessels to leak fluid into surrounding tissues.
Infection risks from dead bodies
Tuberculosis, Hepatitis B and C, HIV/AIDS, Creutzfeldt-Jakob disease, meningococcal disease, and Group A streptococcal disease are considered to pose the greatest risks for those handling or in contact with recently dead bodies.
Ebolaviruses can survive on dry surfaces, like doorknobs and countertops for several hours; in body fluids like blood, ebolaviruses can survive up to several days at room temperature. Cleaning and disinfection should be performed using a hospital-grade disinfectant.
Ebola case fatality rates have varied from 25% to 90% in past outbreaks. However, with the currently available effective treatment, patients have a significantly higher chance of survival if they are treated early and given supportive care.
That's because viruses are small molecules that produce only a handful of proteins, so there are fewer "targets" for treatment, Gatherer said. For this same reason, it has been hard to develop a vaccine against Ebola; a person's immune system (which is primed by vaccines) has a small target, Gatherer said.

Does Ebola really make people bleed from their eyes? Yes. Some, but not all, patients may experience bleeding from orifices — one of the more unusual and memorable symptoms of viral hemorrhagic fevers like Ebola. In later stages of the disease, some people bleed from the eyes, nose, ears, mouth, and rectum.
Signs and symptoms of Ebola include fever, severe headache, muscle pain, weakness, fatigue, vomiting, diarrhea, stomach pain, and unexplained bleeding. The incubation period for Ebola, from exposure to when signs or symptoms appear, can be anywhere from 2 to 21 days. The average is 8 to 10 days.
The Ebola virus can turn a person's blue eyes green, according to a study about an American physician who contracted the virus in Sierra Leone and then watched his eye color change.
The Ebola outbreak in West Africa is the world's deadliest to date and the World Health Organization has declared an international health emergency as more than 3,850 people have died of the virus in Guinea, Liberia, Sierra Leone and Nigeria this year.
ERVEBO® (Ebola Zaire Vaccine, Live also known as V920, rVSVΔG-ZEBOV-GP or rVSV-ZEBOV) is approved by the U.S. Food and Drug Administration (FDA) for the prevention of disease caused by Ebola virus (EBOV; species Zaire ebolavirus) in individuals 18 years of age and older as a single dose administration.
Natural reservoir
The natural reservoir for Ebola virus is believed to be fruit bats from the Pteropodidae family.
Since EVD was first characterized in 1976, there have been 38 country-specific outbreaks, including the outbreak in the DRC. The total estimated EVD deaths from 1976 to 2020 is 15,266. The median number of deaths for all 38 outbreaks is 29 with a range of 0 to 4,809 (Table 1).
Ebola virus disease is a severe, often fatal, zoonotic filovirus infection (fig 1 ). There are five species: Zaire ebolavirus, Sudan ebolavirus, Taï Forest ebolavirus, Bundibugyo ebolavirus, and Reston ebolavirus.
