The World Health Organization (WHO) is conducting further investigations into a person who appears to have a virus in their body.
People will notice and indicate that the infection continues when there is a possibility of an outbreak in the future.
International researchers, including a team from the University of Guinea-Bissau, sequenced the genomes of nine samples taken from infected people during the current outbreak and compared previous outbreak sequences to help identify the cause.
The results suggest that the latest outbreak is “the result of a resurgence of tensions that previously erupted in West Africa,” the authors wrote in their analysis.
The Director of Emergency Preparedness and Response Cluster at the WHO Regional Office for Africa, Dr. “The similarities are big enough for us to declare that this is the same family of viruses,” said Salam Gue.
But the research was spearheaded by the deputy director of Concre University’s Center for Result at Formation an Infectology de Guinea (CERIG).
They decided to continue the sequence on additional samples to be more careful and provide a more secure answer to get a more complete sequence, he added.
In a separate report on the work, Kaita explained that public health and public safety conditions, which in previous Ebola survivors called for stigma, risks of physical and verbal violence for such an approach.
Guey said further investigations are now underway to see exactly what happened.
Guinea’s health ministry on February 14 announced a new outbreak of the Ebola virus in the country’s Nazareth region. As of March 25, 18 cases have been reported, including 14 confirmed and four probable cases. Nine people have died and 366 contacts are following.
According to researchers, the latest outbreak began just 200 km from the epicenter of the previous epidemic.
Sexually transmitted virus?
The nurse was the surviving wife’s mother-in-law, who is believed to have been infected with the virus for five years. After the spouse died of the Ebola virus, the nurse soon developed the disease and is believed to have transmitted it to others during the funeral. “This is how the outbreak could start,” Gue said.
Teams from CERFIGG then indexed nine samples of people tested positive for Ebola, identifying the maca variant in these samples.
Gue told CNN that the virus may be dormant and then sexually transmitted from one person to another or that the virus was present in the body and did not cause illness, but relapsed due to a mutation of the virus or a decline in host immunity, Gue told CNN.
“We continue to investigate epidemiology and anthropology to strengthen or exclude that hypothesis, but it is the strongest hypothesis we have so far,” Guye said.
Wim van Damme, a researcher and infectious disease specialist at the Institute of Tropical Medicine, Antwerp, warns that this transmission method will be a very rare occurrence. He said there were more than 10,000 Ebola survivors in West Africa, and this was the first case in five years.
He added that while many people think the infection was probably a case of sexual transmission. “It’s not for sure because the virus may be present in other parts of the body (primarily in the central nervous system).” But it also explains how the virus spreads from the nervous system to other humans.
“Supplementary investigations and epidemiological research are needed to determine what happened and to have a strong idea of what happened. There are a lot of facts that have given us enough information to respond,” Gue told CNN.
The WHO is working with West African affected governments and a task force has been formed. “The task force will move on to epidemiology, bioinformatics and the laboratory to see what we can learn from this experience and translate it into a program.”
Risk of future outbreaks
“The fact is that we need to follow these survivors for a longer period of time with frequent sperm analysis for the virus. We can also provide condoms for them,” said Dr. Meravi Aragave said.
“The community needs continued education. We are trying to reach out to the community through health workers so that they can be trusted,” Arega said, adding that the Africa CDC continues to provide psychological support to survivors and advise community partners and people.
The WHO says it will strengthen surveillance, disease screening and disease responses for Ebola-affected countries.
“The way we respond to Ebola and the way we are preventing Ebola will change. This is a disease that needs to be in the surveillance system and it needs the cooperation of the community, health workers, and it needs to happen.” A priority for health officials. , ”Gue said.
Ebola virus disease (EVD) is a rare but serious, often fatal disease in humans. The virus is usually spread by direct contact with blood, body fluids or tissues of infected people or animals.
The 2014-2016 Ebola epidemic in West Africa was the largest to date in Liberia, Sierra Leone and Guinea.
A total of 28,646 suspicious cases have been reported with 11,323 deaths.
