Ebola outbreak in Guinea From the past of the epidemic

V.Iral genetic sequences from current Ebola cases in Guinea and from the West African outbreak 2014–2016 are almost identical, according to recent analyzes, which indicates that the new outbreak was triggered by someone who harbored the virus for five years or more. The New York Times Reports.

Ebola cases were identified in Guinea in late January and the country declared an outbreak on February 13. A total of 18 people tested positive for the virus and nine people died.

The Ebola virus can linger in the body long after a person has recovered and sometimes trigger or spread the disease when reactivated. However, around 500 days was the longest recorded interval. Given the length of time since the last Ebola crisis in West Africa, in which more than 11,000 people were killed, researchers had assumed that animals said the new outbreak came from animals STAT.

Three independent research groups sequenced and compared the genomes of the Ebola virus from the current outbreaks and the 2013–2016 outbreaks. Findings published on virological.org, a discussion forum for the molecular evolution and epidemiology of viruses, stated in an analysis that the fact that the samples shared several mutations “makes the new cases unlikely to be the result of one new overflow from the animal reservoir, but are directly related to human cases in the EVD 2013–2016 in West Africa [Ebola virus disease] Outbreak. “The other two analyzes come to similar conclusions.

“I was completely shocked,” said Angela Rasmussen, a virologist at the Georgetown Center for Global Health Science and Security STATin response to the results.

“A new outbreak of latent infection 5 years after the end of an epidemic is scary and new,” says Eric Delaporte, an infectious disease doctor at the University of Montpellier who is part of one of the three teams that carried out the genetic analysis, tells science.

A separate Ebola outbreak was recently reported in the Democratic Republic of the Congo.
