Ebola Virus Has Become More Contagious
With the scourge of the Ebola virus not seeming to abate, the scientists who are working on ways to combat the virus are giving out warnings that the deadly virus may have mutated. The worst news is that the virus has in all likelihood become even more contagious. Till date 22,000 people have been infected with Ebola and 8,795 have died in Guinea, Sierra Leone and Liberia. Hundreds of blood samples are being tested to come to a conclusion. Mutations in virus are a normal thing and Ebola is an RNA virus – like HIV and influenza – which have a high rate of mutation. As human geneticist Dr Anavaj Sakuntabhai said, “We’ve now seen several cases that don’t have any symptoms at all, asymptomatic cases,” “These people may be the people who can spread the virus better, but we still don’t know that yet. A virus can change itself to less deadly, but more contagious and that’s something we are afraid of.”
More Infection Can Be Because Of Denser Settlement
While some scientists are saying that the numbers of infections have increased, it may be because the number of people in the area is higher than in previous cases. Even more alarming is the fact that the virus is getting more time and host to incubate and mutate in. Ultimately, the virus may become air borne.
No Immediate Proof Of Virus Becoming Air Borne
Till date, there has been no case or instance where the virus has passed through air. Therefore, there is no need to panic for the time being. For now, the researchers are making use of a method called genetic sequencing to track changes in the genetic make-up of the virus.
