Reminiscent of the SARS virus was found in Chinese bats, can be dangerous for people. Whether waiting for us an epidemic?
Ebola virus and Zika together claimed thousands of lives and billions of dollars. There is currently no effective vaccine for any of these diseases.
The ability of this group of viruses to transfer from animals to humans is greater than originally thought. While most of the viruses must pass a series of improvements to make the epidemic viruses circulating among bats can quickly overcome the barrier of replication in human cells” said Vineet Menachery, one of epidemiologists at the University of North Carolina.
Scientists have isolated the Chinese family of bats (barbastella-barbastellus) similar to the SARS corona virus.
It was reproduced in the laboratory, in order to assess the potential to infect human and mouse cells. It turned out that the newly formed virus, known as WIV1-CoV, it connects to the same receptors, as SARS.
It was discovered that the virus WIV1 can easily and quickly replicate in the human respiratory tract tissues breeding, indicating the possibility of a direct transition to the people.
To be clear this virus can not jump on people, but if you have to come to his transfer to our body, WIV1 CoV has the potential to anchor a new outbreak of the disease with significant consequences both for public health and the global economy” said Menachery.
The researchers also found that the antibodies developed to treat SARS, have been effective in both samples, both human and animal. Unfortunately, not yet developed a process for the manufacture of antibodies on a large scale, enough to treat the disease.
What’s more, the SARS vaccine will not provide protection against the new virus due to slight differences in the viral sequences.
According to the CDC SARS mortality rate may be less than 1% for patients below 24 years old and more than 50% for those over 60 year old. Scientists believe that WIV1-CoV has similar potential to SARS.
