Corona Virus

Corona virus is a rapid growing virus and research said it originated from snakes, now it is easy for researchers to find cure of the fatal disease.

World Health organization defines that Coronaviruses are zoonotic, meaning they are transmitted between animals and people.

Detailed investigations found that SARS-CoV was transmitted from civet cats to humans and MERS-CoV from dromedary camels to humans. Several known corona viruses are circulating in animals that have not yet infected humans.

Now a days, world is facing the danger of Novel Coronavirus or 2019-nCoV, started spreading in December 2019 from Chinese port city Wuhan. The city is now quarantined by Chinese government to reduce global outrage of the virus. 106 death has been confirmed due to the deadly virus.

Wuhan – the city of 11 million, where a new strain of coronavirus is believed to have originated, is one of almost 20 Chinese cities to have been quarantined in an attempt to curb the spread of the virus during the Lunar New Year or Spring Festival, traditionally China’s busiest travel season.

According to Science daily, “the new study on 2019-nCoV notes that patients who became infected with the virus — which is a type of virus called a coronavirus and was named 2019-nCoV by the World Health Organization — were exposed to wildlife animals at a wholesale market, where seafood, poultry, snakes, bats, and farm animals were sold.”

“By conducting a detailed genetic analysis of the virus and comparing it with available genetic information on different viruses from various geographic locations and host species, the investigators concluded that the 2019-nCoV appears to be a virus that formed from a combination of a corona virus found in bats and another corona virus of unknown origin.”

“The resulting virus developed a mix or “recombination” of a viral protein that recognizes and binds to receptors on host cells. Such recognition is key to allowing viruses to enter host cells, which can lead to infection and disease.”

“Finally, the team uncovered evidence that the 2019-nCoV likely resided in snakes before being transmitted to humans. Recombination within the viral receptor-binding protein may have allowed for cross-species transmission from snake to humans.”

“Results derived from our evolutionary analysis suggest for the first time that snake is the most probable wildlife animal reservoir for the 2019-nCoV,” the authors wrote. “New information obtained from our evolutionary analysis is highly significant for effective control of the outbreak caused by the 2019-nCoV-induced pneumonia.”

An accompanying editorial notes that although the ultimate control of emerging viral infections requires the discovery and development of effective vaccines and/or antiviral drugs, currently licensed antiviral drugs should be tested against the 2019-nCoV.
