Covid 19 is a communicable illness as a result of a new strain of coronaviruses. Coronaviruses entail related RNA viruses that lead to mild and letha respiratory tract infections. Coronavirus causes mild diseases such as the common cold and severe illnesses such as Severe Acute Respiratory Symptoms (SERS), COVID-19, and Middle East Respiratory Syndrome(MERS).
Coronaviruses were discovered in 1965 after causing the common cold.
In 2002, Southern China experienced SARS causing 8,000 infections and 774 deaths by July 2003.
Saudi Arabia experienced MERS in 2012, which killed 858 people and caused severe symptoms such as kidney failure.
Where did the coronavirus (Covid-19) originate from?
According to World Health Organization, Covid19 originated from the Huana market in Wuhan China in December 2019. The market sells different animals such as bats and pangolin, which are hosts for coronaviruses.
Bats might have caused the pandemic(SAR-CoV 2) since they are responsible for the 2002 SARS-CoV.
Thus, in January 2020, the government closed the market for disinfection after vendors and customers experienced unexplained pneumonia symptoms.
Is corona a biological weapon?
Covid-19 is believed to be a biological weapon due to differences in molecular biology.
The Covid-19, receptor binding motif seems to be strangely adapted to bind to human cells. Unlike SARS and SARS-CoV-1 which caused illness after staying for some time in human cells, Covid-19 appears to be pre-modified to attack humans.
SARS-CoV-2 is the only virus among Sarbecovirus to have spike protein, whose site appears furin cleavage that helps the host to break into human cells
Hence, after 2-4 weeks of infection, Covid-19 causes serious symptoms such as shortness of breath, fever, pneumonia, and even death.
What are the chances that Covid-19 might have escaped from the lab?
Covid-19 might have escaped from the lab at the Wuhan Institute of Virology since the institute focuses on coronaviruses.
The institute deals with RaTG13 which is 96.2% genetically similar to Covid-19. In 2002, the RaTG13 virus was discovered among miners that fell sick and some died after cleaning bat feces in a copper mine.
The lab took the bat specimen and develop chimeric viruses to minimize the growing cases of coronaviruses.
The creation of chimeric viruses entails the coding of the spike protein surface leading to the furin cleavage surface found in the Covid19 virus.
Nobel laureate at the California Institute of Technology, David Baltimore state” viruses don’t usually have that particular code for arginine, but human often do-a smoking gun”.
Baltimore believes that they are a possibility that the researchers at the institute tampered with the nucleotides by encoding the amino acid arginine. Such changes lead to molecular changes such as the furin cleavage protein site.
Based on its molecular structure, Covid-19 appears to be bioengineered and leaked through the lab.
