The 2019 Novel Coronavirus was referred to by researchers as Severe Acute Respiratory Syndrome Coronavirus 2 or SARS-CoV-2. It is the virus behind the Coronavirus Disease 2019 or COVID-19. In November, researchers first discovered the virus, which came from Wuhan, Hubei of China. The Chinese government implemented measures to restrain the propagation of the virus, however, it wasn’t possible to control, and it propagated around the world.
The World Health Organization (WHO) announced that the COVID-19 outbreak became a public health emergency of worldwide concern on January 30, 2020. The outbreak turned pandemic on March 11, 2020. President Trump announced on March 13, 2020 a national emergency because of the COVID-19 crisis. HHS Secretary Alex Azar proclaimed the U.S.A. under public health emergency starting March 15, 2020 at 6:00 pm because of the SARS-CoV-2 pandemic.
SARS-CoV-2 is remarkably contagious, and COVID-19 has a high fatality rate. The fatality rate is hard to establish because a lot of people who tested positive for SARS-CoV-2 just have fairly mild signs or symptoms and never get medical assistance. Testing has been inconsistent at the beginning in a lot of places and test kits have a limited supply. According to the limited data obtained, the fatality rate varies from under 1% to 7%. At the beginning of March, WHO approximated a fatality rate of 3.4%; but, the information on which these numbers are taken might be incorrect because of the progressing circumstance.
One of the crucial issues that was responsible for the quick spread of SARS-CoV-2 is the lengthy incubation period prior to experiencing signs and symptoms, during which period of time infected persons could pass on the virus. It could last up to 14 days before infected persons show symptoms. 10 days is the average incubation time.
This is a quickly evolving situation that will probably get significantly worse until the curbing of the spread of the disease. Without a vaccine to fight the virus, the entire population needs to take steps to restrict exposure and avoid the spread of the COVID-19 disease.
There is substantial development towards creating a vaccine in a short period of time. A number of pharma companies have already made potential vaccines, yet they are still to be tested for the protection of people in clinical studies. Even though the procedure may be fast-tracked, it is not likely to have a vaccine before 2021.
