Coronavirus was first detected in China; in the town of Corona in 2019 to be precise. It is believed that the coronavirus originated from the Hunan seafood market at Wuhan, China where bats, snakes, raccoon dogs, palm civets, and other animals are sold, and vastly spread to about 109 countries. The zoonotic source of SARS-CoV-2 is not confirmed. Moreover, the sequence-based analysis suggested bats as a critical reservoir. DNA recombination was found to be involved at spike glycoprotein which assorted SARS-CoV, thus could be the reason for cross-species transmission and rapid infection.
Until now, no promising clinical treatments or prevention strategies have been developed against human coronavirus. However, the researchers are working helter-skelter to develop efficient therapeutic approaches to cope with the novel coronavirus.
Many biologists will ask that 'how possible is it for infections to be transmitted from seafood to human'? Well, it has been concluded that the homologous recombination event at the S protein of RBD region enhanced the transmission ability of the virus.
Reasons Why it Spread World Wide.
During Chinese battle to recover from the virus, many nations called it a rumour hooks, they thought that the disease was a result of the consumption of detestable and abominable animals or creatures, so they failed to look for preventive measures or cure for the pandemic, and this took a dangerous turn.
Besides, many nations poured insult on the Chinese. They forgot to make a preventive strategy. This singular act led to the death of millions of people in the world. Many infected people moved to different nations. They infected people-both small and great, rich and poor.
Furthermore, pandemonium erupted in the countries whose people contracted the nasty deadly disease. They ran helter-skelter looking for information and remedy. At that time, the Chinese were getting over the problem. The information about the pandemic came rather too late.
Many microbiologists were asked to conducted experiment on the infected. Hence these were their observation:
-It is the world most deadly pandemic
-the virus cannot stay in the atmosphere a long time
-It can be contracted when one touches the face with the hands
-It can remain on a surface for many hours
-People within the ages of 0-15 and 65 above are vulnerable including
- People suffering from terminal diseases like Asthma, Tuberculosis and the likes.
It's therefore advisable to practice social distancing and regular washing of hands.
