Corona virus spreading method is somehow un-usual, un-predictive & un-believable for which many people named it in different ways. In the language of Donald Trumph it is China virus when for others it is Wuhan virus & Chinese marked this as bat market virus. Whatsoever may it be, once the positive corona virus is there, the resultant cannot be forecasted. The whole World already lost around 7lakh precious human lives where as above 1crore people identified with positive virus. In India too above 17lakhs found positive where as 36, 587 died. In Odisha positive number is more than 33thousand & 187 died out of pandemic. In the first phase of epidemic, migrant Odiya labourers from 13 other state like Gujurat, Delhi, Tamil Nadu, West Bengal returned back to their Motherland. No sooner they reached, cov-19 positive number became doubled up. Research over cov-19 virus also started with the combined effort of RMRC & ILS. On Saturday in a joint press conference both the research institute informed that in Odisha around 225 migrant labourer with corona positive has been examined in order to know about type of virus particularly & there are 5type of virus found out of Genome survey named as 19A, 19B, 20A, 20B & 20C. the peculiarity with virus 20C is that, according to Darwin’s evolution theory it is more an Odisha product whereas 19A is having 90% similarities with Wuhan virus. More ever 19B 20A & 20B are similar to some Europian & few South East Asian countries which needs more research work & in August this will be started again. Now we have to wait & see, how many other variant of cov virus would be discovered further.
