What is a virus that does not belong to our traditional cognition?

The virus that does not belong to our traditional cognition is COVID-19.

1, a new study found that COVID-19 increased 1000 times in some patients, which is different from many traditional cognition, because in traditional virus cognition, it has a characteristic for infectious diseases. With the inheritance of the second, third and fourth generations, the toxicity of the virus may decrease.

2. However, COVID-19 is different from previous bacterial infectious diseases. COVID-19 belongs to RNA structure, and sudden mutation has more unpredictable results than bacteria with DNA structure, which is why French researchers found that the toxicity of virus in some patients is 1000 times that of ordinary virus. According to Italy, which has the worst epidemic and the highest mortality, the COVID-19 gene sequence in Italy is completely different from the COVID-19 gene sequence in China, which indicates that either COVID-19 and China in Italy have different origins, or COVID-19 has mutated after entering Italy.
