What are the new features of the new COVID-19 mutant virus?

The emergence of new mutant viruses has led to an increase in virus transmission, and the epidemic situation in some places has continued to deteriorate. COVID-19 also presents new features. For example, infected patients may face long-term sequelae. Many young Japanese COVID-19 patients show symptoms such as burnout, dyspnea, alopecia, memory loss and depression after rehabilitation. New features also include: repeated infection, recurrence, and long-term or intermittent incubation period.

In the latest weekly report of China CDC, Gao Fu, director of China CDC, said that COVID-19 will become a long-term epidemic disease in the world or local areas, and this will be one of the uncertain factors of 20021.

Extended data

Multi-country mutation COVID-19 cases increased.

At present, mutant COVID-19 has been found in most countries in the world, and the spread speed of mutant virus is gradually accelerating.

On 19, the head of the German Center for Disease Control and Prevention warned that the COVID-19 mutant strain found in Britain is currently spreading on a large scale in Germany, and its proportion in the total number of newly confirmed cases is rising sharply, reaching nearly a quarter, and will continue to increase, which will increase the difficulty of fighting the epidemic in this country.

According to Italian statistics, Romagne, Tuscany, Priya and Emilia all accounted for more than one third of the newly diagnosed cases, and Ma Erkai, umbria and molise even accounted for more than half.

French health minister and experts introduced on June 5438+08 that at present, at the national level, 36% of new cases in France were found in Britain, and 5% were found in South Africa and Brazil.

The data model of COVID-19 epidemic released by Canadian Public Health Bureau on June 5438+09 shows that the threat of mutant COVID-19 is becoming more and more obvious. If stricter epidemic prevention measures are not taken, the third wave of epidemic will come soon.

In addition, different new variants of COVID-19 have been found in Finland and Japan, which is different from those previously found in Britain and other countries.
