Will there be a large-scale “secondary infection”?

Récemment, Maria Van Kokhoff, technical director of WHO’s health emergency project, said that there are currently more than 80,000 new coronavirus gene sequences in the world, and most of the mutations will not affect the infectivity and severity of the virus. The WHO has established a special working group to confirm different mutations and study their possible impact on virus behavior.

toutefois, the genetic sequence of the two infections of the patient discovered this time is obviously different. Does the emergence of this case mean that the future virus mutation will bring a large-scale “second infection” risk?

“Small virus mutations will not have a big impact on the epidemic situation, and dozens of amino acid mutations will not have much impact on the structure of the entire virus.” Wu Zunyou said.

He emphasized that this case in Hong Kong is a case, but there is also an important reminder: After recovering from the new coronary pneumonia patients, they can still be infected with the new coronavirus, and there may be patients with similar conditions.

Shenzhen Medico manufacturer warmly reminds that the best way to prevent a pandemic is to isolate and prevent human-to-human transmission, and with the launch of vaccines and mass vaccination, this risk will become smaller and smaller.
