A 33-year-old man inflamed with coronavirus at a time more than 4 months after his first fight, the first documented case of the so-called reinfection, researchers in Hong Kong reported Monday.
The discovery was not unexpected, especially given the millions of people who have become inflamed around the world, experts said. And the guy had no symptoms at the time, suggesting that past exposure didn’t save you reinfection, his immune formula somehow controlled the virus.
“At the time the infection was absolutely asymptomatic, her immune reaction prevented the disease from getting worse,” said Akiko Iwasaki, an immunologist at Yale University who was not concerned about the paintings, but reviewed the report at the request of the New York Times. kind of an old example of how immunity paints. “
However, others who have no symptoms can transmit the virus to others, emphasizing the importance of vaccines, Dr. Iwasaki said. In the case of man, he added, “an herbal infection created an immunity that prevented the disease but not reinfection. “
“To provide collective immunity, a powerful vaccine is to induce immunity that prevents reinfection and disease,” Dr. Iwasaki said.
Doctors have reported several cases of suspected reinfection in the United States and elsewhere, but none of these cases have been demonstrated by rigorous monitoring. Recovered Americans are known to bring viral fragments for weeks, which can cause positive effects on control in the absence of viruses. .
But researchers in Hong Kong sequenced the virus from human infections and discovered differences, suggesting that the patient had become inflamed for a moment.
