Scientists at the University of Hong Kong claim to have the first one to be reinfected with the virus that causes covid-19.
Genetic testing revealed that a 33-year-old man returning to Hong Kong from Spain in mid-August had another strain of coronavirus that had already become inflamed about in March, said microbiologist Kelvin Kai-Wang To. who led the job.
The guy had mild symptoms the first time and none at the time; its maximum recent infection detected by screening and testing at Hong Kong Airport.
“This shows that some other people are not immune for life,” opposed to the virus if they have already had it, To said. “We don’t know how many more people can become infected again. There are other people out there.
The article has been accepted through the journal Clinical Infectious Diseases, but has still been published and some independent experts have asked for caution until full effects are available.
The question of whether others who have had covid-19 are immune to new infections and for how long they are key problems that have implications for vaccine progression and social decisions and back to school.
Although a user would possibly become inflamed for a moment, it is not known whether he opposes a serious illness, as the immune formula regularly remembers how to manufacture antibodies opposed to a virus he has already seen.
It is not known what other virus will have to be to cause a disease, however, new studies suggest that “covid patients will not be content with preventive measures” and continue to distance themselves from the social, dressed in masks and other tactics to decrease infection. , To the said.
Two paperless experts in the paintings agree.
“We know that reinfection is an option and I think it’s very revealing” that happened in this case, said Dr. Jesse Goodman, former leading scientist of the U.S. Food and Drug Administration now at Georgetown University. “If there is a reinfection, it suggests the option that there was residual immunity … that helped protect the patient” from a new illness, Goodman said.
However, “if immunity decreases due to an herbal infection, this can also be a challenge for vaccines” and would possibly mean that booster injections are needed, he added.
Julie Fischer, a microbiologist at CRDF Global, a nonprofit fitness organization in Arlington, Virginia, said the review provided compelling evidence that reinfection can occur.
“The genuine is what it means for the severity of the disease” if it happens, and if those other people can infect other people, he said.
An expert saw the report as good news. Dr. Paul Offit, a vaccine expert at The Children’s Hospital of Philadelphia, said it is encouraging that the reported reinfection has not had symptoms.
“This is a victory for me” because it suggests that a first infection may a user of a moderate to severe illness at the time, he said in an interview published through the Journal of the American Medical Association.
A mid-May survey of Sermo, which shares information with doctors, found that 13% of the 4,173 doctors who responded to the idea that they had treated one or more reinfected patients. Among respondents, 7% of those in the United States and 16% of those in other countries believe they have noticed such a case.
However, fitness officials also questioned whether other people who tested positive long after their initial illness simply showed symptoms of not getting rid of the virus at all than re-inflamed.
