New research: Coronavirus re-infectation is more common to older people

A study published by prestigious medical magazine “Lancet” found that only 0.65 percent of people came up positive for COVID-19 for the second time after being infected during the first and second waves of pandemic in Denmark.

This is much lower than 3.27 percent, which proved positive for the virus after using more precise PCR tests, having previously tested negative for a fast test.

But the study found that people over 65 have only 47 per cent protection against infection repetition, compared to 80 per cent youth protection.

“Our study confirmed that a number of other studies have shown that reinfectation with COVID-19 is less common among young people, healthy than in older people who are at higher risk of taking it back,” Stein Ethelberg said near the Danish Statens Serum Institute.

Because older people are more likely to have more serious symptoms of the disease, our findings make it clear how important it is to implement the elderly's defence policies during a pandemic,” says the study.

The authors of the study did not find that protection against re-influence falls within six months of the disease, but stress that further studies are needed to determine protection against re-influence in various versions of the virus.

Testing data was collected with the help of Denmark's National Test Strategy, in which 69 percent of the population, or four million people, were tested in 2020.

Commenting on the results, professors from the Royal College, Rosemary Boyton and Danny Altman, said the results show weaker protection and that they are <x0 most disturbing “” than some previous studies.
