When can I get infected with coronaviruses again?

However, the message that has recently spread, especially in social networks, that the risk of harm to health increases exponentially with each additional infection can be supported by the methods used in the study. don’t prove. The study compares people who are re-infected with people who are not re-infected. It is clear that those with recurrent infections are worse off than others, he writes Ruby Bhattacharyaan immunologist at Harvard Medical School, on Twitter. The study does not compare the severity of the disease to the first infection. There are several indications from other studies that it is less difficult.

The only possible conclusion from the study is that getting infected again is worse than never getting infected again, the mathematician wrote Christina BagelProfessor of Operational Research at University College London on Twitter.

The problem is less than the abstract data, but its interpretation. Of course, it is important to avoid infection, as each one can have a negative impact on overall health. This applies to any infection by any pathogen. It becomes a problem when people interpret the data of this study as indicating the coming apocalypse, Ruby Bhattacharya criticizes.

The case study on the topic of “re-infection” is getting longer, more complex, and more confusing as well. Meaning depends, for example, on the place and time period in which the study was conducted and how old the participants were or how healthy the participants were. Unfortunately, the conclusions of these studies are often misleading. Then reports appear, especially on social networks, questioning the effectiveness of vaccinations or the functioning of the human immune system as a whole. “In Scotland now in the summer of the third year of the epidemic, there are more people infected with Covid than ever before. Despite vaccination and recent BA.1/2 infection. Neither seasonality nor immunity. Not endemic. The Swiss data journalist says with a grim look. Mark Brubacher on Twitter. Bruppacher is ignoring the fact that every vaccine, and every infection in the population, helps make people more resistant to the coronavirus. This virus, which is not a monster, also carries immutable molecular building blocks against which the immune system gradually builds permanent protection.

Do frequent infections increase the risk of developing Long Covid?

Some experts sayEvery infection with the coronavirus carries an equally high risk of contracting Long Covid. As with Russian roulette, you may hit one after the first hit, the other after the third hit, or not hit either. other professionals The long-term risk of Covid is believed to be greater for unvaccinated people during the course of the first infection. Because the immune system is not well prepared for that first contact, the virus can multiply rapidly in the worst case. Now, one of the risk factors for Long Covid is the presence of a large amount of virus that burdens the body in the early stages of infection. This is lower in people who have had an infection and/or been vaccinated, because defensive cells and antibodies are already available to prevent the virus from spreading quickly.
