Are there any other infections after Corona?

The corona measures not only protect against SARS-COV-2, but also against other pathogens. According to a simulation, people may be more susceptible to other infectious diseases after the removal of the corona rules. But there are also experts who consider this as a speculation.

The current hygiene and distance rules not only reduce the spread of Cowid-19, but also other infectious diseases such as flu and colds. According to a simulation study, U.S. researchers now warn that the temporary reduced contact with other pathogens could lead to people becoming more susceptible to such infections after the corona masses are lifted. Independent German experts emphasize that the work contains a lot of speculation and should not be misinterpreted.

Corona measures common in many countries, such as keeping your distance and wearing masks, are proven to protect against Cowid-19, writes the team led by epidemiologist Rachel Baker of Princeton University in the US. It. State of New Jersey in the “proceedings” of the US. It. National Academy of Sciences (“PNAS”). This also applies to other infectious diseases. “A decline in the number of cases of some respiratory pathogens has recently been observed in many locations around the world.”

Less flu

Early in late October – after the end of winter in the southern hemisphere – researchers reported in the journal The Lancet of an ancient time in flu in Australia and New Zealand. As an explanation for the phenomenon, they also referred to the corona measures such as keeping your distance, mouth and nose protection and school closures.

Becker’s team assumes that such measures and reduced contact with pathogens can later increase the susceptibility of the population to various infections. Using different models, the researchers simulated how the elimination of the corona measures could affect two seasonal pathogens: influenza A type flu viruses (IAVs) and the respiratory syncytial virus (RSV), which are respiratory diseases, especially in young children. According to her estimate, the number of RSV transmissions in the USA has fallen by around 20 percent since the introduction of the corona measures.

On this basis, the authors calculate that even short-term measures could lead to an increase in RSV infections with a delay. In the simulation for the USA and Mexico, most RSV cases would occur in winter 2021/22. The team came to similar conclusions about seasonal influenza influenza A. However, the authors themselves accept that prognosis regarding influenza waves is problematic, mainly because of the diversity of the viruses and the different effectiveness of existing vaccines.

Criticism of teaching

This is actually a weak point of the study, says the virologist Guls Gabriel of Heinrich Pette Institute in Hamburg, who is not involved in the study. “Influenza A viruses are changeable and adaptable. Virus evolution is a dynamic process that cannot be modeled.” Infectionologist Bard Zaltzberger of Regensburg University Hospital also objected that such dynamics could hardly be grasped in mathematical models: “There could be another wave of influenza, but the opposite could also happen,” says the president of the German Society. For Infection Diseases (DGI). The statements of the study are speculative. “If we kept all viruses away from us for three years, it would certainly be problematic for our immune system,” Salzberger emphasized.

However, most people would not wear a mask all the time, but only for a short time. Years of abstinence from pathogens are also unrealistic because various vaccines against SARS-COV-2 are already well developed. The virologist Gabriel warns especially against misinterpreting the results of the study as an argument against the corona measures – for example against wearing mouth and nose protection. Currently this is particularly important, also to reduce the risk of co-infection. If you are infected with influenza viruses and another pathogen, the combination would be much more serious. In addition, the main risk groups should be vaccinated against influenza. Therefore, it is important to have enough influenza vaccinations ready in the coming winters.
