Covid-19: heart complications, long-term sequelae...Is the spectrum of damage caused by reinfections sufficiently considered?

Covid-19: heart complications, long-term sequelae…Is the spectrum of damage caused by reinfections sufficiently considered?

Are people infected with Covid multiple times more at risk of complications? If the symptoms of the disease are not so severe with reinfections, experts warn of some long-term health risks.

Reinfections with Covid-19 can bring new risks of serious medical complications, hospitalization and death, this is what is recalled from a new study revealed on the National Geographic site. These results come then the Omicron BA.4 and BA.5 subvariants, now dominant, should make reinfections more frequent.

Recent research has shown that people infected with Omicron’s BA.1 subvariant produce more antibodies that enable them to later fight off the same subvariant and previously circulating variants.

But these antibodies have proven to be ineffective against variants that appear later, such as BA.4, BA.2.12.1 or even BA.5, which are all the rage at the moment. There remains the unknown sub-variant BA.2.75, the last to appear and about which we now know little, and especially about reinfection capacities.

However, each new contamination sends a risk of complications, increasing the risk of hospitalization, death and high Covid, according to preliminary data from a study carried out on patients treated in the service of – care of the United States Department of Veterans Affairs.

COVID-19 reinfections may increase the likelihood of new health problems “chest pain, abnormal heart rhythm, heart attack, inflammation of the heart.. low oxygen in blood, lung disease,..fluid around the lungs”

What is certain, reinfections usually cause less severe symptoms than the first infection. But as the National Geographic site points out, a large study that has not yet been peer-reviewed warns of the risks associated with multiple infections. This study shows that each reinfection increases the risk of mortality, hospitalization and pulmonary, cardiovascular, renal, neurological, gastrointestinal and psychiatric sequelae, in particular.

Since the study involved only American veterans (the majority of whom were elderly men), these conclusions may not be applicable to the general population, but are mainly aimed at the elderly, immunocompromised and those with health problems. . These new scientific elements, which have not yet been confirmed by their peers, nevertheless encourage caution and take measures to avoid being reinfected.
