We know: loss of taste and smell is one of the common symptoms of a Covid-19 infection and can last from a few days to several weeks. If these manifestations can be debilitating, their presence can have a positive explanation: a new study published in the journal Plos One indicates that people who face the loss of taste and smell after a Covid-19 infection are more likely to develop high levels of antibodies against the virus.

According to a study carried out in 2020 by doctors from the Foch Hospital in Suresnes (Hauts-de-Seine) and the University of Mons (Belgium), “the loss of the sense of smell is a good prognostic factor in the development of a Covid”, as stated in Le Parisien by ​Dr. Jérôme Lechien, head of the Otorhinolaryngology department at Foch hospital. And for good reason: “Only 10 to 15%” of patients who had a severe form of Covid-19 suffered from loss of smell, compared to 70 to 85% among “the mildest cases”.

New work published on December 14, 2022 confirms this finding and adds that loss of taste can also be a positive sign. To achieve this result, American researchers followed 306 adults infected with the coronavirus between April and June 2020. 196 of them reported a change in smell and 195 a change in taste.

After various analyses, the researchers found that the probability of developing antibodies against the virus was 1.98 (…)
