Do allergic conditions increase risk of developing Long-COVID after SARS-CoV-2 infection?

Although the data as a whole from the studies suggested that individuals with asthma or rhinitis might be at increased risk of Long-COVID after SARS-CoV-2 infection, the evidence for these associations was very uncertain. Therefore, more robust epidemiological research is needed to clarify the role of allergy in the development of Long-COVID.

“We need a better, harmonized definition of what is considered Long-COVID for epidemiological studies of this sort. Regardless we will be updating our analysis once further studies have been published in the next few months,” said corresponding author Christian Apfelbacher, of the Institute of Social Medicine and Health Systems Research, in Germany.
