Covid infections lower in people with food allergies – and not higher in asthmatics, study finds

Asthma machine and some prescribed pills for people who suffer from asthma. An analysis by researchers in the US found no association between Covid-19 infection risk and asthma.People with food allergies are less likely to be infected with the virus that causes Covid-19 and those with asthma do not necessarily have a higher risk of infection, a study in the US has found.

The participants were drawn from NIH-funded studies focused on allergic diseases from 12 US cities and provided nasal swabs every two weeks between May 2020 and February 2021. The analysis found no association between infection risk and asthma in children, adults or the obese. Infected households with asthmatic individuals were not at increased risk of transmission, the study found.

They speculated that a specific type of immune response common in people with food allergies might reduce levels of Angiotensin-Converting Enzyme 2 - the main receptor for the virus - in the airway, lowering the risk of infection. For every year of increase in the average age of children and teenagers within a household, there was a seven per cent increase in household infection risk. In contrast, every five-year increase in average age of household carers was associated with a 14 per cent decrease in household infection risk.
