Since the start of the global pandemic, researchers have been racing to figure out who is most at risk from SARS-CoV-2, and why.
Researchers then tracked the spread of SARS-CoV-2 in participant households from May 2020 to February 2021., but they also didn't seem to be any more protected.Not all forms of asthma are atopic , and previoushave shown that only those with atopic asthma express lower airway levels of the ACE2 receptor, which is what SARS-CoV-2 attaches to.
Something similar could be occurring among people with food allergies, although the authors only looked at SARS-CoV-2 infection, and not the severity of the infection. Interestingly, while some studies suggest allergic asthma protects from severe cases of COVID-19, the current study found the condition does not protect from the initial contraction of the virus.
