Covid-19 and asthama riskDate: 08 July 2020 Tags: Miscellaneous
A new study suggests that patients of asthma do not seem to be at increased risk of contracting COVID-19, or of more severe illness than someone who is not suffering from asthma.
While a person’s vulnerability to severe illness caused by Covid-19 increases with age, asthma sufferers tend to be younger than those with reported high-risk conditions.
While older age and certain conditions — such as heart disease, high blood pressure, COPD, diabetes, and obesity — are recognised as risk factors for the development and progression of Covid-19, the study found that people with asthma seem to be no worse affected by SARS-CoV-2 than a non-asthmatic person.
Among possible reasons, researchers proposed that because of increased attention on the effects of Covid-19 on people in vulnerable populations, those with asthma may become hyper-vigilant about personal hygiene and social distancing.
Social distancing could improve asthma control since people who are self-quarantined are also not as exposed to seasonal triggers that include allergens or respiratory viruses.
There is also evidence that people are being more attentive to taking their asthma medication during the pandemic, which can contribute to overall health.
Age-adjusted studies could help us better understand if age is a factor in explaining why asthma patients may not be at greater risk for infection.
SARS-CoV-2 infects human cells by interacting with an enzyme (ACE2) attached to the cell membranes in the lungs, arteries, heart, kidney and intestines.
This enzyme, which is increased in response to the virus, is also thought to be beneficial in clearing other respiratory viruses.
