Patients suffering from asthma are 30 per cent less likely to contract Covid-19, according to a new research paper. Among a 37,000-strong group, Israeli experts found a higher proportion of asthma patients in the group who tested negative for coronavirus than those who tested positive. This implies many factors to do with the common lung condition are somehow neutralizing the impacts of the virus or keeping it from replicating. The study authors feel it could be due to anti-inflammatory medicine called corticosteroids, normally administered by inhalers. The team, however, maintains that asthma patients must continue their recommended medications during the pandemic.
Bronchial asthma has not been properly evaluated in coronavirus disease 2019 (Covid-19), according to the team from Tel-Aviv University in Tel-Aviv, Israel.
They observed lower Covid-19 susceptibility among people with pre-existing asthma.
Researchers suggest three main reasons for why people with asthma are less possibly to test positive for Covid-19.
Firstly, the difference could be sociological as people with pre-existing respiratory conditions, in particular, have been strongly cautioned about the dangers of exposing themselves to the virus. As a result, they are extra vigilant.
Categorically, they observed a total of 37,469 samples who were tested for Covid-19 from February to June 2020.
In all, 2,266 people, or 6 per cent of the total subjects, tested positive for the illness.
Asthma was found in 153 (6.75 per cent) of subjects in the Covid-19-positive group and in 3,388 (9.62 per cent) of the Covid-19-negative group.
Post adjustment for sex, age, smoking, and comorbidity factors, the team found a negative association of asthma with the possibility of being positive for Covid-19, with a 29 per cent difference (with an adjusted odds ratio of 0.71). Researchers believe their observation needs further replication in larger samples and with patients from other institutions. They also stressed that medical staff must continue treating asthma as per the present asthma guidelines and recommendations.
