The presence of this protein is helping the Asian population recover from COVID-19.
The cases of COVID-19 are declining in many countries but the ones in Asia have recorded a steady decline. The scientists were curious as to what could be the reason behind this and according to a study, a lung-protecting protein could be making a difference.
This protein is absent in the European and caucasian population and also make them more susceptible to respiratory viruses. The coronavirus variant with D614G mutation is a predominant lineage that is infecting the European and American population according to the study published in the journal Infection, Genetics and Evolution.
The deficiency of this protein in the mentioned population greatly affects the transmission of the virus and this is one of the key factors that play a role in deciding the extent of spread as well.
protein Alpha-antitrypsin (AAT) is absent across European and North American populations and that can contribute to the spread of the virus across different populations.
The social determinants and ethnicity play a crucial role in deciding which population is likely to be more affected by respiratory viruses such as SARS-CoV-2.
There are many ongoing studies that will help us understand how COVID-19 can affect various populations but the absence of this particular protein may be the reason that the Asian population is recovering well from coronavirus infection.
