Over the course of the study, approximately 60% to 70% of the population were found to be wearing face masks in crowded places and practicing frequent hand washing, implying the significance and success of awareness campaigns launched by the government against the Coronavirus pandemic.
Lastly, the study calls for increased healthcare facilities to combat a second wave Coronavirus particularly in areas with lower seropositivity rates.
Dr. Javed Usman, professor of microbiology at Army Medical College Rawalpindi, has said that the National Seroprevalence Study has affirmed that Pakistan, at the moment, is far away from achieving herd immunity.
Pakistan will be closer to herd immunity once 50% of its population develops antibodies against the Coronavirus.
While expressing apprehension, Dr. Javed Usman said that 89% of the Pakistani population will be susceptible to the Coronavirus in the case of a second wave.
