71 percent of people in the capital Dhaka and 55 percent in Chattogram have developed antibodies for Covid-19 in their bodies, claimed International Centre for Diarrhoeal Disease Research, Bangladesh (icddr,b).

This information has been given in a virtual webinar jointly organized by Bangladesh Health Watch and icddr,b on Tuesday.

The icddr,b has conducted a study to determine the presence of Covid-19 in the blood of 3,220 people in slums and outside the slums of Dhaka and Chattogram and its possible causes from October last year to the next five months.

The study included views at the household level, blood pressure and body nutrition measurements, and blood samples. Later, the organization got this result by analyzing the samples of those 3,220 people.

The study said the rate of “antibody production” in adults and youths is almost the same. The antibody rate in females is 70.6 percent which is 66 percent in males. 35.5 percent of people who developed antibodies had mild Covid-19 symptoms.

Besides, the study found that slum-people have higher antibodies than the outside people.

The study was conducted on slum dwellers in and outside Dhaka and Chattogram.

The presence of zinc is higher in people who developed antibodies than in people who have not still developed antibodies. Studies have also shown that Covid-19 cases are “more common in people with low education, overweight, high blood pressure and diabetes”.

People with a tendency to wash their hands frequently, touch their noses and mouths less, take BCG vaccines, and have moderate physical activity have a lower incidence of Covid-19.

The study said the people with COVID had higher levels of serum zinc than those without COVID - which may associate with mild symptoms of the disease in the study participants. 

However, no effect was observed in a Covid-19 patient with vitamin-D deficiency. Rather, high levels of vitamin-D deficiency were observed in participants.

Outside the slums, the rate of Covid-19 in the blood is higher in the slums than in the lower-middle-income people. 
The icddr,b study mentioned frequent hand washing has an impact on Covid-19 prevention. The researchers said various “preventive measures” have been taken to prevent the spread of the disease among humans.
