The coronavirus infection rate among the slum-dwellers in Dhaka has been found to be relatively low but many researchers have dismissed the notion they have developed immunity to the virus, bdnews24.com reports.
A survey, which ran from April 18 to July 05, had found a six per cent infection rate among the slum residents.
Six slums were included in the study conducted by the Institute of Epidemiology, Disease Control and Research and the International Centre for Diarrheal Disease Research, Bangladesh in collaboration with USAID and the Bill & Melinda Gates Foundation.
Dr Be-Nazir Ahmed, former director general of health services, said the matter cannot be ruled out and a detailed study is needed to find out the cause of the low infection rate.
The world’s largest slum in Mumbai was found to have a high infection rate but similar testing was not carried out here in Bangladesh, he said.
Asked whether slum dwellers have developed immunity to Covid-19, Ahmed said, “Some of them may have developed immunity to some diseases. But then again, they consume less nutritious food which may lead to lower immunity. So, it is very difficult to come to a conclusion.”
Mushtuq Husain, the former chief scientific officer of IEDCR0, dismissed the notion of slum-dwellers being more immune to the virus as just a thought.
A large number of slum-dwellers lost their jobs and moved to their village homes after the Covid-19 outbreak and most of them did not get tested, he said.
“Those who were living in Dhaka were working. They showed no symptoms even if they were infected. Infections will only be detected after they get tested. The survey finding of six per cent infection rate is also important and it is not a small number.”
According to Meerjady Sabrina Flora, former IEDCR director, the low infection rate found in the survey does not carry a lot of weight.
The infection rate in the slums might have been low but it is no reason to think that they are immune to the virus.
"No one is safe from Covid-19. Anyone can contract the disease. Many of us wonder whether slum-dwellers have any special immunity to the virus. I do not think so. It is not right to think like that until we have scientific evidence on our hands.”
On the contrary, due to the high population density in the slums, strict hygiene measures have to be implemented there, said Flora.
Data is being collected to find out the cause behind the low infection rate in the slums and it will take a few more days to get the complete facts, she added.
The level of awareness towards Covid-19 among slum-dwellers in Dhaka has been found to be low with few following the health rules prescribed by the health department to prevent the spread of the disease.
The residents of Bhasantek and Korail slums claim nobody has been infected by the virus or has died. Some even went so far as to say “the coronavirus does not infect slum-dwellers.”
Jasmine Akhter lives with her elderly mother in Bhasantek slum. She told the news agency that she does not know of anyone who has contracted the virus in the slum.
"There would have been corpses lying all around if the virus infected the slum residents. People are living in congested conditions and nobody is wearing masks. Just think what would have happened if Allah did not take care of us. Everything is the same as before.”
Abdul Ali, a vegetable seller living in Korail slum, said although the area is densely populated, the infection rate is low.
"Hundreds of people travel through narrow lanes without maintaining social distance but nobody has been infected with the coronavirus. Thanks to Allah for keeping us well.”
