Antibody tests showed that 45 percent of people in Dhaka were infected with corona. At the same time, 74 per cent of people have been affected in the slums of Dhaka. In other words, 45 percent of Dhaka’s population has already produced antibodies. On the other hand, 64% of the people from Dhaka’s slums have antibodies in their body. And antibodies are produced in their bodies, which are already infected with covid.
This information emerged in a joint study on corona surveillance for the first time in the country. The study was conducted jointly by the National Institute of Disease Control, Pathology and Research (IEDCR) and the International Center for Diarrhea Research of Bangladesh (ICDDR, B).
So is Bangladesh moving towards tough crown immunity? Such a question has arisen. Although coronary heart disease is rare in slums, research shows that 84 percent of slum dwellers have antibodies. Experts believe that strong immunity has been created in the slums, though not across the country.
By the way, harsh immunity is a kind of indirect protection against infectious diseases. It forms when 60 to 70 percent of the population can prevent infection.
The lead investigator said. Ferdous Qadri said: ‘Antibody rates are increasing among the people of Dhaka. And that signals the beginning of tough immunity. The Corona prevalence rate cannot be mixed with seroprevalence data. The coroner’s prevalence rate may be higher.
In response to a question, he said: ‘Using the seroprivance rate, it was not possible to predict when the second corona wave would come. Antibodies have been around for a very short time and we’ve also seen a second infection in some people. ‘
According to another survey conducted in the program, 9.7 percent of people in Dhaka are infected with corona, but the infection rate in the slums is 5.6 percent. “Most of them have no symptoms,” he said in response to a question about low levels of antibodies and infections among slum dwellers. But that does not mean that a small number of people have been infected.
If you want to know about the program, the Scientific Director of the Institute of Pathology, Control and Disease Research (IEDCR) Dr. ASM Alamgir said: “We need to do a more detailed investigation on the seropositivity that I am seeing. It is difficult to come to a conclusion with the number of sample tests. Very soon I will start this work in the slum area. At the national level, by comparing the information we have collected from all the districts with the current one, we will be able to establish a figure at the national level. The results of the study that have been reported today are preliminary data where very few samples have been collected. It will be very difficult to decide whether Bangladesh is on the road to tough immunity.
However, former Vice Chancellor of Bangabandhu Sheikh Mujib Medical University and member of the National Advisory Committee on Covid-19, Professor Dr. Nazrul Islam said: “When 80 percent of the population is infected, a strong immunity. Since 64% of antibodies are found in the slums, a tough immunity has been built there. Although the infection rate in the slums is five point six percent. However, more research is needed here.
He added: ‘The advantage of hard immunity is that if it is manufactured somewhere, the level of infection does not increase even if the infected person goes there. Now if the infected person goes to the slum, the infection rate will not increase there.
IEDCR adviser Dr. M Mushtaq Hossain said: “The population of the neighborhood is more or less, but if antibodies are produced among those who are there, then a harsh immunity is created in the neighborhood. Since the PCR test is lower in the slums, the infection is also lower. Antibodies stay in a person’s body for up to three months. If this survey was conducted in July, the antibodies are still present. After three months of investigation, we have to do another investigation to see if there are antibodies.
It should be noted that fewer antibodies have been produced in the slums of Mumbai, India, than in Dhaka. Surveys conducted in the three slums of Chimbur, Matunga and Daisar have shown that only 56% of the population have developed antibodies against SARS COV-2. At least 1.5 million people live in these areas. Samples of 6,000 people in the country were analyzed in early July. This information is available from there. Sweden fails to achieve tough immunity. Sweden is the only country that allows the spread of the crown to create strong immunity. But that plan failed. The Swedish government estimated that 40 percent of people in Stockholm would be infected with corona and that the antibodies would be produced in May. But an August study found that only 15 percent of the crown was infected.
