Although the daily coronavirus infection rate is around 3 percent or less in the country, it is still around 5 percent in Chattogram for around a month due to people's reluctance to follow health rules, according to health officials.
On February 17, a total of 82 cases were detected out of 1,710 samples, which means, 4.79pc cases of Covid-19 were detected on that day.
The next day, 76 such cases were detected out of 1,631 samples, which is around 4.66pc. On February 19, it was 79 cases out of 1,262 samples, which is 6.25pc. From February 21 to 25, the rate was 3.13pc, 6pc, 3.86pc, 6.33pc and 5pc respectively.
Meanwhile, three people were detected with Covid-19 though they received vaccines, said the civil surgeon's office.
Dr Abdur Rob, senior consultant of medicine and head of Covid-19 ward in Chattogram General Hospital, said the number of admitted patients has increased in the ward over last few weeks.
He said around 50 beds of the 100-bed ward remained vacant even a month ago. Now almost 80pc beds are filled with patients. "We got some patients who received vaccine and got infected later," he said.
Dr Rob said people's apathy to follow heath rules was mainly responsible for further increase in Covid-19 cases in Chattogram.
"Many think they are safe once they get vaccinated but it's not true. It takes time to develop antibody in the body. Everyone should follow health rules even after receiving the vaccine," he said.
Civil Surgeon Dr Sheikh Fazle Rabbi said many are attending programmes without following health rules. They are behaving as if the pandemic is over. Some are not wearing masks in public transport, he said, adding that all these have worsen the situation.
Rabbi said 241,932 people received vaccine in Chattogram till February 25 while 369,436 have registered for vaccination.
Contacted, Prof Dr Sujat Paul, head of medicine department at Chattogram Medical College Hospital, said number of patients has also increased in their Covid-19 ward. The 100-bed ward is almost filled with patients now-a-days, he said.
"The rate of Covid-19 cases is hovering around 2.86pc on an average nationwide while it is almost double in Chattogram," he said.
He said lack of awareness among people is behind it. "If people keep showing apathy to follow health rules, number of cases will increase," he said.
Dr Paul said people still have to take the second dose of vaccine. "They will have to take it after two months of receiving the first dose. Then after two weeks, 79pc to 80pc antibody will develop in the body. Everyone should be aware of it and follow health rules," said Dr Paul, also in-charge of CMCH Covid-19 ward.
