The number of coronavirus infection cases has been declining gradually across the country, including in Dhaka, for the last one week due to the countrywide restriction on public movement since April 5.
However, health experts said the infection cases may rise further if people do not maintain health guidelines, including wearing mask and maintaining social distance and hygiene.
“The coronavirus infection rate has been declining for the last few days which may be the result of the ongoing countrywide restriction on public movement. Earlier, infection cases increased due to the people’s desperate movement without maintaining health guidelines,” Prof Dr Tahmina Shirin, Director of Institute of Epidemiology, Disease Control and Research (IEDCR), told the Daily Sun.
Responding to a question, she said the declining trend of the infection rate may continue if people maintain health guidelines properly and avoid public gathering.
According to the Directorate General of Health Services (DGHS), 2,955 new coronavirus infection cases were detected and 77 patients died in the last 24 hours till Wednesday morning.
It said the daily positivity rate has been reported 10.48 percent in the last 24 hours while the recovery rate has stood at 89.09 percent and the death rate has reached 1.50 percent in the country.
The DGHS data said the daily positivity rate earlier came down to around only 2 percent one month back after it started to fall in July last year. But after a gradual fall, the number of infection cases, the positivity rate and number of casualty started soaring again from the second week of March.
The first case of Covid-19 was detected on March 8 last year while the first death was recorded on March 18 the same year in the country.
The number of coronavirus tests and new infection case detections started to decline in the first week of July last year and the fall continued till the first week of March this year.
However, the numbers of infections and deaths started rising further from March 10 and jumped to the highest single-day cases on April 7.
According to data of the DGHS, 3,031 infection cases were reported on April 27; 3,306 on April 26; 2,922 on April 25; 2,697 on April 24; 3,629 on April 23; 4,014 on April 22; 4,280 on April 21; 4,559 on April 20; 4,271 on April 19; 3,698 on April 18; 3,473 on April 17; 4,417 on April 16; 4,192 on April 15; 5,185 on April 14; 6,028 on April 13; 7,201 on April 12; 5,819 on April 11; 5,343 on April 10; 7,462 on April 9; 6,854 on April 8; 7,626 on April 7; 7,213 on April 6; 7,075 on April 5; 7,087 on April 4; 5,863 on April 3; 6,830 on April 2 and 6,469 on April 1.
The daily positivity rate was 12.51 percent on Tuesday while it was 12.82 percent on Monday, 13.33 percent on Sunday, 13.11 percent on Saturday, 14 on Friday, 14.63 on Thursday, 15.07 on Wednesday, 16.85 on Tuesday, 17.68 on Monday and 19.06 on Sunday, it added.
Health and family welfare minister Zahid Maleque said, "The second wave has emerged as we roamed around indiscriminately, did not wear masks, and did not maintain physical distancing. If we do the same again, the third wave will make us suffer."
According to the DGHS, after the second wave of coronavirus infection hit the country, the hospitals were overwhelmed with the Covid-19 patients. The crisis of general and ICU beds was created as those beds remained hardly vacant across the country, including in Dhaka.
Amid the rise in the number of patients, the government increased the number of general beds and ICU beds in government Covid-19 dedicated hospital, in Covid-19 units of specialised hospitals and set up country’s biggest makeshift Covid-19 hospital at DNCC market with 1,200 beds in Mohakhali of the capital.
However, the pressure on general as well as ICU beds for Covid-19 patients has reduced for the last few days as the number of patients has declined across the country.
According to the data of the DGHS available till 8:00am on Wednesday, 7,972 general beds out of total 12,260 and 453 ICU beds out of total 1,069 remained vacant for the Covid-19 patients in government and private hospitals across the country, including in Dhaka.
However, the government took several initiatives to check the second wave of the coronavirus infection as it increased treatment facilities and issued an 18-point directive, including limiting public gatherings for the next two weeks, in an effort to contain the spread of the virus on March 29.
Later, the government imposed restriction on public movement since April 5 with 11-point restrictions to combat the sharp rise in Covid-19 cases. After seven days of the restriction, the government started all out restriction on public movement that will continue till May 5.
“We have to maintain health guidelines strictly and extensively to stop the further spread of the virus,” Dr Nazrul Islam, a member of National Technical Advisory Committee on Covid-19, told the Daily Sun.
