Prof Nasima Sultana said exposure to enough sunlight might have played a role in contributing towards people's immune systems
Although Bangladesh is showing no sign of flattening the curve in the Covid-19 cases, the country is making strides in recovering from the deadly viral disease.
The recovery rate increased by 46% in the country within two months as it was 2.11% on May 1.
The rate now stood at 48.60% with 88,034 patients making full recovery as of July 11.
The recovery rates against the total number of Covid-19 positive cases have been going up since June.
Earlier, the rate that was below 3% in April, witnessed a change on May 3 when the health authorities reported a sudden jump in the recovery cases (1,063).
Until May 2, as many as 177 people recovered from the disease since the country detected its first coronavirus cases on March 8.
Prof Nasima Sultana, additional director general (administration) of Directorate General of Health Services (DGHS), on May 3 explained about the jump and said: "The clinical management committee has set new guidelines on determining recovered patients which, among other things, now also take into account patients who have recovered at home."
On June 1, the recovery rate stood at 21.39% and the rate almost doubled (41.61%) on the first day of July.
The country witnessed a sudden spike in recovery on June 15.
According to the health authorities, 15,297 people made full recovery on the day which is the highest in a 24-hour span till now. Since then, the recovery rate in Bangladesh remained close to 40% or above.
With no respite from the increasing trend in coronavirus cases, the country's total detections jumped to 178,443 while the number of total fatalities reached 2,275 until July 10.
Meanwhile, Bangladesh is showing a downward trend in terms of mortality rates as well. The rate is 1.27% against total cases detected so far.
On May 1, the mortality rate stood at 2.06% and it came down to 1.36% on June 1.
As per Worldometer, a reference website that provides real-time statistics for Covid-19 situation, 93% of coronavirus infected people made full recovery worldwide and 7% of them succumbed to death.
'Sun exposure probably contributing to surge of recovery rate'
On July 10, Prof Nasima Sultana told Dhaka Tribune that Bangladesh is seeing so many asymptomatic cases and cases with mild symptoms.
"Fortunately, this is the trend in Bangladesh. Most of these people are having a speedy recovery and do not need hospitalization."
She also said exposure to enough sunlight might have a role in contributing towards people's immune systems.
"People in Bangladesh are getting enough sunlight without any effort unlike many countries around the world," said Nasima, adding that getting enough sun exposure is probably contributing to the surge of recovery rate.
Recently, researchers at Trinity College Dublin, Ireland, suggested that a Vitamin D deficiency could be linked with developing a more severe case of Covid-19.
The DGHS official also said she thinks people in Bangladesh are now less panicked at this stage compared to the primary stage of the pandemic.
"People can deal with their health better when they have enough mental strength," she added.
