Males aged between 30 and 39 constitute the largest share of the Covid-19 patients in Bangladesh, reveals a study.
It also finds a rising trend of the asymptomatic cases in the country as the pandemic continues to rage.
The study was carried out on 1,021 people, who recovered four weeks prior to being interviewed after undergoing treatment at six hospitals. The study period was from April 1 to June 30, 2020.
The paper titled "A multi-centric, cross-sectional study on Covid-19 in Bangladesh: clinical epidemiology and short-term outcomes in recovered individuals" has recently been published in New Microbes and New Infections journal.
The research, conducted by researchers from seven academic and medical organisations in Dhaka, Chattogram and Mymensingh, found that recovered patients suffered from a number of complications, including sleep disturbance, pains and aches, weakened attention span, anxiety and depression, memory loss, and complications with mobility.
It revealed that 75 percent of the patients were males and highest 30 percent of them were aged between 30 and 39.
Dr Mustak Ibn Ayub, a co-author of the paper and a teacher of genetic engineering and biotechnology at Dhaka University, said the study is a great effort on understanding the heterogeneity among Covid patients in Bangladesh. "It shows that asymptomatic cases are on the rise in Bangladesh. It has also answered some questions of the scientists such as whether BCG vaccine has any protective effects against SARS-cov-2 infection."
The study also found that comorbid patients were more likely to experience mobility problems, weakness and problems in performing regular activities.
It revealed that among different age groups, the 20-39 cohorts showed the highest infection rate and in terms of gender, the prevalence of Covid-19 infection in males was three times more than that in females.
"The majority of the cases [62 percent] reported indirect contact with confirmed cases, whereas 48.5 percent admitted that they frequently went out of their homes before being infected and diagnosed," read the report.
It further showed that 50 percent of the respondents had come into close contact with confirmed cases and 40.6 percent had 341 Covid-19 positive family members.
"So, it can be easily concluded from this data that community transmission is very common in Bangladesh and hence social distancing and other preventive measures should be fully implemented to prevent further deterioration," said the report.
It found that half of the symptomatic novel coronavirus patients were overweight.
Dr Adnan Mannan, lead author of the paper and also a teacher of genetic engineering and biotechnology at Chittagong University, said they did not find any significant relationship between blood groups and chance of getting Covid-19.
He said novel coronavirus infection is prevalent among comorbid patients, especially diabetic, hypertensive and cardiovascular disease patients. Post-Covid complications were also found among asymptomatic patients.
