Out of the 116,226 cases with known outcomes in Bangladesh by 20 July 2020 mortality rate is almost 2.3% (2,668/116,226) which comparatively lower than the global averages 6.4% (612,815/9,514,219) [10, 26]. SARS-CoV-2 infection to the health professionals has been another problem for Bangladesh because there are only 93,358 MBBS doctors and 9,569 BDS doctors in the country according to the recent data of DGHS [32]. As of 18 July 2020, there were a total of 5,690 infected cases among healthcare professionals including 1,995 doctors, 1,536 nurses and 2,159 other personnel and of them, 67 doctors died from the disease [33]. Law enforcement personnel are also at risk of SARS-CoV-2 infection as they are engaged in maintaining government injunction and thus 13,316 policemen have been infected by the virus, and 53 of them have died till the 17th of July 2020. Yet 10,076 cops have already cured of the disease and returned to their respective station [34]. Rohingya refugees living in Cox’s Bazar district are also vulnerable populations to infectious disease because more than 860,000 Rohingya refugees dwell in such a congested place [35]. As of 19 July 2020, a total of 62 COVID-19 confirmed cases and 6 related deaths have been reported in Rohingya camps. But the exact cases may be more because so far only 1,288 tests have been conducted among the population [36].
