Combating COVID-19: Lessons learnt particularly among developing countries and the implications

摘要

We believe COVID-19 was first identified in Wuhan, China, in December 20191-3. By 19 July 2020 there were already 14.349 million cases and over 603,000 deaths worldwide giving a case fatality ratio among confirmed cases of 4.21%4 . This includes Bangladesh with 204,525 confirmed cases by 19 July and 2618 deaths; however, recognising appreciable underreporting3-5. Since COVID-19 is principally spread through droplet infection and physical contact6 ,with an appreciable number of patients asymptomatic and currently no vaccine, current prevention strategies have centred on active testing, lockdown, closure of borders coupled with quarantining, sanitisation and social distancing.
