Zahidur Rahman, assistant professor at the virology department of Shaheed Shuhrawardy Medical College Hospital, said the virus spreads depending on the movement of people.
“When a carrier moves from one place to another, it spreads with him/her. We failed to contain movements since the beginning and this is why some districts became vulnerable to Covid-19,” he said.
The infected people could have been taken into isolation leading to minimised number of infection, if the authorities could ensure lockdown and conduct more and more tests, opined the virologist.
“However, we failed. Now identification of the infected has become a challenge and that is why the numbers are scaling up so frequently,” he added.
