Coronavirus (976) Effect of intermittent Lockdown in containing the spread of the tranamission of COVID Virus (5)

11 September, 2020

Dear Gladstone, I should thank your for your effort in gathering so much by doing a extensive literature to find evidence supporting references, but the basic question remains unanswered, whether intermittent lock down with periodic and or nonperiod and unplanned imposing of lock down has any effect on the transmission of coronavirus during epidemic.

1. A draft memorandun drafted by the scientists belonging to Indian Association of Public Health, Indian Association of Preventive Medicine, Indian Association of Epidemiologists, have said that partial or intermittent lock downs imposed is of no use in containing the spread of the virus in the community.

2. The gists of the other references that you have cited, is the imposing of the intermittent lock downs only delays the occurrence of second /third peaks of the epidemic with certain flattening of the peak of the curve.

In the references, you didn't mention about any study how much behavioral changes, has been the accepted by the Indian population i.e. how many of the populace is wearing masks prpoerly, what types of masks they use and how many of them are really protective against transmission of coronavirus and to what extent, how much social distancing is maintained in the markets during unlocked period or days.

I understand replying to these questions is most difficult and that is the reason, I am throwing these questions open to the distinguished members of HIFA, if they can show evidence based replies to the questions.

If sufficient data are not available, then pilot studies need to be done as early as possible. Corona infection and pandemic is a new challenge for the human race. Very less is known today about the infection. Much more to be found out by the scientists all over the world. Behavioral aspect of man is one aspect to study cricially. With no effective vaccine against the infection or simple and fully effective treatment modalities available till now, behavioral change is the only "vaccine" available to us at this point of time.
