Reply To: How did the Poskim deal with the Spanish Flu?

It appears that no one is addressing my specific question. During the Influenza pandemic of 1918-1919, epidemiology and infectious disease transmission were fairly well understood. While the internet and satellite communications were, of course, far in the future, telegraph, telephone, intranational cable and even early radio were available for dissemination of news and information. In the U.S., for instance, quarantine, social distancing, even wearing masks were recommended (but not required) by local and State authorities.
My question was, at that time and under those conditions, How did contemporary Poskim rule on the same issues that we have been dealing with these days, I.E. closing yeshivas and shuls, outdoor minyanim, Etc.
