NEW YORK : The total death toll in the US from the novel coronavirus pandemic could hit the grim figure of 200,000 by September and expecting a dramatic decrease in COVID-19 cases in the country will be a "wishful thinking", an eminent Indian-American professor has warned.Ashish Jha, the head of Harvard's Global Health Institute, told CNN on Wednesday that he is not trying to “scare" people to stay at home rather urged everyone to wear masks, adhere to the social distancing rules and called for ramping up testing and tracing infrastructure.“Anybody who's expecting a dramatic decrease in cases is almost surely engaging in wishful thinking.
