Speaking to mediapersons on novel coronavirus disease, the United States President, Donald Trump said, “My administration is recommending that all Americans work to engage in schooling from home when possible, avoid gathering in groups of more than 10 people, avoid discretionary travel and avoid eating and drinking at bars-restaurants and public food courts. If everyone makes these critical changes, we will be able to fight. I'm pleased to report that a vaccine candidate has begun the phase-1 clinical trial, it's one of the fastest vaccine development launches in history. We're also racing to develop anti-viral therapies and other treatments, we have some promising early results.” According to reports, a total of 3,487 positive cases of coronavirus have been registered in USA so far.
