Many Colleges and Universities across the United States of America have cancelled in-person classes and switched to teaching their courses online, as the battle against the corona-virus in that Country intensifies.


The cancellations have been focused in States that were seriously hit by the virus, including, California, New York and Washington, after it infected more than eight hundred people in the United States and killed at least twenty-eight persons.


On Tuesday, Harvard University in Cambridge, Massachusetts, asked its students not to return to campus after its spring break, which begins on Saturday, saying that it will move to virtual teaching by March twenty-third.


Columbia University, Princeton University, Stanford University, the Ohio State University, the University of Southern California and the University of Washington have all announced similar social-distancing measures.


Dozens of schools and houses of worship across the country have been closed, and conferences, sporting events and concerts cancelled in an effort to slow the spread of the virus.
