Manipur has reported its first case of coronavirus with a 23-year-old woman who returned from the United Kingdom testing positive, making it the first case in the northeast. She is a student in the UK and had flown to Delhi on March 19 and then to Kolkata and Agartala before reaching Manipur. Nearly all of India - with 32 states and union territories covering 560 districts - are under a complete lockdown to contain the rapid spread of the novel coronavirus or COVID-19. 496 people have tested positive for the virus in the country and nine have died. As reports of infection came in from all the key states, the centre on Monday tightened its clampdown with a ban on domestic flights from tonight and warned of legal action against those violating the lockdown rules. Prime Minister Narendra Modi will address the nation today at 8 pm, his second address since last Thursday when he called for a "Janata Curfew" or self-quarantine on Sunday.
