India has reported a total of three confirmed cases of coronavirus, all of them being from Kerala.

The Kerala government on Monday declared novel coronavirus epidemic as a "state calamity" with a third student testing positive for the infection in the state.

State Health Minister KK Shailaja told reporters that the government has declared the epidemic as a "state calamity" to take all necessary steps to ensure that the outbreak is effectively controlled.

Earlier, two students from the state who studied in Wuhan in China, the epicentre of the epidemic, had tested positive for the virus in Thrissur and Alappuzha.

Meanwhile, the death toll from a new coronavirus in mainland China jumped by 73 to 563 on Thursday, its third consecutive record daily rise, as experts intensified efforts to find a vaccine for a disease that has shut down Chinese cities and forced thousands more into quarantine around the world.

China's National Health Commission said another 3,694 coronavirus cases were reported throughout the country on February 5, bringing the total to 28,018.
