India's Covid-19 situation remains hugely concerning, with several states continuing to see a worrying number of cases, hospitalisations and deaths, WHO chief Tedros Adhanom Ghebreyesus said on Friday, warning that the pandemic's second year will be "far more deadly" than the first for the world.

Ghebreyesus added that the WHO is responding to the Covid-19 surge in India and has shipped thousands of oxygen concentrators, tents for mobile field hospitals, masks and other medical supplies.
