On 23 January 2020, the number of reported confirmed cases of 2019-nCoV has increased by 267 cases since the last situation report published on 22 January 2020. As of 23 January, China reported cases in 25 provinces (autonomous regions and municipalities). Twenty-five percent of confirmed cases reported by China have been classified by Chinese health authorities as seriously ill (from Wubei Province: (16% severely ill, 5% critically ill, and 4% having died).
On the 29th of Jan, the WHO confirmed that the number of infected cases has dramatically increased to reach 6065 cases globally over 98% of them are in China and the rest are spread over 15 countries, and 132 death case.
Citing 7736 cases essentially in China and 82 cases abroad across 18 countries as of 30 January, the World Health Organization declared the novel coronavirus outbreak to be a Public Health Emergency of International Concern on 30 January.
On 30 January 2020, following confirmation of human-to-human transmission outside of China and the increase in number of cases in other countries, the WHO declared the outbreak a Public Health Emergency of International Concern (PHEIC), the sixth PHEIC since the measure was first invoked during the 2009 Swine flu pandemic. Tedros clarified that the PHEIC, in this case, was "not a vote of no confidence in China", but because of the risk of global spread, especially to low- and middle-income countries without robust health systems.
