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.
On 2 February, the WHO declared there was a "massive infodemic" accompanying the outbreak and response, citing an over-abundance of reported information, accurate and false, about the virus that "makes it hard for people to find trustworthy sources and reliable guidance when they need it." The WHO stated that the high demand for timely and trustworthy information has incentivized the creation of a direct WHO 24/7 myth-busting hotline where its communication and social media teams have been monitoring and responding to misinformation through its website and social media pages.
On 25 February, the WHO declared that "the world should do more to prepare for a possible coronavirus pandemic," stating that while it was still too early to call it a pandemic, countries should nonetheless be "in a phase of preparedness." In response to a developing case of the outbreak of the coronavirus in Iran, the WHO has sent a Joint Mission Team there on the same day to assess the situation in the country.
On 28 February, WHO officials said that the coronavirus threat assessment at the global level will be raised from "high" to "very high," its highest level of alert and risk assessment. Mike Ryan, executive director of WHO’s health emergency program, warned in a statement that "This is a reality check for every government on the planet: Wake up. Get ready. This virus may be on its way and you need to be ready. You have a duty to your citizens, you have a duty to the world to be ready," urging that the right response measures could help the world avoid “the worst of it." Ryan further stated that the current data does not warrant public health officials to declare a global pandemic, saying that the declaration would mean "we’re essentially accepting that every human on the planet will be exposed to that virus."
On the 12th of April of 2020, In the 83rd situation report by the WHO, it was declared that the number of cases has reached 1,696,588 and that the death tally has surpassed the 100,000 cases with 105,952 deaths.
