- Since the first detection of COVID-19 in China at the end of last year, it has spread to more than 200 countries and territories.
- Here's a visualization tracking its spread.
As the world continues to grapple with the disruptive impact of COVID-19, its origins remain mysterious.
Though differing accounts have been offered, what we know for certain is that the coronavirus was first detected during the final days of 2019 in Wuhan, a Chinese city of about 11 million people in Hubei province – perhaps previously best known in the West as home to the Three Gorges Dam.
Since then, confirmed cases have been reported in more than 200 countries and territories. Using data from the World Health Organization and other sources, the World Economic Forum has created a visualization tracking its spread.
What is the World Economic Forum doing about the coronavirus outbreak?
Responding to the COVID-19 pandemic requires global cooperation among governments, international organizations and the business community, which is at the centre of the World Economic Forum’s mission as the International Organization for Public-Private Cooperation.
Since its launch on 11 March, the Forum’s COVID Action Platform has brought together 1,667 stakeholders from 1,106 businesses and organizations to mitigate the risk and impact of the unprecedented global health emergency that is COVID-19.
The platform is created with the support of the World Health Organization and is open to all businesses and industry groups, as well as other stakeholders, aiming to integrate and inform joint action.
As an organization, the Forum has a track record of supporting efforts to contain epidemics. In 2017, at our Annual Meeting, the Coalition for Epidemic Preparedness Innovations (CEPI) was launched – bringing together experts from government, business, health, academia and civil society to accelerate the development of vaccines. CEPI is currently supporting the race to develop a vaccine against this strand of the coronavirus.
The WHO began issuing situation reports about a pneumonia of “unknown cause” on 21 January, when 278 of its 282 confirmed cases had been reported in China. The visualization begins by tracing the early spread of what eventually became known as COVID-19 within that country.
Below we see Hubei province quickly turn a dark red as the number of confirmed cases there reaches into the hundreds. The shading of other provinces also darkens as their number of reported cases increases. By 19 April – following a period of leveling off – there were 84,237 reported cases in China, according to Chinese government agencies.
More than 150,000 people have reportedly died as a result of COVID-19 to date. As of 21 January, there were six reported deaths, all of them in Wuhan. However, confirmed cases had already spread to three other countries in Asia.
Below we see the spread of reported COVID-19 cases throughout Asia over time (Japan’s tally includes those on a cruise ship in Japanese territorial waters). By 19 April the WHO was reporting 158,015 cases in the Western Pacific and South-East Asia regions.
It took a while for Europe to report a significant uptick in cases. As of 25 January, there were still just three confirmed in the region, all in France.
That changed quickly when the number of reported cases in Italy began to spike in late February – an increase that’s reflected below (Spain, France, Germany, and the United Kingdom have also reported sharp increases). As of 19 April, the WHO was reporting 1,122,189 European cases in total.
In the US, the first confirmed case arrived relatively early when a 35-year-old man in Washington state checked into an urgent care centre with a nagging cough on 19 January. As of 20 February the WHO was still reporting just 15 confirmed cases in the US. By 19 April, state and local agencies and hospitals in the country were reporting a total of 759,696 cases – indicated below in expanding dots centred over each affected location.
Nigeria reported the first confirmed case in sub-Saharan Africa on 28 February. South Africa, which didn’t report an initial case until 5 March, later suffered a spike that triggered a nationwide lockdown. Scientists have expressed concern that the spread of the coronavirus will wreak havoc on African countries with relatively weak and overburdened health systems. As of 19 April, the WHO was reporting 13,892 cases in the African Region.
The impact of COVID-19 has now spread across the globe, decimating stock markets, closing schools, triggering job losses and border controls, and spurring many people to stockpile food. Below we see the spread of confirmed coronavirus cases worldwide. As of 19 April, the WHO was reporting 2,241,778 cases in total.
