A novel strain of the coronavirus (COVID-19) – a pneumonia-like respiratory illness – has come to spread rapidly across the globe ever since it first appeared in the Chinese city of Wuhan in late December 2019. The World Health Organization declared COVID-19 a pandemic on March 11, 2020.
The virus has been diagnosed in at least 114 countries, and on every continent on the planet save Antarctica. When this article was last updated, more than 145,300 cases of coronavirus had been confirmed across the globe, with a majority of the cases coming from mainland China, Italy, and Iran. It is also believed the actual number of 2019-nCoV cases is likely much higher than that reported to date.

In an effort to contain the outbreak, several countries have shut down schools, cinemas, and public attractions, apart from imposing travel bans on foreign nationals. Mass quarantines are being implemented by Italy, New Zealand, Poland, El Salvador, Ireland, and Denmark, following China’s cue.
The global mortality rate for COVID-19 currently stands at 3.4%, far higher than that of the seasonal flu which kills only about 0.1 percent of those infected. The death toll from the potentially deadly virus had crossed 5,400 on the last count, with almost 72,000 people making recoveries.
In response to this ongoing public health emergency, researchers at Johns Hopkins University (JHU), Maryland, US, have created an online dashboard to track the spread of the virus across the globe. You can bookmark this map to see live coronavirus updates.
The interactive map, which tracks the Wuhan Coronavirus in near real-time, collects suspected and confirmed case data from multiple government sources. These include the World Health Organization (WHO), the US Centers for Disease Control and Prevention (CDC), the Chinese Centre for Disease Control and Prevention (ECDC), China’s National Health Commission, and Chinese website DXY which provides regional case estimates faster than the national level reporting organizations.
“The dashboard is intended to provide the public with an understanding of the outbreak situation as it unfolds, with transparent data sources,” says Lauren Gardner, a civil engineering professor at JHU, who led the team that produced the map.

How coronavirus spreads
Health officials have determined that this novel strain of the coronavirus respiratory illness capable of spreading through human-to-human contact, droplets carried through sneezing and coughing, and germs left on inanimate objects. About one-fifth of all patients have been observed to become severely ill, ultimately leading to pneumonia and respiratory failure. Since symptoms take some time to show, health officials are also concerned that people with mild (or asymptomatic) symptoms may not be seeking medical care, and hence, all the cases are not being reported.
