Coronavirus disease (COVID-19) is an infectious disease caused by a newly discovered coronavirus. The outbreak was first identified in Wuhan, Hubei Province,China, in December 2019. TheWorld Health Organization(WHO) declared the outbreak to be a Public Health Emergency of International Concern on 30 January 2020 and recognised it as a pandemic on 11 March 2020.
Most people infected with the COVID-19 virus will experience mild to moderate respiratory illness and recover without requiring special treatment. Older people, and those with underlying medical problems like cardiovascular disease, diabetes, chronic respiratory disease, and cancer are more likely to develop serious illness.
The best way to prevent and slow down transmission is be well informed about the COVID-19 virus, the disease it causes and how it spreads. Protect yourself and others from infection by washing your hands or using an alcohol based rub frequently and not touching your face.
Efforts to prevent the virus spreading include travel restrictions, quarantines, curfews, workplace hazard controls, event postponements and cancellations, and facility closures. These include national or regional quarantines throughout the world (starting with the quarantine of Hubei), curfew measures in mainland China and South Korea, various border closures or incoming passenger restrictions, screening at airports and train stations, and outgoing passenger travel bans.
The pandemic has led to severe global socioeconomic disruption, the postponement or cancellation of sporting, religious, and cultural events, and widespread fears of supply shortages resulting in panic buying. Schools and universities have closed either on a nationwide or local basis in more than 160 countries, affecting more than 1.5 billion students. Misinformation about the virus has spread online, and there have been numerous incidents of xenophobia and discrimination against Chinese people and people of Asian descent.
