Coronavirus Pandemic- COVID-19
The 2019–20 coronavirus pandemic is an ongoing pandemic of coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The outbreak started in Wuhan, Hubei province, China, in December 2019. The World Health Organization (WHO) declared the outbreak to be a Public Health Emergency of International Concern on 30 January 2020 and recognized it as a pandemic on 11 March 2020. As of 8 April 2020, approximately 1.45 million cases of COVID-19 have been reported in 209 countries and territories, resulting in approximately 83,600 deaths. About 308,000 people have recovered.
Common symptoms include fever, cough and shortness of breath.Complications may include pneumonia and acute respiratory distress syndrome. The time from exposure to onset of symptoms is typically around five days, but may range from two to 14 days. There is no known vaccine or specific antiviral treatment.Primary treatment is symptomatic and supportive therapy.
Recommended preventive measures include hand washing, covering one’s mouth when coughing, maintaining distance from other people, and monitoring and self-isolation for people who suspect they are infected. Authorities worldwide have responded by implementing travel restrictions, quarantines, curfews, workplace hazard controls, and facility closures.
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 193 countries, affecting approximately 99.4 percent of the world’s student population. Misinformation about the virus has spread online, and there have been incidents of xenophobia and discrimination against Chinese people, other people of East and Southeast Asian descent and appearance, and others from areas with significant virus cases. Due to reduced travel and closures of heavy industry, there have been decreased air pollution and carbon emissions, having a beneficial effect on the environment.
