Pandemic of covid 19 (eng. Pandemic of COVID-19) is a pandemic of the 2019 coronavirus disease (COVID-19) that broke out in Wuhan, China and is characterized by respiratory tract infection and pneumonia. The epidemic was declared at the beginning of December in the city of Wuhan in central China. The disease is caused by a virus of the corona virus family called SARS-CoV-2, which represents the second spread of an infectious disease from this group of viruses after the SARS epidemic in 2002 and 2004. Human-to-human transmission of the SARS-CoV-2 virus was confirmed by the World Health Organization (WHO) on January 23, 2020, and declared a pandemic on March 11. The pandemic has affected 185 out of 193 (95.8%) member states of the United Nations (UN) and both observer states of the UN General Assembly. The infection is transmitted between people through droplets. The incubation period is usually around five days, and ranges from one to 14 days. The most common signs and symptoms are fever, dry cough, malaise, sputum production and shortness of breath. The most serious complications can be pneumonia and acute respiratory distress syndrome. Hand washing and social distancing are recommended as preventive measures. The goal of preventive measures at the population level, as part of the "flattening the curve" approach, should be to reduce the number of patients at the same time so as not to exceed the capacities of the health system. curfew and border closures. At the end of March 2020, almost a quarter of the world's population was in quarantine. Schools and universities were closed in more than 160 countries, affecting over one and a half billion pupils and students (91%) worldwide. The pandemic has led to global socioeconomic disruptions in the world. Numerous international gatherings, cultural and religious events were postponed or canceled, and the global sports calendar underwent the biggest changes since World War II. The WHO has also warned of an "infodemic" due to the frequent spread of fake news and conspiracy theories related to this disease.
