The Coronavirus Pandemic 2019– or COVID-19 Pandemic is a pandemic that began in December 2019 in the Chinese city of Wuhan. It is caused by a new coronavirus, SARS-CoV-2, which causes a disease called COVID-19. COVID-19 has been defined as a communicable disease in Finland. The World Health Organization declared the epidemic a pandemic on 11 March 2020. The virus is believed to spread to most of the world's population.17. by August 2021, the infection had been confirmed in more than 208 million people. More than 4.3 million people had died of the disease caused by the virus. An estimated 187 million people had recovered from the disease. Western countries were ill-prepared for a pandemic. Many East Asian countries responded to the pandemic fairly quickly because they had experience with SARS and MERS epidemics. The efforts of several Western countries to slow the spread of the disease were initially protracted and shaky. The pandemic was reflected in healthcare in many countries in large numbers of patients and a lack of protective equipment and ventilators, which has increased mortality. Health care in many countries was overloaded. In March, due to the coronavirus pandemic, several countries took containment measures aimed at slowing down the progression of the disease. Schools, sports competitions, restaurants and rallies were closed and travel bans were imposed on and within countries, and people became unemployed. In many places, people avoided unnecessary street traffic in cities. Some are trying to move the pandemic to escape to the countryside or elsewhere in isolation. There was disregard for the risk of the disease spreading. In March, due to the containment measures, the economies of the societies contracted sharply, leading to opposition to the embargoes in some countries. The opening of the closures was believed to lead to an exacerbation of the epidemics. In April-May 2020, the epidemic seemed to be fading in many places. The situation was still bad in many countries. New waves of disease were predicted. In the United States, for example, the disease began to spread more strongly again, with new clusters of infection in many countries. In September-October, the epidemic worsened in many European countries. It led to many local restrictions. These were protested in some countries by riots and demonstrations. During the pandemic, the deterioration of the virus or the disease caused by it has also been assessed. In early June 2020, two Italian doctors estimated that the virus had lost its potency and become less intense in recent months.

Coronavirus

SARS-CoV-2 is also known by the former names 2019-nCo virus (abbreviation 2019-nCoV, eng. 2019-novel Coronavirus, 2019 new coronavirus). SARS-CoV-2 is the seventh known human infectious coronavirus. Others have been SARS-causing SARS-CoV and MERS-causing MERS-CoV as well as HCoV-OC43, HCoV-229E, HCoV-NL63 and HCoV-HKU1.

Mortality

There is no cure for the disease. According to the cases tested in China, about 80 percent of cases are mild. COVID-19 develops severe lung symptoms in about 14% of cases and a critical condition in about 5%. On the other hand, in Italy, for example, 16% of COVID-19 patients admitted to hospital have required intensive care. The disease is most dangerous to the elderly and the long-term, but can cause severe symptoms or death in young adults as well. In Wuhan, the casual mortality rate was 3.6 percent, according to a publication in early March. The case mortality rate for those tested in Italy was around 9% at the end of March, but rose to 12% as the course of the disease progressed (5 April 2020), while the proportion of the population tested remained still limited. These readings are based on raw data including only tested cases. The WHO estimates on 19 March that the mortality rate from the coronavirus is around 0.3% to 1.0%
