The Covid19 pandemic is a pandemic caused by the SARS-CoV-2 virus, a disease called Covid19. The first official Chinese name of the epidemic was a new type of coronavirus epidemic incident (in Chinese: 新型 冠状 病毒 肺炎 事件, pinyin: xīnxíng guānzhuàng bìngdú fèiyán shìjiàn, in Hungarian: xinhsing kuancsuang pingtu head sicien). The first cases were discovered in December 2019 in Wuhan, China. The outbreak was declared a pandemic by the World Health Organization (WHO) on 11 March 2020.
Outbreak of the epidemic
On December 31, 2019, an outbreak of pneumonia of unknown etiology was reported by the Chinese health authorities to the World Health Organization (WHO). The diseases have been linked mainly to goods from the 'Huanan Seafood Wholesale Market', where live animals are also sold. it is also the transportation hub of the nine most important provinces in China. People with pneumonia appeared en masse in the city, for which there was no clearly identifiable cause. Singapore’s Outbreak News Today reported on January 5 that a total of 59 patients with viral pneumonia (as of January 5), including 7 critically ill patients, had been reported by health officials in Wuhan City, Hubei Province, China. The first occurrence of the new, previously unidentified - highly pathogenic coronavirus strain (SARS-CoV-2) was traced back to 17 November 2019.
Scientists suspected that an unknown animal carrying a coronavirus had infected humans with the virus in Wuhan, where the first cases were already documented in December 2019.
By the end of December, doctors already knew that strange viral cases were accumulating in the Chinese metropolis. A previously unknown beta-coronavirus was identified from patient samples, determining the genetic stock of the new virus genome.2020. On January 5, the World Health Organization (WHO) Beijing Regional Office received a notification from Wuhan of a group of patients with pneumonia of unknown cause whose clinical symptoms are primarily fever, some patients have difficulty breathing, and chest X-rays show invasive lesions in both lungs. Chinese authorities have reported that one hundred and twenty-two close relationships of patients who have been placed under medical surveillance have been identified. The number of deaths in China was already higher in early February than the total number of deaths caused by the 2003 SARS epidemic. According to data released by the European Center for Disease Prevention and Control (ECDC) on 11 February 2020, the new coronavirus disease is officially called “coronavirus disease 2019”, abbreviated to Covid19. According to an article in the British newspaper The Guardian published on February 10, the new coronavirus causes pneumonia and, in severe cases, can cause organ failure. Because it is a viral pneumonia, antibiotics have no effect. Flu medications will not work. Scientists say well-designed clinical trials and laboratory trials are needed to determine the way Covid19 spreads.
Nevertheless, Zhong Nanshan (wd), who gained a reputation as an epidemiologist in the People’s Republic of China for curbing the SARS epidemic, predicted that the causative agent of the coronavirus epidemic could disappear from China permanently by April; the specialist predicts
