October 23, 2021
Coronavirus disease-19 (Corona 19, English: coronavirus disease 2019, COVID-19) or novel coronavirus infection (culture: new coronavirus infection) is a severe respiratory syndrome caused by SARS-CoV-2. The first case was reported in December 2019. As it spread around the world, it became an epidemic. Symptoms of COVID-19 vary, but include fever, cough, headache, fatigue, shortness of breath, and loss of smell and taste. Symptoms appear within 1 to 14 days of being infected with the virus. In particular, one-third of those infected are asymptomatic and do not show any noticeable symptoms. 81% of people who stand out enough to be classified as patients develop mild to severe symptoms, 14% of people develop symptoms such as shortness of breath and hypoxia, and 5% of people develop severe symptoms such as respiratory failure and shock. Occurs. Older adults are more likely to develop severe symptoms, and organ damage has been observed in some people due to COVID-19 exposure long after recovery. Investigations have been ongoing for a long time to further investigate the long-term effects of the disease. The transmission of COVID-19 occurs through breathing and droplet contact with an infected person. The probability of infection is highest when you are close to an infected person, but you can also be infected from a long distance in a room without ventilation or ventilation. Contact with objects touched by an infected person can also cause infection, but it does not contribute significantly to infection. An infected person can spread the virus up to two days before symptoms appear. Symptoms may continue for 10 days in normal cases, and 20 days in severe cases. There are several methods for diagnosing the COVID-19 virus. Standard diagnostic methods are swab detection of viral nucleic acids by real-time reverse transcription polymerase chain reaction (rRT-PCR), transcription-mediated amplification (TMA), or reverse transcription loop-mediated isothermal amplification (RT-LAMP). Preventive measures include physical or social distancing, isolation, ventilation of indoor spaces, washing hands, and wearing a mask. Recently, a vaccine has been developed and is being vaccinated. Also, misinformation was spread on the Internet, causing a lot of damage.
