On December 31, 2019, China informed the World Health Organization of a cluster of cases of pneumonia of an unknown cause in Wuhan City in Hubei province. On January 9, 2020, the WHO issued a statement saying Chinese researchers have made “preliminary determination” of the virus as a novel coronavirus. Since then, more than 204K deaths have been reported due to COVID-19 across the world till today…. Cases have been reported from more than 180 countries, including India. Lockdowns, curfews, massive airport screenings, quarantines, and social distancing have become the norm across the globe. Coronaviruses are a large family of viruses with some causing less severe common cold to more severe diseases such as severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS). The SARS-CoV-21 is a coronavirus very similar to the one that caused SARS. Many coronaviruses are zoonotic, meaning they are transmitted from animals to humans. While the SARS coronavirus is thought to be an animal virus from an as-yet-uncertain animal reservoir, perhaps bats, that spread to other animals (civet cats) and first infected humans in the Guangdong province of southern China in 2002, the MERS coronavirus was passed on from dromedary camels to humans in Saudi Arabia in 2012. There is evidence that the SARS-CoV-2 has also been transmitted from bats
human transmissibility of the virus compared with the SARS coronavirus. “The high affinity of the 2019- nCoV S for human ACE2 may contribute to the apparent ease with which the 2019-nCoV can spread from human-to-human,” the researchers write. “Additional studies are needed to investigate this possibility.”
19 appear within two to 14 days after exposure and include fever, cough, a runny nose and difficulty in
droplets of infected people. If a person touches a surface or object that has been infected by the virus
people of all ages can be affected by the disease, people aged 80 and above are at the highest risk of dying due to COVID-19, according to case records analysed by the Disease Control and Prevention Centers in China and South Korea. Victims of the virus with pre-existing medical conditions such as cardiovascular disease and diabetes have a higher fatality rate than others. Also the rate of fatalities was relatively higher for retirees.
COVID-19 patients are those who come in with Severe Acute Respiratory Infection (SARI) who also have a history of foreign travel or close contact with another COVID-19 patient. As per the guidelines, “COVID–19 may present with mild, moderate, or severe illness; the latter includes severe pneumonia, ARDS [Acute Respiratory Distress Syndrome], sepsis and septic shock.”
transcription polymerase chain reaction test is DNA-based and can quickly tell if someone harbours the virus. In India, the government facilities to test for the virus include 52 labs belonging to the Viral
Research and Diagnostic Laboratories network of the Indian Council of Medical Research (ICMR), 10 labs
any specific treatment for suspected or confirmed COVID19 patients. No specific anti-virals are recommended for treatment of those suffering from respiratory ailment due to lack of adequate evidence from medical literature. Protecting yourself against COVID- Guidelines by the World Health Organization specify that one of the ways to reduce the risk of infection is by regularly and thoroughly cleaning one’s hands with an alcohol-based hand rub or washing them with soap and water. Regular washing becomes important as the virus tends to be viable from hours to more than a day on different surfaces that are regularly touched with hands.
with water without using soap helps reduce the amount of microbes but does not remove most of the virus and bacteria completely. Using soap, therefore, becomes far more effective in removing microbes.
envelope, thus inactivating the virus.
masks may be effective in preventing transmission of coronavirus. Therefore suggested that masks worn by healthy individuals can help prevent infection.
between yourself and anyone who is coughing or sneezing. This is because when someone coughs or sneezes they spray small liquid droplets from their nose or mouth which may contain virus. “If you are too close, you can breathe in the droplets, including the COVID-19 virus if the person coughing has the disease,” says the WHO.
surfaces. It can then transfer the virus to your eyes, nose or mouth. From there, the virus can enter your body and can make you sick.
cough or sneeze. Then dispose of the used tissue immediately. There have been several myths around the disease, like consuming more garlic, curry leaves or cow’s urine would treat or protect one from the disease.
