Nearly five months after the World Health Organization (WHO) categorised the outbreak of the novel coronavirus as a ‘pandemic’, the count of people infected by COVID-19 globally stands at 1.8 crore. The death toll from COVID-19, the disease by the virus, stands at over 7 lakh across the world as people stick to COVID-19 prevention measures.

About COVID-19
Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It was first identified in December 2019 in Wuhan, Hubei, China, and has resulted in an ongoing pandemic. The first confirmed case has been traced back to 17 November 2019 in Hubei. As of 6 August 2020, more than 18.7 million cases have been reported across 188 countries and territories, resulting in more than 706,000 deaths. More than 11.3 million people have recovered.Common symptoms include fever, cough, fatigue, shortness of breath, and loss of smell and taste. While the majority of cases result in mild symptoms, some progress to acute respiratory distress syndrome (ARDS) possibly precipitated by cytokine storm, multi-organ failure, septic shock, and blood clots. The time from exposure to onset of symptoms is typically around five days, but may range from two to fourteen days.The virus is primarily spread between people during close contact, most often via small droplets produced by coughing, sneezing, and talking. The droplets usually fall to the ground or onto surfaces rather than travelling through air over long distances. However, the transmission may also occur through smaller droplets that are able to stay suspended in the air for longer periods of time in enclosed spaces, as typical for airborne diseases. Less commonly, people may become infected by touching a contaminated surface and then touching their face. It is most contagious during the first three days after the onset of symptoms, although spread is possible before symptoms appear, and from people who do not show symptoms. The standard method of diagnosis is by real-time reverse transcription polymerase chain reaction (rRT-PCR) from a nasopharyngeal swab. Chest CT imaging may also be helpful for diagnosis in individuals where there is a high suspicion of infection based on symptoms and risk factors; however, guidelines do not recommend using CT imaging for routine screening.Recommended measures to prevent infection include frequent hand washing, maintaining physical distance from others (especially from those with symptoms), quarantine (especially for those with symptoms), covering coughs, and keeping unwashed hands away from the face. The use of cloth face coverings such as a scarf or a bandana has been recommended by health officials in public settings to minimise the risk of transmissions, with some authorities requiring their use. Health officials also stated that medical-grade face masks, such as N95 masks, should be used only by healthcare workers, first responders, and those who directly care for infected individuals.There are no vaccines nor specific antiviral treatments for COVID-19. Management involves the treatment of symptoms, supportive care, isolation, and experimental measures. The World Health Organization (WHO) declared the COVID‑19 outbreak a public health emergency of international concern (PHEIC) on 30 January 2020 and a pandemic on 11 March 2020. Local transmission of the disease has occurred in most countries across all six WHO regions.

Regularly and thoroughly clean your hands with an alcohol-based hand rub or sanitiser or wash them with soap and water. This would kill viruses that may be on your hands.

Maintain at least 2 metre (around six feet) distance between yourself and others. This is because, when someone coughs, sneezes or speaks they spray small (aerosols) from their nose or mouth which may contain the COVID-19 virus. If you are too close, you can breathe in the droplets, including the virus if the person has been infected.

Avoid touching your mouth, nose and eyes. Your hands touch many surfaces and can pick up viruses. Thus, once contaminated, hands can transfer the virus to your mouth, nose or eyes from where the virus can enter your body and infect you.

Avoid going to crowded places.

If you develop symptoms such as cough, headache and mild fever, which are linked to the COVID-19 infection, stay home and self-isolate until you recover. Contact a doctor or seek formal medical advice. .

Wear a face mask while leaving your house.
