The SARS-CoV-2 virus causes COVID-19. COVID-19 has the potential to cause mild to severe respiratory illness, including death. Getting vaccinated, wearing a mask during times of high transmission, keeping 6 feet apart, washing hands frequently, and avoiding sick people are the best preventive measures. In this article we discuss regarding the Outbreak, Impact and Prevention of Coronavirus (COVID-19) which will be helpful for UPSC exam preparation.

Origin of Coronavirus (COVID-19)

• Coronaviruses are frequently discovered in bats, cats, and camels.
• The viruses live in the animals but do not infect them. These viruses can then spread to other animal species.
• Viruses may change (mutate) as they spread to new species. The virus can eventually jump between animal species and infect humans.
• The first people infected with SARS-CoV-19 are thought to have contracted the virus at a food market that sold meat, fish, and live animals.
• The first known case of COVID-19 was reported in December 2019 in the Chinese city of Wuhan and was traced to the city's animal market.

Transmission of Coronavirus (COVID-19)

• The virus that causes COVID-19, SARS-CoV-2, enters your body through your mouth, nose, or eyes (directly from airborne droplets or through virus transfer from your hands to your face).
• It then moves to the back of your nasal passages and the mucous membrane in your throat.
• It attaches to the cells, multiplies, and moves into the lung tissue. The virus can then spread to other body tissues.
• When an infected person coughs, sneezes, talks, sings, or breathes near you, respiratory droplets are released into the air, allowing the virus to spread. If you inhale these droplets, you could become infected.
• Close contact (touching, shaking hands) with an infected person and then touching your face is another way to contract coronavirus.
• The basic reproduction number (R_0) is a transmissibility metric that attempts to describe the average number of people infected by a new case.
• WHO estimates R_0 = 1.4 to 2.5 for COVID-19. Many researchers, however, believe that this figure is understated.

Symptoms of Coronavirus (COVID-19)

• COVID-19 has different effects on different people. The majority of infected people will develop mild to moderate illness and recover without the need for hospitalisation.
• People who have mild symptoms but are otherwise healthy should manage them at home.
• The average time for symptoms to appear after being infected with the virus is 5-6 days, but it can take up to 14 days.

Prevention of Coronavirus (COVID-19)

Do the following to avoid infection and slow the spread of COVID-19:

• When a vaccine is available, get vaccinated.
• Even if they don't appear to be sick, keep at least one metre apart.
• When physical separation is not possible or when the environment is poorly ventilated, wear a properly fitted mask.
• Open, well-ventilated spaces are preferable to closed ones. If you are indoors, open a window.
• Hands should be washed with soap and water on a regular basis, or cleaned with an alcohol-based hand rub.
• When coughing or sneezing, cover your mouth and nose.
• Stay at home and isolate yourself until you feel better.

Global Impact of Coronavirus (COVID-19)

Economic Impact

• The Coronavirus 2019 has had a significant impact on the global supply chain.
• The emergence of COVID-19 coincides with a slowing Chinese economy, increased trade, and tariff-related tensions.
• China is the world's largest exporter of intermediate manufactured goods, and economies that rely on Chinese imports will be impacted.
• Wuhan, for example, is home to hundreds of automotive, hardware, electrical equipment, consumer products, and other industries that serve many major manufacturers whose connections to the global supply chain have now been severed.
• China accounts for approximately 17% of global GDP and is the largest trading partner for the majority of its neighbours. China-dependent economies will be hit the hardest.
• Regardless of the impact on the supply chain, other industries such as airlines and tourism are directly impacted.
• Markets around the world have reacted negatively, raising fears of a global recession.
• The 2003 SARS pandemic is estimated to have cost the global economy $40 billion.
• COVID-19 will have a greater impact because China's share of global GDP has quadrupled since then.
• According to some economists, the expected annual losses from pandemic risk are around $500 billion per year, accounting for both lost income and the intrinsic cost of increased mortality.

Political Impact

• The COVID-19 incident has sparked public outrage at the Chinese authorities' initial cover-up attempts.
• Following the initial phase, authoritarian attempts to halt the disease, the use of high-tech surveillance, mass quarantine camps, and a state of lockdown have raised questions about the balance between citizens' freedom and dealing with a serious national problem.
• The impact of the crisis on the legitimacy of Chinese President Xi Jinping and the reputation of the Communist Party of China will be measured. This episode, however, has revealed a systemic flaw in China's top-down model.

Social Impact

• Direct health consequences for infected people can be disastrous. Pandemics have a disproportionately greater impact on young people.
• Due to panic buying and hoarding, there is a shortage of protective equipment and other necessities.
• Increased burden on health-care infrastructure and a lack of access to routine health-care services.
• Rapid population movement caused by large-scale disease outbreaks can be destabilising. Migration also increases the risk of disease spread.
• Infectious disease outbreaks can further stigmatise already vulnerable social groups and exacerbate existing social inequalities.
• The spread of rumours and misinformation, aided and accelerated by social media, makes it more difficult for people to find trustworthy information.
• People in lockdown have a negative social impact.

Conclusion

Being well informed about the disease and how the virus spreads is the best way to prevent and slow down transmission. Stay at least one metre apart from others, wear a properly fitted mask, and wash your hands or use an alcohol-based rub frequently to protect yourself and others from infection. A coordinated strategy between the central and state governments is required to deal with future epidemics.
