essay on corona virus pandemic
Answers
Hey mate here is your answer
Coronaviruses are a large family of viruses, including some that cause the common cold to some that cause major diseases such as the Severe Acute Respiratory Syndrome (SARS) and the Middle East Respiratory Syndrome (MERS).
The coronavirus (COVID-19) outbreak came to light when on December 31, 2019, China informed the World Health Organization (WHO) 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 3,000 deaths have been reported due to COVID-19 across the world. Cases have been reported from more than 80 countries, including India. The virus has acquired the ability to spread among humans, with cases of human-to-human transmissions being reported first in Vietnam and Germany.
With the overall cases worldwide rising rapidly, the WHO has declared the outbreak a global health emergency.
Answer:
The World Health Organization (WHO) has declared the new coronavirus outbreak, which originated in Wuhan, China, a pandemic. As of July 30, the global death toll surpassed 667,000 amid at least 17 million cases. Nearly 10 million people have recovered from the disease worldwide, according to the data collected by the Johns Hopkins University in the United States.
The coronavirus family causes illnesses ranging from the common cold to more severe diseases such as severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS), according to the WHO.
They circulate in animals and some can be transmitted between animals and humans. Several coronaviruses are circulating in animals that have not yet infected humans.
The new coronavirus, the seventh known to affect humans, has been named COVID-19.Common signs of infection include fever, coughing and breathing difficulties. In severe cases, it can cause pneumonia, multiple organ failure and death.
The incubation period of COVID-19 is thought to be between one and 14 days. It is contagious before symptoms appear, which is why so many people get infected.
Infected patients can be also asymptomatic, meaning they do not display any symptoms despite having the virus in their systems.
Where did it come from?
China alerted the WHO to cases of unusual pneumonia in Wuhan on December 31.
COVID-19 is thought to have originated in a seafood market where wildlife was sold illegally.
On February 7, Chinese researchers said the virus could have spread from an infected animal to humans through illegally trafficked pangolins, prized in Asia for food and medicine.
Scientists have pointed to either bats or snakes as possible sources.
