Explanation:
Currently the entire world is experiencing the desolation and
devastation of a deadly virus, the new disease of COVID-19,
emerging from the new coronavirus SARS-CoV 2, has spread
throughout the world, affecting more than 200 countries and
hundreds of people, with discouraging morbidity and mortality
figures.
All this started at the end of December 2019, specifically on the
31st, where the Chinese Disease Control Center reported 27
cases of patients with pneumonia of uncertain etiology and who
had in common a Hunan seafood market that it lacked sanitary
measures, warning of a possible zoonosis.
On January 7 its causal agent was identified, which was a
coronavirus and it was called with the name of the new
coronavirus (2019-nCoV). The researchers delimited the 2019-
nCoV sequence with that of other viruses through a database of
genetic sequences, discovering that the most related were two
viruses of Chiroptera origin as indicated by their scientific name
(bats), (bat-SL -CoVZC45 and bat-SLCoVZXC21). However, their
similarities were less than 90%, therefore, it was suggested that
there was the possibility that there was another animal reservoir
that acted as an intermediary between bats and humans. On
February 11, the WHO coined the name SARS-CoV 2 and until
March 11 it was declared by the same entity as a pandemic.
The clinical picture of patients with COVID-19 has a pattern of
respiratory dominance and depends on the tropism of the virus
towards the target organs of the body, because SARSCoV-2 uses
the ACE-2 receptor for its entry into the host cell . The virus binds
ACE-2 with an affinity 10-20 times greater than SARS-CoV. This
receptor is highly expressed in multiple body tissues, including
lung, gastrointestinal, kidney and cardiac tissue, explaining the
symptoms present in the prodrome of the disease

Answer:
Corona Virus which is commonly known as COVID-19 is an infectious disease that causes illness in the respiratory system in humans. The term Covid 19 is sort of an acronym, derived from “Novel Corona Virus Disease 2019”. Corona Virus has affected our day to day life. This pandemic has affected millions of peoples, who are either sick or are being killed due to the spread of this disease.
COVID-19 is a new virus that is impacting the whole world badly as it is spreading primarily through contact with the person. It is spread from person to person among those in close contact within 6 feet. Most of the countries have slowed down their manufacturing of the products.
Symptoms of COVID-19
The most common symptoms of this viral infection are fever, cold, cough, bone pain, and respiratory problems. Apart from these symptoms like Fatigue, Sore throat, muscle pain, loss of smell or taste can also be seen in Corona Virus patients.
Prevention of COVID-19
Thus, the emphasis is on taking extensive precautions such as extensive hygiene, regularly washing of hands with sanitizers or soap, avoidance of face-to-face interaction, social distancing, and wearing a mask, etc.
Origin of Coronavirus
Coronavirus (or COVID-19) was first identified in December 2019 in Wuhan city of China. In March 2020, the World Health Organisation (WHO) declared the Corona Virus outbreak a pandemic.
Due to Corona Virus, the Government of India under Prime Minister Narendra Modi announced nationwide lockdown for 21 days on 23 March 2020, limiting the movement of the entire 1.3 billion population of India as a preventing measure against the Coronavirus pandemic in India.
As a result, in India, all educational institutions and almost every commercial establishment had to be shut down. International, as well as intra-state travel, was banned. India suspended all tourist visas, as a majority of the confirmed cases were linked to other countries.
Thousands of migrant workers were walking across India to reunite with their families in their native places. Indian migrant workers during the COVID-19 pandemic have faced multiple hardships. With the closure of factories and workplaces due to lockdown, millions of migrant workers had to deal with the loss of income, food shortages, and uncertainty.
The various industries and sectors are affected by the cause of this disease including the pharmaceuticals industry, power sector, educational institution, tourism. This Coronavirus creates drastic effects on the daily life of citizens, as well as on the global economy.
Conclusion
All the governments, health organizations, and other authorities are continuously focusing on identifying the cases affected by the COVID-19. Healthcare professionals face lots of difficulties in maintaining the quality of healthcare these days.
With the world facing the coronavirus crisis, the pandemic has wreaked havoc and altered human lives forever. Its impact and the untoward consequences will be felt long after the virus diminishes.
Yet, in times like this, hope is a powerful healer. Mankind stands united in its struggle against the Covid 19 pandemic and life will surely triumph.
