About COVID-19

COVID-19 stems from coronavirus. Other viruses that we may know of are the common cold, chickenpox, or influenza. The scientific name of COVID-19 is SARS-CoV-2. It is believed that SARS-CoV-2 originated in bats or pangolins. The origin of this global pandemic is believed to be the wet market in Wuhan, China, but governments and the United Nations continue to investigate this.

It is believed that the transfer of SARS-CoV-2 from bats to humans led to its transmission, resulting in a health crisis that took form of a global pandemic in 2020. COVID-19 can spread easily from person to person, especially if there is close contact. It can be transferred through respiratory droplets, which occur when a person sneezes, talks, or breaths. Once a person inhales infected respiratory droplets, the chances of infection multiply.

Recently, reports about it being airborne have also made rounds. Even if there is no close contact between persons, droplets can stay suspended in air, especially in a closed space. The symptoms of Covid-19 range from shortness of breath, fever, loss of smell and taste, and cough couipled with severe body aches and pneumonia.

Variants

COVID-19 and its Mutants

As the pandemic progressed, different variants and mutants of COVID-19 have surfaced. The mutants affect its transmissibility and the severity of symptoms. According to the WHO website, the following mutations have been recorded:

Apart from these known mutations, the one currently in India is the Triple Mutant. It emerged from two mutations known as E484Q and L452R.
The E484Q mutation was found in the variants that emerged in South Africa. At the same time, the L452R mutation was found in the United States variant.
Triple Mutant is found to be an immune escape variant, which makes it more infective.

Conclusion

In the End

With the rising death toll in India and the ongoing pandemic, health guidelines issued by respective local authorities should be implemented and followed. Tbe best method of prevention remains to wear face masks, maintain 2-meters distance between others, wash hands often, and remain vigilant, avoiding large groups whenever possible.
