Corona-virus pandemic in The world


What is Coronavirus

Coronaviruses are a collection of related infections. That causes disease in warm-blooded and feathered creatures. In humans, coronaviruses cause respiratory infections that can be mild. For example, several cases of regular colds (among other potential causes, mainly rhinoviruses). And others that can be fatal, such as SARS, MERS, and prevention of COVID -19. Corona-virus pandemic in The world.

Side effects in different species fluctuate:

In chickens, they cause diseases of the upper respiratory tract. And in cattle and pigs – sagging colon. Vaccinations or antiviral drugs have not yet to be done to prevent or treat human from coronavirus diseases. And corona-virus-pandemic-in-the-world. So Coronavirus includes the Orthocoronavirinae subfamily in the Coronaviridae family. And that is the Nidovirales query and the Riboviria domain. They cover infections with a positive sense of the single-abandoned. RNA genome and a helical balance nucleocapsid.

The genome size of coronaviruses ranges from 27 to 34 kilobases. But the largest among the known RNA viruses. So the name coronavirus is derived from the Latin crown, which means “crown” or “radiance,”. This hints at the appearance of the trademark suggesting a crown or crown based on sunlight around virions ( particles). When they are visible when two-dimensional transmission electron microscopy due to the fact that the surface is covered with glomerular protein spikes.

Prevention of COVID -19

Discovery of COVID-19

Coronaviruses were first discovered in the 1930s. When it shows that acute respiratory . In domesticated chickens is the cause of the Infectious Bronchitis Virus (IBV). In the 1940s, two more animal coronaviruses isolate the mouse hepatitis virus (MHV). And transmissible gastroenteritis virus (TGEV). Human coronaviruses were discovered in the 1960s.  The earliest studies were from people with the common cold. Who named the human coronavirus 229E and the human coronavirus OC43.

Discovery of Corona-virus

Since then, other human coronaviruses have been identified including SARS-CoV in 2003. HCV NL63 in 2004, HKU1 in 2005, MERS-CoV in 2012, and SARS-CoV-2 in 2019. Most of them associated with serious respiratory infections.

Formation Corona-Virus:

Coronaviruses are large pleomorphic spherical particles with convex surface protrusions. The diameter of the virus particles is about 120 nm Formation Carona-Virus. And the virus envelope in electron micrographs. And it looks like a separate pair of electron-dense envelopes.

Formation of Carona-Virus

The viral membrane consists of a lipid bilayer in which the structural proteins of the membrane (M), membrane (E), and spike (S) are fixed.  A subgroup of coronaviruses (in particular, members of subgroup A of beta-coronavirus) also has a shorter skeletal surface protein called hemagglutinin esterase (HE). Formation Carona-Virus Inside the shell is a nucleocapsid, which is forms many copies of the nucleocapsid protein (N).

These are connected with a single-stranded RNA gene in the literal sense in the form of a continuous confirmation of the type of beads on a string. Corona-virus pandemic-in-the-world. The lipid bilayer membrane, membrane proteins, and nucleocapsid protect the virus when it is outside the host cell.

Prevention of COVID -19

The prevention of COVID -19, There is currently no vaccine for the prevention of coronavirus disease 2019 (COVID-19).

  • The best way to prevent the disease is to avoid contact with this virus.
  • The virus spread mainly from person to person.
  • Between people who are in close contact with each other (within about 6 feet).
  • Through respiratory droplets that form when an infected person coughs or sneezes.
  • These drops may fall into the mouth or nose of people who are nearby or possibly into the lungs.
  • Prevention of COVID -19,

Take steps to protect yourself:

Wash your hands often

  • Wash your hands often with soap and for at least 20 seconds, especially after you have been in a public place, or after you have a cold, coughing, or sneezing.Prevention of COVID -19, Coronavirus, Prevention
  • If soap and are not available, use a hand sanitizer that contains at least 60% alcohol. Cover all surfaces of your hands and rub them together until they become dry.
  • Do not touch your eyes, nose, or mouth with unwashed hands.
  • Avoid close contact with sick people.

Establish a distance between yourself and other people if COVID-19 distribute in your community. This is especially important for people who are at greater risk of getting sick.

Take steps to protect others

Stay home if you get sick

Stay at home

  • Stay home if you are sick, except for medical care. Find out what to do if you are sick.

Cover up coughing and sneezing.

Cover your mouth and nose with a tissue when you , sneeze or use the inside of your elbow.

  • Dispose of used fabrics in the bin.
  • Wash hands immediately with soap and for at least 20 seconds. If soap and are not available, wipe your hands with a hand sanitizer that contains at least 60% alcohol.
