Q1 Gather information about the structure of corona virus (COVID-19) and mode of infection of corona virus.

Structure of Corona Virus :-
Corona virus is large in size where the cell diameter is 400-500 micron. The corona virus pa rticles are organised with long RNA(ribonucleic acid) polymers tightly packed into the centre of partical, and s and surrounded by proactive capsid , which is lattice  off repeated protein molecules referred to as coat or capsid proteins. In coronavirus , these proteins are called nucleocapsid (N). The coronavirus core particle is further surrounded by an outer membrane envelope made of lipids (fats) with proteins inserted. These membranes derived from the cells in which the virus was last assembled but are modified to contain specific viral proteins including the spike (S), membrane (M), envelope (E) proteins .
Coronavirus particles are rapidly and activated – killed – by exposure to 70% ethanol or 90% isprolanol (rubbing alcohol) , hydrogen peroxide solutions, hypochlorite bleach, soaps and detergent, as well as by UV light and the high temperatures of cookin

the upper images showing a structure of coronavirus.


Mode of infection of coronavirus :-

•Droplets or aerosols- when an infected person coughs, sneezes or talks, droplets or any particles called aerosols carry the virus into the air from their nose or mouth anyone who is within 6 feet of that person and breathe it into their lungs and he/she can get infected by virus.

Airbone transmission- virus can live in air up to 3 hours. It can get into your lungs if someone who has it reach out and you breathe the air in. Exports are divided on how open the virus spreads through the earphone route and how much it contributes to the pandemic. 


Q2-Few preventive measures to be taken by everyone each day to defeat this pandemic:-

•wash your hands of 10 with soap and water for at least 20 seconds. Use and alcohol - based hand sanitizer that contains at least 60% alcohol if soap and water are not available .

•Avoid touching your eyes nose and mouth with unwashed hands.

•Avoid close contact with people who are sick. Cover your cough was nice but that issue then through the tissue in the trash.

•Clean and disinfect frequently used objects and surfaces.

•Maintain at least 1 metre or 3 metre distance between yourself and other people,particularly those who are coughing, sneezing and have a fever.

•Wear cloth face coverings in public settings where other social distancing measures are difficult to maintain.

•Wear mask all the time when you are in crowd or with family members.

,.        AT THE LAST BUT NOT THE LEAST
            🙂 STAY HOME, STAY SAFE 🙂
