paragraph on virus about 100 words
Answers
Answer:
A virus is the smallest type of parasite to exist, usually ranging from 0.02 to 0.3μm in size, although some viruses can be as large as 1μm.
A viral particle or virion contains a single nucleic acid (RNA or DNA) core surrounded by a protein coat and sometimes enzymes that are required to initiate viral replication. Viruses can only replicate within the cells of animals, plants, and bacteria and, as such, are referred to as obligate intracellular parasites.
Viruses are not classified according to the illnesses they cause; instead, they are grouped into different families based on whether the nucleic acid is single- or double-stranded, whether a viral envelope is present and their mode of replication.
Explanation:
Viruses that cause illness can spread from infected people to others through the air and close personal contact. This can happen when you shake hands with someone who has a cold, or touch a surface, like a doorknob, that has respiratory viruses on it, then touch your eyes, mouth, or nose.
You can help reduce your risks by practicing social distancing and taking the following steps:
Keep 6 feet away from others.
Don't shake hands.
Wash hands often with soap and water for 20 seconds. If unable, use alcohol sanitizer wipes or lotions.
Don't touch your face, nose, or mouth, especially with unwashed hands.
When sneezing or coughing, use the crook of your elbow. Tissues are also okay.
Don't share water bottles, food, towels, utensils, etc.
Frequently clean touched surfaces with household disinfectant. Leave slightly wet and allow to air dry for best disinfection.
Stay home when you are sick.
Respectfully, stay away from sick people.
Avoid going to large public venues, such as theaters or sporting events.
Practice other good health habits. Get plenty of sleep, be physically active, manage your stress, and eat nutritious foods.
Avoid social gatherings in groups of more than 10 people.
Avoid discretionary travel, shopping trips, and social visits.
Avoid eating or drinking at restaurants, bars, and food courts. Use drive-through, pick-up, or delivery options.
