Question

describe the life cycle of covid19 in reference to lyctic and lysogenic cycle​

Answer 1

Explanation:

COVID-19 lungs

Respiratory infections such as COVID-19 start in the upper respiratory tract and, in serious cases, can move into the lower respiratory tract.

Respiratory infections are among the most common diseases that affect humans. These illnesses can range from mild colds to serious lower respiratory tract infections such as bronchitis and pneumonia.

Many respiratory infections are caused by coronaviruses, a family of viruses that are easily spread through respiratory droplets in the air and on surfaces. The novel strain COVID-19 is the cause of the current worldwide pandemic.

In some patients, moderate upper respiratory infections can progress into serious lower respiratory infections within a few weeks. Patients whose symptoms began with a mild cough may develop respiratory failure, needing ventilator support to breathe.

How can a microscopic virus wreak such havoc in the body so quickly? And why do some patients (including men) get hit harder with respiratory illnesses?

Let’s take a closer look at what happens when a respiratory virus, such as COVID-19, enters the body, as well as how we can protect ourselves and others.

COVID-19 can move from the upper to lower respiratory tract

Viral respiratory illnesses typically spread when an infected person coughs or sneezes, spraying germs into the air that land on surfaces. If you breathe in the respiratory droplets, or touch surfaces and then touch your face, the virus can enter your body and infect you.

COVID-19 is particularly contagious; one infected person, on average, spreads it to 2.2 people. By comparison, people with the seasonal flu typically spread it to about 1.3 people. The novel coronavirus also seems to infect the upper and lower respiratory tracts at a higher rate than other viruses, which creates more coughing and more potential for community spread.
