Coronavirus (COVID-19)

Coronavirus (COVID-19) disease  is an infectious disease caused by a newly discovered coronavirus. Most people infected with the COVID-19 virus will experience mild to moderate respiratory illness and recover without requiring special treatment.

The Coronavirus (COVID-19) virus spreads primarily through droplets of saliva or discharge from the nose when an infected person coughs or sneezes, so it’s important that you also practice respiratory etiquette (for example, by coughing into a flexed elbow).Older people, and those with underlying medical problems like cardiovascular disease, diabetes, chronic respiratory disease, and cancer are more likely to develop serious illness.

What is A Coronavirus?

The whole family of coronaviruses are named Coronavirus (COVID-19), because corona means crown, and this refers to the way that the virus looks under the microscope, like there is a crown on the top of the virus.

Some of them, four or five different kinds, cause common diseases among humans. Everything from the common cold to mild or moderate respiratory illnesses. Other kinds of coronaviruses affect animals, and sometimes, on rare occasions we see coronaviruses jump from animal species into the human population.

Why is This One Getting So Much Attention?

The 2019 novel coronavirus is getting a lot of attention now, because it is a new kind of coronavirus which we have not seen among humans before. The theory is that it may have jumped from an animal species into the human population, and then begun spreading.

We have seen some people that have died of this disease, and we know that there are already thousands of cases. So people are concerned, because we do not know yet exactly how serve the disease will be or how far it will spread.

How Does This Virus Spread?

When a new virus emerges, we often have to learn much more about it, and one of the things that we question is how does it transmit from person to person? We know that most respiratory viruses are spread by large droplets that come out when people cough and sneeze, and stay aloft usually for about 182 cm in front of them.

They land on surfaces, and then can also be transmitted between person to person by touching those surfaces, such as door knobs or other surfaces. Other viruses can be spread in the air and stay aloft for a longer period of time in small droplet nuclei.

Different Coronavirus (COVID-19) Vaccines:

The best COVID-19 vaccine is the first one that is available to you. Do not wait for a specific brand. All currently authorized and recommended COVID-19 vaccines: are safe, are effective, and reduce your risk of severe illness.

The Immune System- the Body’s Defense Against Infection:

To understand how COVID-19 vaccines work, it helps to first look at how our bodies fight illness. When germs, such as the virus that causes COVID-19, invade our bodies, they attack and multiply. This invasion, called an infection, is what causes illness.

Our immune system uses several tools to fight infection. Blood contains red cells, which carry oxygen to tissues and organs, and white or immune cells, which fight infection.

How Do COVID-19 Vaccines Work?

Coronavirus vaccines help our bodies develop immunity to the virus that causes COVID-19 without us having to get the illness.

Coronavirus different types of vaccines work in different ways to offer protection. But with all types of vaccines, the body is left with a supply of “memory” T-lymphocytes as well as B-lymphocytes that will remember how to fight that virus in the future.

Finally, after you are fully vaccinated against COVID-19, you may be able to start doing some things that you had stopped doing because of the pandemic. But we’re still learning how vaccines will affect the spread of COVID-19.

After you’ve been fully vaccinated against COVID-19, you should keep taking precautions in public places or when you are with unvaccinated people from more than one household.
