Explanation: Assignment on covid-19.
<u><em>What is coronavirus?</em></u>
Coronaviruses are a family of viruses that can cause respiratory illness in humans. They are called “corona” because of crown-like spikes on the surface of the virus. Severe acute respiratory syndrome (SARS), Middle East respiratory syndrome (MERS) and the common cold are examples of coronaviruses that cause illness in humans.
<u><em>When it happened?</em></u> The new strain of coronavirus was first reported in Wuhan, China in December 2019. It has since spread to every country around the world.
<u><em>Coronaviruses come from:-</em></u> Coronaviruses are often found in bats, cats and camels. The viruses live in but don’t infect the animals. Sometimes these viruses then spread to different animal species. The viruses may change (mutate) as they transfer to other species. Eventually, the virus can jump from animal species and begin to infect humans. In the case of CoV-19, the first people infected are thought to have contracted the virus at a food market that sold meat, fish and live animals.
The virus that causes COVID-19, enters your body through your mouth, nose or eyes (directly from the airborne droplets or from the transfer of the virus from your hands to your face). It then travels to the back of your nasal passages and mucous membrane in the back of your throat. It attaches to cells there, begins to multiply and moves into lung tissue. From there, the virus can spread to other body tissues.
<u><em>Coronavirus is likely spread:</em></u>
The virus travels in respiratory droplets released into the air when an infected person coughs, sneezes, talks, sings or breathes near you. You may be infected if you inhale these droplets.
You can also get coronavirus from close contact (touching, shaking hands) with an infected person and then touching your face.
<u><em>The best way to avoid spreading COVID-19 to others is to:</em></u>
- Stay 6 feet away from others whenever possible.
- Wear a cloth mask that covers your mouth and nose when around others.
- Wash your hands often. If soap isn’t available, use a hand sanitizer that contains at least 60% alcohol.
- Avoid crowded indoor spaces. Open windows to bring in outdoor air as much as possible.
- Stay self-isolated at home if you are feeling ill with symptoms that could be COVID-19 or have a positive test for COVID-19.
- Clean and disinfect frequently touched surfaces.
COVID-19 symptoms vary from person to person. In fact, some infected people don’t develop any symptoms (asymptomatic). In general, people with COVID-19 report some of the following symptoms:
- Fever or chills.
- Cough.
- Shortness of breath or difficulty breathing.
- Tiredness.
- Muscle or body aches.
- Headaches.
- New loss of taste or smell.
- Sore throat.
- Congestion or runny nose.
