What is Covid-19 ?Causes ,Sign & Symptoms and Treatment

Covid-19

• Covid-19, also known as the novel coronavirus, is a highly contagious respiratory illness caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The disease was first identified in Wuhan, China in December 2019 and has since spread globally, leading to a pandemic.

Causes of Covid-19

• The SARS-CoV-2 virus is thought to have originated from bats and is transmitted to humans through close contact with infected animals. 

• Once the virus infects a human, it can then be passed from person to person through respiratory droplets that are released when an infected person talks, 

• coughs,

•  or sneezes.

•  The virus can also be contracted by touching a surface contaminated with the virus and then touching one’s mouth, 

• nose, or 
• eyes.

Signs and Symptoms of Covid-19

• The symptoms of Covid-19 can range from mild to severe and can appear 2-14 days after exposure to the virus. 

• The most common symptoms include:

• Fever or chills

• Cough

• Shortness of breath or difficulty breathing

• Fatigue

• Muscle or body aches

• Headache

• New loss of taste or smell

• Sore throat

• Congestion or runny nose

• Nausea or vomiting

• Diarrhea

• In severe cases, Covid-19 can lead to pneumonia, acute respiratory distress syndrome (ARDS), and death. People who are at a higher risk of developing severe illness include older adults, people with underlying medical conditions such as heart disease, diabetes, and lung disease, and people with weakened immune systems.

Treatment of Covid-19

• There is currently no specific treatment for Covid-19, and the best way to prevent illness is to avoid exposure to the virus. However, treatments for symptoms of Covid-19 can include over-the-counter pain relievers and fever reducers, as well as medications to relieve symptoms such as cough, congestion, and sore throat.

• In severe cases, hospitalization may be necessary and oxygen therapy may be required. In some cases, antiviral drugs or corticosteroids may be used to reduce inflammation and help with breathing difficulties.

• Vaccines for Covid-19 have been developed and are now available to the public. The vaccines have been shown to be effective in preventing severe illness, hospitalization, and death, and are considered to be a crucial tool in controlling the spread of the virus and ending the pandemic.

Prevention of Covid-19

The best way to prevent the spread of Covid-19 is to practice good hygiene habits, such as:

• Washing hands frequently with soap and water for at least 20 seconds

• Wearing a mask in public and when in close contact with others

• Covering coughs and sneezes with a tissue or elbow (not hands)

• Staying home when feeling sick

• Avoiding close contact with people who are sick

• Cleaning and disinfecting frequently touched objects and surfaces

• It is also important to get vaccinated against Covid-19 when a vaccine becomes available to you. This is especially important for people who are at a higher risk of developing severe illness and those who work in jobs that put them in close contact with others.

Conclusion

Covid-19 is a highly contagious respiratory illness that has affected millions of people globally. The virus is transmitted from person to person through respiratory droplets and can cause severe illness, hospitalization, and death, particularly in people who are older or have underlying medical conditions.
