Today I will write about a virus that is extremely dangerous for every human being. It's name Corona virus. Many people died in this virus.
early 2020, after a December 2019 outbreak in China, the World Health Organization identified SARS-CoV-2 as a new type of coronavirus. The outbreak quickly spread around the world.
COVID-19 is a disease caused by SARS-CoV-2 that can trigger what doctors call a respiratory tract infection. It can affect your upper respiratory tract (sinuses, nose, and throat) or lower respiratory tract (windpipe and lungs).
It spreads the same way other coronaviruses do, mainly through person-to-person contact. Infections range from mild to deadly
Coronaviruses (CoV) are a large family of viruses that cause illness ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV). A novel coronavirus (nCoV) is a new strain that has not been previously identified in humans.
Coronaviruses are zoonotic, meaning they are transmitted between animals and people. Detailed investigations found that SARS-CoV was transmitted from civet cats to humans and MERS-CoV from dromedary camels to humans. Several known coronaviruses are circulating in animals that have not yet infected humans.
Common signs of infection include respiratory symptoms, fever, cough, shortness of breath and breathing difficulties. In more severe cases, infection can cause pneumonia, severe acute respiratory syndrome, kidney failure and even death.
Standard recommendations to prevent infection spread include regular hand washing, covering mouth and nose when coughing and sneezing, thoroughly cooking meat and eggs. Avoid close contact with anyone showing symptoms of respiratory illness such as coughing and sneezing.
COVID-19 affects different people in different ways. Most infected people will develop mild to moderate illness and recover without hospitalization.
Most common symptoms:
mon symptomsfever
dry cough
tiredness
Less common symptoms:
aches and pains
sore throat
diarrhoea
conjunctivitis
headache
loss of taste or smell
a rash on skin, or discolouration of fingers or
How long will the coronavirus last?
There's no way to tell how long the pandemic will continue. There are many fcators, including researchers’ work to learn more about the virus, their search for a treatment, the sucess of the vaccines, and the public’s efforts to slow the spread.
UNICEF, an agency of the United Nations, offers some helpful information for teens and their parents/guardians on managing stress and anxiety about the COVID-19 pandemic.
The World Health Organization tracks global information about the COVID-19 outbreak and how countries around the world are responding
Vaccines save millions of lives each year. Vaccines work by training and preparing the body’s natural defences --- the immune system--- to recognize and fight off the viruses and bacteria they target. If the body is exposed to those disease-causing germs later, the body is immediately ready to destroy them, preventing illness.
There are currently more than 50 COVID-19 vaccine candidates in trials. WHO is working in collaboration with scientists, business, and global health organizations through the ACT Accelerator to speed up the pandemic response. When a safe and effective vaccine is found, COVAX (led by WHO, GAVI and CEPI) will facilitate the equitable access and distribution of these vaccines to protect people in all countries. People most at risk will be prioritized. While we work towards rolling out a safe and effective vaccine fairly, we must continue the essential public health actions to suppress transmission and reduce mortality.
