The Corona virus continues to spread worldwide and has caused more than 130,000 deaths so far, while confirmed infections have exceeded 2 million.
Some studies indicate that about 80 percent of people infected with the virus feel mild symptoms or have no symptoms at all, but a few others may have severe symptoms.
What is this disease? What do you do to prevent yourself from getting it?
What are the symptoms?
Corona virus infects the lungs, and major symptoms are fever and persistent dry cough.
The British National Health Service says “dry cough” means crusting cough that is not accompanied by any expectoration (thick mucus).
A persistent cough means a prolonged and prolonged cough for more than an hour or three or more coughing episodes within 24 hours. If you usually have a cough, the situation may be worse than usual.
This also leads to shortness of breath, which is often described as severe chest tightness, difficulty breathing, or a feeling of suffocation.
And the person feels fever if his temperature exceeds 37.8 degrees Celsius, as this leads to a feeling of warmth, cold or tremor.
Sore throat, headache, and diarrhea were reported, as well as a loss of smell and taste.
It takes an average of five days for symptoms to start to develop, but some people develop it later. The World Health Organization says the incubation period is 14 days.
How many people did not have symptoms?
A recent study published in a British medical journal indicated that 78 percent of people with corona virus (COVID-19) show slight or no symptoms (“asymptomatic”, according to the medical designation).
The results of the study are consistent with research conducted in an Italian village that is a hotbed of disease outbreaks, and it was found that 50 percent to 75 percent of infected people are asymptomatic, but they are “a great source” of infection.
The death rate from infection with the virus appeared to be low between
(One percent to 2 percent),
But these figures may be unreliable and inaccurate due to the failure to report many cases of infection.
Thousands of people undergo treatment for HIV infection, but some of them may die from infection, so the death rate may become higher, and it can also become less if it is known that a large number of moderate infections have not been reported.
According to the data of 56 thousand patients, WHO indicates that:
80 percent have mild symptoms, such as fever and cough, and some may have pneumonia.
14 percent have severe symptoms, such as difficulty breathing and shortness of breath.
6 percent have serious diseases, such as lung failure, septic shock (sepsis), organ failure, and the risk of death.
