Coronavirus disease 2019 Symptoms

COVID-19 is also known as Wuhan virus 2019, is a type of infectious disease caused by the 2019 Novel Coronavirus (SARS-CoV-2). The disease was first detected in China's Wuhan city in 2019. However, by then it had spread throughout the world, resulting in the 2019–20 Wuhan coronavirus epidemic.

Public Prediction
According to some people, this is a trade war by China globally. Common symptoms include fever, cough, and shortness of breath. Muscle pain, sputum formation and sore throat have also been observed in some cases. In most cases there are only mild symptoms and only in some cases can they progress to pneumonia or failure of many organs. The percentage of deaths per person in the cases being investigated is 3.4%, in which the age and health of the person vary. Currently Italy, Spain, and the United States are its main victims.

Symptoms
A person infected with this virus may have no symptoms of any kind or may experience some flu-like symptoms, including fever, cough, fatigue, and shortness of breath. Symptoms that cause some emergency situations include shortness of breath, pain or pressure in the cinematography, confusion, difficulty waking up, and burning of face or lips. If such symptoms appear, get yourself checked immediately. Some of the less common symptoms are sneezing, runny nose, sore throat. Symptoms like nausea, vomiting and diarrhea have also been shown in some people. Chest tightness and malaise were seen in some cases in China. In some cases in which there were no other symptoms, they could not smell, or they could not recognize the taste. In some cases, the disease progresses to pneumonia or failure of multiple organs and leads to death. People who had severe symptoms that required mechanical ventilation took about 8 days to show this symptom.

Caused reason
The disease is caused by a virus called SARS-CoV-2, formerly known as 2019 Novel Coronavirus (2019-nCoV). It mainly spreads in people with drops coming out during cough and sneeze. A study investigating virus decay showed that they did not appear after 4 hours on copper, 24 hours on cardboard, 72 hours on stainless steel, and 72 hours on plastic. However the detection rate of those viruses was not 100% and it varied on different surface. (Detection limits were 3.33 × 100.5 TCID50 per liter for aerosols, 100.5 TCID50 per milliliter for plastic, steel and cardboard, and 101.5 TCID50 per milliliter for copper. Estimation of the rate of decay with Bayesian regression models suggests that The virus can live up to 18 hours in copper, 55 hours on cardboard, 90 hours on stainless steel, and 100 hours on plastic. During the 3-hour experiment it was visible throughout the aerosol. The virus has also been found in feces, and its transmission through it is still being researched.

Prevention
Because vaccines that work against SARS-CoV-2 are unlikely to arrive before 2021, an important part of the management of the pandemic is attempting to stop its progression. Due to which adequate medical and medical equipment can be available for treatment. At the same time, medical service providers do not have to work excessively and get adequate time to treat and manufacture vaccines.

Taking preventive measures reduces the chances of becoming infected. Other measures to avoid infection can be used for other coronaviruses:

As much as possible, stay home and avoid traveling or doing public work.

Wash your hands often with soap and warm water.

Do not touch your eyes, nose and mouth without washing your hands.

Apart from this, keeping distance from the society is also a good strategy, which can prevent large numbers of people from coming into contact with an infected person. For this, closure of schools and offices, banning travel and not allowing any type of crowd to gather are the main measures.

According to the WHO, the mask should be used only for those who have a cough or cold or who are taking care of someone who is suspected to have the disease.

According to the advice of the CDC and the United Nations, to prevent infection, all people should stay at home and go out only for treatment. Before going to a medical institution, make a call and go to a place where there is a risk of infection, then wear a face mask. If you have a cold or cough, use a handkerchief or tissue paper and wash your hands thoroughly with soap and water. The CDC recommends that people wash their hands with soap or hand wash for at least 20 seconds. Especially after going to the toilet or after showing dirty hands and eating food or after cleaning the nose. If soap and water are not available, use hand sanitizer containing alcohol, which contains at least 60% alcohol. The WHO recommends that all people avoid touching their eyes, nose and mouth with dirty hands and also avoid getting smacked in public places.
