COVID-19 It is transferred by air from person to person.It was first observed in China(Wuhan) in Dec,2019 by Dr.Li There is no adequate symptom. Symptoms include fever, flu, shivering, fatigue, shortness of breath, severe throat infection and other respiratory problems. Symptoms may apear in a week to 24 days. Virus enters in body via nose, mouth, eyes or ears. Virus transmits DNA to normal body cells. This DNA harms and ultimately kills the normal cells of the body organs like lungs, liver, spleen and intestine. Dead cells transfer defected DNA to other normal cells and defect other cells. When immune system tries to fight against the virus, virus makes immune cells defected. In lungs, virus attacks epethelial cells (protective layer) of lungs and then attacks on alveoli. Alveoli become filled with fluid and condition become similar to pneumonia. The defected alveoli cause lack of O2 in body cells. Immune system fights against the defected cells. There are types of corona patients i.e mild, severe and critical.Mild patients may require little attention like require artificial respiration etc. They can recover in one to three weeks.Severe patients need proper attention and medical supplements. They may recover in three weeks to month. But critical patients put on artificial respiration and ventilator. Critical patients may recover or may die.In corona patients, virus may become weak but immune system also become weak that cause increase in the no. of bacteria which spread in the body (bactremia) and defect other body organs and cause ultimate death. To minimize the spread of corona virus we must do keep washing hands, drink lot of water and social distancing. In last, I must mention that Allah is sole creator of the universe. Science is changing day by day but Islam is complete religion. So,always keep praying to Allah. May Allah bless us with health and happiness. (Ameen)
