Introduction: COVID-19 is an infectious disease caused by a newly discovered coronavirus, a type of virus known to cause respiratory infection in humans. In early 2020, a Dec 2019 outbreak in Wuhan, China, the World Health Organization identified SARS-CoV-2. SARS-CoV-2 is one of the seven types of coronaviruses .The other coronaviruses cause most of the colds that affect us during the year but are not a serious threat for healthy people. This coronavirus outbreak quickly has spread around the world According to the WHO, coronavirus has reached almost all the countries of the world within a very short time and disrupts the health services of almost all the countries. People affected with this disease around the world have crossed several crores and death tolls have reached several lakhs. Everyday many new people are getting infected and many more are facing death. Bangladesh is not also exceptional to this fact. It has got more than 5 lakhs infected and nearly 7000 people dead.
Symptoms of COVID-19: Though COVID-19 is a new disease and much about it has not been known yet, the main symptoms according to the health experts include fever, coughing, trouble breathing, fatigue, body ache, sore throat, loss of smell and taste, nausea and diarrhea etc.
Treatment of COVID Patients: Unlike the flu, a lot of people aren’t immune to the coronavirus because it is totally new. The coronavirus also appears to cause higher rates of severe illness and death than the flu. But the symptoms themselves can vary from person to person. If the patient has mild symptoms like a headache and runny nose, he has to be in a separate room from other people and has to use a separate bathroom if possible. If the patient faces trouble breathing, he needs to take medical help as soon as possible. The patient has to follow the doctor’s advice.
Coronavirus Risk Factors: All groups of people from young to old are prone to be affected with this virus. But the older the patient is, the higher he is in risk of severe illness. The patient has also a higher chance of serious illness if he has some of the health conditions. The conditions include chronic kidney disease, a weakened immune system because of an organ transplant, obesity, heart failure or coronary artery disease and type two diabetics. Besides health conditions like moderate to serious asthma, high blood pressure, liver disease, smoking habits, damaged lung tissue can lead the patient to severe COVID-19 illness and even to death.
How the Coronavirus Spreads: The coronavirus spreads from person to person. Most of all times, when an affected person coughs and sneezes, the germs of the disease spread. If the other persons breathe the droplets in or swallow them, the virus can get into their body. People with no symptoms or even little symptoms can also spread the virus. The virus can live for several hours on the surface depending on the various types of materials. Anyone can get the virus from touching the surface or object the virus is on, then touching his mouth, nose or possibly his eyes.
