Today, COVID-19 is one of the most contagious human infections ever documented in history. It is caused by a mutated strain of corona viruses called SARS-CoV-2 that can affect any person of any age. However, people older than 60 who are residing in nursing homes or long-term care facilities, and those with other disease conditions are at higher risk of developing severe COVID-19 infection. With the largest infection and fatality rate, COVID-19 was declared as a global pandemic by the World Health Organization on 11 March 2020.

Symptoms of Covid-19 infection:

A variety of clinical presentations, from no symptoms to life-threatening illnesses, can occur in patients with SARS-CoV-2 infection. The severity for adults infected with SARS-CoV-2 can generally be seperated into the following groups. However, certain information can transform according to the reports of most current epidemiological studies.

● Asymptomatic SARS-CoV-2 infection: It includes patients who are tested positive for SARS-Cov-2 during rapid antigen test or RT-qPCR. However, they have no symptoms of COVID-19.
● Mild infection: Includes ...
... patients that exhibit any of the COVID-positive symptoms such as fever, cough, sore throat, malaise, headache, muscle pain, nausea, vomiting, diarrhea, and loss of taste and smell).
● Moderate infection: It includes patients who tested positive for COVID-19 with oxygen saturation (SpO2) of less than 94 % in room air and who exhibit signs of lower respiratory problems during clinical evaluation or chest X-ray.
● Severe infection: It includes patients who tested positive for COVID-19 with SpO2 levels below 94% in room air with arterial PaO2/FiO2 ratios below 300 mm Hg, respiratory rates above 30 breaths per minute, or lung infiltration levels above 50%.
● Critical infection: It describes patients who exhibit multiple organ malfunctioning, septic shock, and/or respiratory failure.
