How to Differentiate the Common Cold, Flu, and Allergic Rhinitis from COVID-19?

Coronavirus is a virus from the Coronaviridea family, which can cause diseases in the spectrum that can range from simple colds to severe pneumonia. Influenza (flu) virus is a virus from the Orthomyxoviridae family, which can also cause cold symptoms and lung infection. Between 30-80% of the common cold virus is Rhinovirus, which is linked to the Picornaviridea family. Allergic rhinitis is known as a disease of the inherited immune system that is completely independent of these.

These four conditions may cause a runny nose, flu, Allergic Rhinitis sore throat, cough, and mild fever in patients. However, the most common cause of cold is the common cold virus. Allergic rhinitis does not cause fever. If the person has allergy complaints (frequent sneezing, nasal itching, watery nasal discharge, cough) in the spring months and knows himself in this sense, there is no need to worry about viral diseases. However, if the complaints of the allergic rhinitis patient are accompanied by fever, intense cough, muscle pain, headache, and weakness, and if they have not experienced similar complaints in the past, they should definitely apply to the doctor for differential diagnosis of viral diseases. In allergic rhinitis, fever, intense muscle pain, and sore throat do not occur.

There is no shortness of breath in the common cold
In the common cold, sore throat, nasal congestion, again watery rhinorrhea, headache, and not very high fever are seen. There is no shortness of breath in the common cold, there is little or no muscle pain. If the person does not have any other lung problems, the disease does not go down and cause lung infection. The disease will enter into a healing process in a few days with an anesthetic medication, a little rest, and plenty of fluid intakes. The flu is a little more severe. Fever above 38 degrees, headache, intense muscle pain, and fatigue, frequent dry cough is mostly present. But nasal congestion, watery nasal discharge, or frequent sneezing is almost nonexistent. The flu virus can also cause pneumonia in the lung, which can be fatal. These four disorders, which are very similar to each other but can be distinguished by simple differences, can be diagnosed immediately with a simple quick test when necessary.


According to current information, the most common complaints in coronavirus are fever (can reach 39-40 degrees), a weakness for 2-3 weeks, muscle pain, frequent dry cough, headache, shortness of breath, inability to taste and smell. Nowadays, if there are intense headaches, fever, and coughs with the cold, it is useful to go to the hospital by following the mask, social distance, and personal hygiene rules.
