Learn the differences between coronavirus, flu and allergy

With the arrival of this new virus, many of us have wondered what are some symptoms that indicate that it is a coronavirus and not another condition.
Being able to distinguish the difference between each of these conditions will allow us to quickly identify what is wrong with our body and know when it is necessary to see a doctor.
Something that should be clear is that the initial symptoms of COVID-19 are very similar to those of the common flu, however, as the disease progresses, we will know which one it is, either by the permanence or severity of the symptoms.
According to studies carried out by the World Health Organization (WHO), a 80% of infected people develop very mild symptoms (fever, dry cough), a 14% more severe symptoms (shortness of breath or difficulty breathing) and 14% more severe symptoms (shortness of 6% more serious illnesses (pneumonia, lung failure, organ failure and risk of death).
Here’s how you can tell the difference between each of these conditions:


It is the only one of the three conditions mentioned here that will cause muscle pain and will usually last 3 to 5 days.
As mentioned above, the flu and the coronavirus can present very similar symptoms at the beginning, with the difference that the flu presents some symptoms different from COVID-19, such as runny nose, congestion and sneezing.
The duration of symptoms is key to identifying if it is the flu.


In the case of allergies, most of them are seasonal as they usually occur in spring or autumn. Its most common symptoms are sneezing, runny nose, congestion, watery eyes, and sore or scratchy throat, but not all at the same time.
Rarely, the person will have a cough or fever. It is very easy to identify if it is an allergy because most people can tell which foods or substances cause their body to react in this way, and symptoms usually occur after exposure to the food or substance that triggers the allergy.


Among the most common symptoms developed in most of those infected we can mention fever, dry cough and constant tiredness. Other symptoms that may occur include headache, sore throat, and shortness of breath. Only 4% of cases have suffered from diarrhea.
It is important to clarify that the most vulnerable groups of people to get infected and develop serious symptoms are those over 60 years of age, people with pre-existing diseases such as hypertension, heart disease, diabetes, among others.
Coronavirus cases usually have a context, for example:
Have you recently travelled to a country where there have been many cases?
Have you been in contact with someone infected?
Did you go on a cruise?
Do you work in a hospital or health centre?
In any case, it is always recommended to use a mask, even if we only suspect it is the flu, to prevent other people from getting infected, especially the elderly. You should also follow the recommendations issued by health organizations, such as washing your hands frequently, using antibacterial gel, keeping a distance of 2-3 meters from other people and avoiding crowded places.
It is also recommended to stay home as long as possible to avoid exposure and help “flatten the curve” of the coronavirus.
It is important that in case of more severe symptoms, seek medical attention to detect early any condition that may be more serious.
