Allergy, cold, Covid-19? How to differentiate them

With the arrival of spring, many allergy sufferers begin their particular way of the cross of sneezing, itchy eyes, and mucus. Many others may experience the debut of a pollen allergy.

But this year, amid a pandemic and the arrival, in all likelihood, of a fourth wave of infections, allergic symptoms can become a headache by mistaking them for more typical symptoms of the coronavirus.

If we add to this that the weather is very changeable, freezing mornings and almost summer afternoons, colds can also become a cause for concern.

So, How to differentiate the symptoms of allergy, cold and Covid-19? Well from the Spanish Society of Allergology they give us some clues to understand what is happening to us. The question lies in distinguish the symptoms of each pathology and how it evolves.


• One of the most common manifestations of allergy is allergic rhinitis, which mainly produces nasal itching, often itchy eyes as well, repeated sneezing, watery nasal distillation and more or less sudden nasal congestion.

• The distinction from another pathology is easier if we are aware that we suffer from some type of allergy, especially if it is due to pollens. If we are not clear about it, we can suspect that it is an allergy if symptoms flare up when the patient is outdoors and they improve remarkably when it stays in closed places.

• In addition, the symptoms of allergic rhinitis often relieve yourself with some speed after taking antihistamines oral topics.

• It is almost certain that the patient will not have a fever, unless the rhinitis is complicated by acute sinusitis.

In the form of asthma

• In the event that allergy appears in the form of asthma, some isolated symptoms may be the dry cough and shortness of breath. Both can be confused with the initial symptoms of coronavirus infection, but it must be remembered that asthma it does not usually produce fever.

• As with rhinitis, we can assure you that it is an allergy when asthma remits when using bronchodilator treatments rescue. (salbutamol or terbutaline).


• Symptoms can start like rhinitis: with nasal congestion, runny nose, and sometimes sneezing. In general, they increase in intensity in the space of 1 to 3 days, and mucus becomes thick, greenish-yellowish. The most normal thing in this case is that the symptoms gradually subside during the next 3 or 4 days. This means that in a matter of a week we would be recovered from the cold, if not complicated by sinusitis.

• If it is not a more intense cold there is usually no high fever. A low-grade fever may appear and be accompanied by some general malaise.


• Data have shown that symptoms can be mild (similar to a mild cold). But the most common is that symptoms are more like flu: moderate to severe fever, general malaise and tiredness, dry cough, although phlegm may appear, and shortness of breath.

• The symptoms they are progressive, and from the beginning of its presentation already usually associated with the feeling of general malaise, like when we started with the flu.

In any case, before any symptoms that makes us suspect, the best thing is to reinforce prevention measures and go to our family doctor to rule out a coronavirus infection. But doing it, of course, with the necessary precautions.

Finally, allergy experts want to clarify some issues for those patients with allergies.
