The mild temperatures of the past few days and the flowering of many plants, like every year, have increased the concentration of pollen in the air, favoring i typical disorders of spring allergies. The rain of the last few hours only partially mitigates a process that has already begun. Anyone allergic knows: the pollen that circulate can cause a variety of causing eye irritation conjunctivitis, red eyes, swollen eyelids, watery eyes, nasal congestion, sneezing, continuous cough, itchy nose, eyes and mouth. If in the past these symptoms did not cause particular concern but only the annoyance (and the need) to be treated with antihistamines and cortisone, in the midst of the pandemic things change because the symptoms of allergy are, at least apparently, similar to those of the infection by SARS-CoV-2. But how do you know if you are in the presence of one or the other pathology?
Allergy: burst of sneezing and no fever
For those who suffer from these problems annually, things are quite simple because they easily recognize the typical ailments of the period having already tried them. Those who know they are allergic to pollen and at this moment accuse cough and cold should start the therapy prescribed by the allergist based on inhaled antihistamines and corticosteroids that reduce symptoms. Of course if after 4-5 days the disorders do not subside, you can think you have contracted Covid-19 with mild form, if without fever he had already explained Giorgio Walter Canonica, professor of Respiratory Medicine and Allergy at Humanitas University. IS fever is the main discriminating factor. One of the suspected symptoms of the coronavirus is fever which is absent in allergic manifestations, the allergist stressed. Furthermore the allergic rhinitis it should be more easily distinguished from viral because usually sneezing are blanks (that is, in bursts), the nose runs a lot (and this is a symptom not particularly typical of Codiv 19). However, even those who are overt allergic and manifest these symptoms after close contact with a positive case of Covid-19 must be alert and possibly undergo a swab to dispel any doubts.
The usefulness of masks
Respiratory allergies are widespread in the world and in Europe. About 1 in 4 people suffer from it and in Italy alone 20 million people are affected in more or less serious forms. Those who are allergic, to avoid coming into contact with allergens as much as possible, must remain indoors. The use of masks it can help because it helps prevent allergens, which are much larger than viruses, from reaching the airways.
Doubts at the first encounter with the allergy
The problem for those who do not know they have become allergic: pollen allergy can in fact develop at all ages and this is the period in which it is easier to confuse them with coronavirus. With coughs and colds that suggest a respiratory allergy, your doctor should be contacted who can make a diagnosis and set up a therapy. With the right drugs, allergic disorders subside in a few days while the infectious forms remain
