The RNSA recommends that allergy sufferers:

- regularly consult the pollen vigilance map on the RNSA website
- rinse your hair at night,
- ventilate at least 10 minutes a day before sunrise and after sunset,

What are the differences between the symptoms of an allergy and Covid?
The priority for allergy sufferers, despite the coronavirus epidemic, is to maintain their background treatment to better control asthma and avoid complications. Caution of do not confuse the symptoms of Covid-19 and pollen allergy. As the RNSA reminds us, the dry cough or respiratory problems linked to asthma are indeed quite similar to those of the first symptoms of Covid-19 infection, but what makes the big difference for Covid-19 is flu syndrome (pain, body aches, fever). If in doubt, do not hesitate to consult your doctor or an allergist.

The pollen produced by the flowers is composed of tiny grains used for plant reproduction. The main manifestations of pollen allergy are allergic rhinitis (or allergic rhino-conjunctivitis), also called “hay fever”. It exists three main categories of pollen : tree pollens (birch, plane tree…), grasses (wheat, oats…) and herbaceous plants (nettle, ragweed…).
In France, the main plant species responsible for allergies are:
- grasses (April to July)
- birch (April, especially in northern France)
- the cypress (February to April)
- mugwort ragweed (August, September)
What are the symptoms of a pollen allergy?
A pollen allergy is manifested by several characteristic symptoms: itchy eyes, conjunctival redness, tearing, swollen and sticky eyelids, itchy nose, sometimes stuffy and with clear and repeated discharge. The plane tree pollens which are gaining ground throughout the country at the beginning of April are slightly allergenic but the micro-needles contained in the plane tree husks are very irritating and can scratch in the throat and make you cough.
In case of symptoms, do not hesitate to consult a doctor (general practitioner, allergist), rather by teleconsultation at the moment. The practitioner may consider the passage of allergological tests (skin tests or assays of immunoglobins E or IgE) in order to confirm the diagnosis and set up a treatment aimed at relieving the symptoms.
