According to the Portuguese Society of Allergology and
Clinical Immunology (SPAIC) until July 7, high to very high concentrations are
expected in the regions located in the North and Centre of the country and in
the south, it will be low to moderate.
Low levels of pollen in the atmosphere and moderate levels
in the Azores are expected for the Madeira archipelago.
SPAIC adds that throughout the country, pollen grains from
grass and parietaria herbs predominate, which have a high allergenic capacity.
