Outdoor mould spores pollen

Outdoor mould spores (Cladosporium species, Alternaria alternata) está en el aire aquí desde june to october, pico July and August for Cladosporium, August and early September for Alternaria. Potencia alergénica: high. Sin reacción cruzada alimentaria establecida.

Esto es información de referencia, no un diagnóstico ni un plan de tratamiento. Un calendario de polen no puede decirle a qué es alérgico, y ninguna página puede declarar un alimento seguro para usted — solo la etiqueta del paquete en la mano y el clínico que conoce su historia. Cualquier cosa más allá de síntomas leves y de corta duración en boca o nariz — hinchazón que afecta la respiración o la deglución, urticaria lejos de la boca, sibilancias, vómito o desmayo — es una pregunta de emergencia, no de lectura.

Dónde crece aquí

These are not pollen at all: they are the spores of fungi living on dead plant material, and the same aerobiology traps that count pollen count them. Cladosporium is the single most abundant airborne biological particle of the northern summer, and Alternaria lives on senescing leaves, straw and crop residue, which ties it to the harvest.

Cuándo está en el aire

Spore counts build through the summer and peak far later than most people expect: Cladosporium through July and August, Alternaria in August and early September, both of them rising sharply during dry harvest weather and during grass cutting. Unlike pollen, spores are often released in larger numbers after a warm dry spell than after rain.

Cómo se siente

This is the one row on the calendar with a specific respiratory reputation: Alternaria sensitisation is repeatedly associated in the literature with more severe asthma and with asthma exacerbations, particularly in children and young adults, and particularly during high-spore late-summer weather. Symptoms often look more chest-led and less nose-led than pollen.

Con qué reacciona de forma cruzada

There is no established outdoor-mould food cross-reaction. Eating mould-ripened cheese or fermented food is a separate question from inhaling Alternaria spores, and one does not predict the other. Sensitisation to indoor moulds in a damp building is also a distinct problem with a distinct fix.

Qué ayuda de verdad

Spores are not in the CAMS pollen forecast, so no live number exists here. The practical markers are the situations rather than a figure: harvest, mowing, turning compost, handling straw or hay, working in a barn, raking wet leaves in autumn. Anyone whose asthma reliably steps up in late August should raise mould with the clinician managing it, because the treatment plan for a seasonal asthma trigger is not the same as for hay fever.

Qué se lee mal

Late-August symptoms are almost always blamed on pollen. The pollen calendar is largely finished by then except for mugwort, while spore counts are at their highest — and an autumn worsening that follows leaf raking rather than a flowering plant is a strong hint that spores rather than pollen are involved.
