Allergies in Chile
A common cause of seasonal allergies in Chile is exposure to pollen and mold. Lithraea Caustica, commonly called litre, a common tree in the central region of Chile may cause allergies to people. Trekkers in this area must take the necessary precautions and must be prepared with their anti-histamines.
Another potential problem for people prone to allergies is the high incidence of mold allergy due to mold spores in the air, particularly Cladosporium, the most abundant genra in our atmosphere. A research study done in Santiago, Chile in September 1996 until August 1997 proved that fungal airborne spores are present in Santiago's atmosphere all year round, with increased toxicity during the winter season.
A respiratory mold allergy is very similar to pollen allergy, both can cause coughs, sinusitis, headache, itchy, watery eyes, and may restrict breathing, especially for those afflicted with asthma. Mold allergies can also be seasonal as the concentration of molds in the air is also seasonal, and its toxicity depends on other factors like the resistance of a person's immune system, humidity in the area where the affected person works or lives in, and ventilation. A place with poor ventilation poses a serious health risk to a person who is prone to respiratory allergies.
If allergic symptoms last for more than two weeks, consult a physician. Mold allergies can induce an asthma attack, be sure you are covered by international health insurance in Chile in case of medical emergencies.
