BACKGROUND

Current military operations in the Middle East involve active duty, National Guard, and reserve troops from all services. Despite common misconceptions, the desert environment in this region has significant aeroallergen seasons that may exacerbate allergic rhinitis.

OBJECTIVE

To review perennial and seasonal aeroallergen trends in the Middle East.

RESULTS

Most countries have significant grass and weed pollen seasons during April to May and September to October, respectively. Indigenous trees such as date palm, acacia, and mesquite have specific pollen seasons from March to May. Mold allergens are perennial with seasonal peaks, whereas house dust mite is common in humid coastal regions.

CONCLUSIONS

Seasonal and perennial allergens observed in the United States are also found in the Middle East. Furthermore, the prevalence of allergic rhinitis in these countries suggests that local aeroallergens exacerbate symptoms. Health care providers should counsel deploying soldiers with allergic rhinitis regarding relevant allergen trends, ensuring that these individuals have appropriate medications.
