To study the role of atmospheric pollen on respiratory allergy and asthma-related hospitalization (ARH), a pollen calendar was prepared for a suburban area (Habra) of West Bengal, near India-Bangladesh border on the basis of seven-year (2007-2013) aeropollen monitoring with Burkard slide-sampler. Among 40 pollen types, Poaceae/grass showed highest contribution (12.32%) followed by Trema orientalis (11.45%) and others. Among 30 allergenic pollen types, Poaceae/grass showed the highest sensitivity in skin-prick test (>50%) and IgE-ELISA. ARH of local population (n = 9492) showed significant positive correlation (P < 0.05) with airborne pollen of grass, Bombax ceiba, Mangifera indica and total aeropollen too.
