The VA established a presumptive service connection for asthma, rhinitis, and sinusitis to exposures to burn pits during service for all service members who served in the Southwest Asia theater of operations since 1990. In addition, those who served in Afghanistan, Djibouti, Syria, and Uzbekistan since Sept. 19, 2001, are also eligible for this connection. Veterans must have been ill within ten years of their active service.
