Severe Acute Respiratory Infections (SARI) Surveillance
Severe acute respiratory infections (SARI) surveillance is currently conducted at selected hospitals in counties along the Mexican border by the Office of Border Health?s Border Infectious Disease Surveillance (BIDS) program. SARI is defined as a hospital admission with a fever of at least 100?F plus either a cough or a sore throat. Enhancing hospital-based surveillance for respiratory pathogens strengthens our ability to detect influenza strains currently in circulation and to monitor various causes of morbidity and mortality among inpatients with SARI. Overall, this will provide a clearer epidemiological picture of influenza activity in our community.
SARI cases are tested by an RT-PCR viral panel test that includes: respiratory syncytial virus A and B; parainfluenza virus 1, 2, 3, and 4; human metapneumoviruses A/B; rhinovirus; adenovirus (ADVB and ADVE); influenza A and B; coronavirus (NL63, HKU1, 229E, and OC43); coxsackieviruses/echovirus; and bocavirus. Serum from these patients is also tested for coccidioidomycosis.
