Childhood nosocomial viral acute respiratory tract infections in teaching hospital Anuradhapura, Sri Lanka.

OBJECTIVES: We have assessed the risk factors for the occurrence of hospital-acquired (HA) and community-acquired (CA) viral acute respiratory tract infections (ARTIs) in children. Children (1-60 months) who were having ARTI on admission (CA) and develops ARTI following 48 h after admission or 3 days of discharge (HA) were included. Indirect immunofluorescence assay (IFA) was performed and multivariable analyses were done to determine the risk factors for the development of viral CA and HA-ARTI.

RESULTS: Total of 818 with ARTIs, 226 (27.6%) RSV cases were detected. Out of 226, 86 (38.0%) HA-RSV cases were detected. CA-viral-ARTI was significantly high (p < 0.05). Compared to CA-RSV-ARTI immunodeficiency, seizures, trisomy-21 and congenital heart disease (CHD) were having 2.3, 3.2, 1.8- and 2.2-times risk for acquiring HA-RSV respectively. The number of deaths was significantly high following HA-RSV. The associated burden was significant following HA-RSV and it was 429.77 disability-adjusted life years. Children who are having immunodeficiency, CHD, seizure episodes and trisomy 21 would lead to the acquisition of nosocomial RSV infections in great. Adherence to meticulous infection control practices will be helpful to minimize the HA-viral ARTIs in great.
