H1N1 pandemic influenza impact on hand hygiene and specific precautions compliance among healthcare workers

Adherence to hand hygiene at five moments and specific protection in a tertiary care hospital during the COVID-19 pandemic

“…15 In 2011, after the 2009 H1N1 influenza epidemic, a multimodal hand hygiene study was carried out at the Children's Hospital, National Medical Center Siglo XXI of the Mexican Institute of Social Security: the prevalence of hand washing was 51 %, and 38.9 % did it at all five recommended moments (p < 0.05). 16 Adherence to hand washing in this study was higher than in previous reports at the same institution, which is a finding similar to that reported by Labarca et al, 7 who found higher adherence during the H1N1 influenza pandemic, in comparison with a previous period and a period after it. Although no cause was found for this effect, it can be attributed to the intense educational campaigns regarding prevention and the fear of contagion.…”

The assigned protection factor of these respirators is 10 (30) , but lower performance was considered due to issues with long-term fit and use practices.…”

Apego a higiene de manos en 5 momentos y protección específica en un hospital de tercer nivel ante la pandemia de COVID-19

“…15 En 2011, después de la epidemia de influenza H1N1 en 2009, se llevó a cabo un estudio multimodal de higiene de manos en el Hospital de Pediatría, Centro Médico Nacional Siglo XXI del Instituto Mexicano del Seguro Social: la prevalencia del lavado de manos fue de 51 % y 38.9 % lo hizo en los cinco momentos recomendados (p < 0.05). 16 El apego al lavado de manos en este estudio fue superior al de reportes previos en esa misma institución, hallazgo similar al encontrado por Labarca et al, 7 quienes encontraron un apego mayor durante la pandemia por influenza H1N1, en comparación a un periodo anterior y posterior a esta. Aunque no se encontró una causa de este efecto, se puede atribuir a las intensas campañas de educación en cuanto a prevención y al temor de contagiarse.…”
