ABSTRACT

On August 10th 2010 the World Health Organization (WHO) announced the end of the influenza A H1N1 2009 pandemic. On August 13th, three cases of influenza A H1N1 2009 from the local school were confirmed at the Hospital de Chile Chico. An epidemiological investigation was conducted in conjunction with the regional health authority (SEREMI), in order to monitor the outbreak and establish appropriate control strategies. During the study period (august 7 to 21), 304 cases of influenza-like-illness (ILI) were reported, with an incidence of 6171 cases per 100.000 in epidemiological week n° 33. Most of the affected people were 19 years old or younger (68 percent of cases). Hospitalized patients (n: 7) had a favorable outcome, without severe symptoms or need for transfer to an intensive care unit. A female patient with a congenital heart defect who had not been vaccinated was the only fatal case. The outstanding features of this post-pandemic outbreak were its intensity and the demonstration of the importance of control measures to prevent further spread of influenza A H1N1 2009 infections, in the community setting.


El 10 de agosto de 2010 la Organización Mundial de la Salud (OMS) declaró el fin de la pandemia por el virus influenza A H1N1 2009. El 13 de agosto, se confirmaron tres casos de influenza A H1N1 2009 en el Hospital de Chile Chico provenientes de la escuela local. Se inició una investigación epidemiológica en conjunto con la autoridad sanitaria regional (SEREMI) para monitorizar la evolución del brote y para implementar medidas de prevención y mitigación del contagio. Durante el período de estudio (7 al 21 de agosto) se registraron 304 casos de enfermedad tipo influenza (ETI), alcanzando una incidencia durante la semana epidemiológica 33 de 6.171 casos por 100.000 habitantes. Los menores de 19 años fueron el grupo etario más afectado (68 por ciento de los casos). Los pacientes que requirieron hospitalización (n: 7) evolucionaron favorablemente y ninguno requirió traslado a una unidad de cuidado intensivo. Sólo se consignó un caso fatal durante el brote, en una paciente con co-morbilidad cardiaca y sin vacuna. Este brote infeccioso destaca por su intensidad en el contexto del período post-pandémico e ilustra sobre la importancia de las medidas de prevención del contagio por influenza A H1N1 2009 a nivel comunitario.
