Influenza Report
Epidemiological Week 35 (August 29 to September 4, 2010)
extracts....
Thus, in Chile there has been an increase in consultations breathing during the last five weeks. RSV circulation has declined in recent weeks (36% of total virus), followed by influenza B virus and parainfluenza. Continued co-circulation of influenza A H1N1 and H3N2, the latter, tripling to pandemic influenza.
1 .- Trends and intensity of the activity of respiratory disease: Influenza Type Disease (ETI) in sentinel clinics.
In epidemiological week 35, the TSI activity, as measured by sentinel surveillance, is intensity elevada1. Highlights the increasing trend reaching a rate of 61 per 100,000, up 60% respect to the previous week (39 per100,000), remaining one third week on the area Channel alert endemic. Last winter (2009) the highest rates were recorded between weeks 25 and 27 (July) and in previous years from May to June, so this year's increase is seasonal displaced. It is noteworthy that in 2002, there was a seasonal outbreak of influenza late, with a maximum in week 33, which circulated primarily Influenza A (H1) and influenza B 2.
Regionally, Los Ríos and Los Lagos have the highest rates, reaching very high intensity. In RM, Bío Bío, Araucanía, Los Ríos, Los Lagos and Aysen recorded a significant increase in the notification during week 35, with respect to the previous week. Only in Atacama is not recorded activity in the sentinel ambulance. Influenza cases were detected in Arica, Iquique, Valparaiso, Linares, Concepcion, Valdivia, Puerto Montt and Santiago.
In addition, there are occurrences of Influenza B in Viña del Mar Santiago and Valdivia Linares (figures in annex 1).

2 .- Monitoring respiratory causes Hospitality in Hospital Emergency Services
According to information provided by the Department of Health Statistics and Information, MINSAL andanalyzed in conjunction with the Undersecretary of Assistance Networks, the percentage of visits for causesrespiratory emergency services presents a further increase from 32 SE (second week of
August), associated mainly to the increase in visits for upper IRA and influenza. At week 353 is this trend to increase, representing 42% of the consultations, three points higher in relation to the previous week (39%) and those observed in 2009. This increase is most marked in children, accounting for 59.5% of all searches, while in adults is 28.5%.

Annex 2 shows trend graphs of those emergency departments that make up since years of monitoring network for health services for respiratorias4. Maintaining the increased attention ARI in children in Viña, Concepción, Temuco and Puerto Montt. The adult care also increases being more intense in Concepción and Puerto Montt. In Santiago declined in children and adults.
3 .- Grave confirmed cases of ARF
239 were confirmed cases of H1N1 influenza severe ARI (2009) in the country (1.4 per hundred thousand inhabitants). The highest rate occurs in the region of Los Rios (21.3 per hundred thousand inhabitants), followed by the Region of the Lagos. Women concentrate the highest rate with 1.5 per hundred thousand inhabitants (126 cases). There is an increase in the number of cases since week 31, concentrated mainly in the Region Metropolitana. In the regions of Tarapaca and Magallanes no confirmed cases of serious Ira H1N1 virus (2009).

5 .- viral Circulation
At week 35, were processed in the network of surveillance of respiratory viruses, 20 890 samples, of which 6543 (31.3%) were positive for viruses. Of these 6543 positive samples, 8% have been influenza pandemic A (H1N1), which corresponds to 525 samples.
The year 2009 was processed in the surveillance network a total of 51 408 samples, of whom 34% had an outcome positive for respiratory viruses such positive, 23% were influenza pandemic. RSV circulation has been declining in the last week (36% of virus at week 35). The influenza B accounts for 14% of viruses identified the SE 35, surpassing the parainfluenza virus. Regarding the influenza A, continues the co-circulation of influenza A H1N1 and H3N2, the latter tripling influenza cases pandemic.
