In order to understand the clinical and epidemiological aspects of infection with the AH1N1 influenza virus in Chile, a prospective study in the city of San Felipe was undertaken. It analyses the trends in consultations for respiratory causes in three primary care centers and hospital discharges by comparing data from years 2008 and 2009 until epidemiological week 37.It also includes a study of cases of ILI / SARI (influenza like disease/severe acute respiratory disease) in which viruses were detected by direct immunofluorescence (DIF) of nasopharyngeal aspirates and by real-time polymerase chain reaction in the case of influenza A (H1N1) 2009. A household survey was conducted in those cases with confirmed A (H1N1) infection, to identify contacts and history related to influenza virus transmission. The results indicate that the behavior of the pandemic was similar to that observed in the rest of the country, with an increase in emergency room visits for ILI. The most affected age group was from 5 to 14 years (26.5 per thousand inhabitants) and the least affected 60 years or older (1.2 per thousand). A 2.78% of the cases corresponded to SARI and the fatality rate was 0.11%.

In Chile Vibrio parahaemolyticus has been detected in 3 gastroenteritis outbreaks since 1998. The most recent outbreak occurred during the summer of 2005, affecting over 10,000 people of whom one died. Affected individuals presented with one or more of the following symptoms: diarrhea, nausea, vomiting, abdominal pain and/or fever. Fecal white blood cells were detected in only 6% of patients. The predominant serotype in the 3 outbreaks was the pandemic O3:K6 strain. Diagnosis was confirmed by isolation and identification of V. parahaemolyticus in stool cultures and/or by establishing an epidemiological link. V. parahaemolyticus isolates were 100% susceptible to tetracycline, ciprofloxacin and chloramphenicol, and universally resistant to ampicillin. Due to the public health impact of the 2005 outbreak, the Ministry of Health called for a National Task Force mandated to review epidemiological, clinical and microbiological features of the outbreak and to propose management guidelines.
Situación epidemiológica actual de la triquinosis en Chile. 1991-2000

The incidence and prevalence of trichinosis shows a constant decline in Chile. Considering the geographical characteristics of Chile, it is possible that an undetermined number of pigs are home reared and butchered without veterinary control, constituting an important source of human trichinosis.
