Brote de brucelosis interprovincial por ingesta de queso fresco sin higienizar

Goal: To study an August 2004 outbreak of brucellosis notified in Velez-Rubio (Almeria) and to determine the source of that infection as well as its transmission mechanisms, in addition to proposing preventive measures. Methodology: Descriptive study and paired case controls (three controls were selected for each case). Setting: Health Centers in de Vélez-Rubio (Almeria) and Alcalá de Guadaira (Seville). Population: Suspected/probable case: a person with compatible clinical symptoms and positive brusella agglutination diagnosed between July 2005 and March 2005. Confirmed case: in addition to identifying the causal agent, laboratory test results resulted in a confirmation. Interventions: Report forms, epidemiological surveys, clinical histories, and laboratory tests were used as sources of data. Odds ratios (OR) and confidence intervals were calculated to study the relationship among cases, sources of infection, and transmission mechanisms. The Chi Square test and Yates correction were employed. Results: 10 cases were identified (9 in Almeria and 1 in Seville), 8 of them pobable and 2 confirmed, in persons between the ages of 45 and 81. The symptoms first appeared between the months of May and September 2005. Fever was the most frequent symptom (100%). The OR for the consumption of fresh, non.-pasteurized cheese was 112 (CI 4,48-16968,94), p< 0,001. Infected animals were intervened. Conclusions: The inter-provincial outbreak of brucellosis was confirmed as stemming from the consumption of non-pasteurized cheese sold on the street. The source of infection was identified and the Department of Agriculture carried out the necessary actions.

Infección por virus pandémico (H1N1) 2009 en Andalucía

In April 2009, in response to the WHO's alert due to the existence of human infection cases with a new AH1N1 influenza virus, known as swine flu, Andalusian Health Authorities trigger an specific action plan. The surveillance actions developped provided us with appropriate clinical, epidemiological and virological characteristics of the disease. During the first few days, contingency plans were set up based on epidemiological surveillance and outbreak control measures were adopted through early alert and rapid response systems. After phase 6 was declared, influenza sentinel and severe cases surveillance were used in order to plan healthcare services, to reduce transmission and to identify and protect the most vulnerable population groups. Behaviour of pandemic influenza in Andalusia was similar to that observed in the rest of the world. Atack rate was similar to a seasonal flu and the peak was reached at the 46th/2009 week. Most of them were mild cases and affected particularly to young people. The average age of hospitalised patients was 32. Prior pulmonary disease, smoking and morbid obesity (BMI>40) were the most common pathologies and risk factors in severe cases. An impact scenario of pandemic wave in Andalusia, with an expected attack rate from 2 to 5%, was prepared considering watt observed in the southern hemisphere. Characteristics of the epidemic concerning its extent, severity and mortality rate were adjusted to this scenario.
