We describe the evolution and features of a cluster of Multidrug-resistant tuberculosis (MDR TB) cases that occurred in 2001, in a school located in a sub-urban area of the district of Ica, Peru. We identified 15 students related before becoming infected with tuberculosis. The mean age of the cluster was 15 years. A total of 12 students were MDR-TB cases and 7 were drug-resistant to 5 first-line drugs (RHEZS). Five out of the 15 cases received at least 3 different anti-tuberculosis treatment schemes. The average treatment duration was 37 months (minimum 21 and maximum 59 months). A total of 13 cases recovered and 2 died. This study describes a cluster of MDR -TB cases in an educational facility, which due to the epidemiological link and time presentation, is probably an outbreak of MDR TB with a satisfactory outcome after prolonged treatment.

The aim of this research was to determine the impact of the strategy of multi-micronutrient supplementation (MMN) on the childhood anemia in three Andean regions of Peru. A sentinel surveillance system was established in 29 health centers of Andahuaylas, Ayacucho and Huancavelica (Peru) to monitor a cohort of children of 6 to 35 months of age whom been received MMM for a period of 12 months. Data regarding hemoglobin levels were gathered at the beginning and at the end of the research; they included consumption of MMN, and other data from clinical records and from growth and development charts. Between the child who completed the supplementation, the prevalence of anemia decreased from 70.2% to 36.6% (p value <0.01). 55,0% and 69,1% of children with mild and moderate anemia at the beginning of the supplementation got cured. This research shows that supplementation with MMN could be a valuable strategy to fight anemia.

Objetives. To establish the existence of concurrent infections by different dengue virus (DENV) serotypes in an outbreak in the Northwestern in Peru during 2008. Material and methods. 73 serum samples from patients with dengue were analyzed during an outbreak that occurred in Northwestern in Peru between May and June 2008. Molecular biology techniques were used to serotype the DENV, thus, firstly the viral RNA viral was extracted using Viral QIAamp RNA mini kit (Qiagen, Valencia, California, USA), then the viral cDNA fragments were reverse transcripted and amplified by means of the Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) and the RT-Nested PCR region techniques and finally, genetic sequencing of the viral cDNA fragments were performed using the Big Dye Terminator v.3,1 kit. Results. The 73 dengue cases presented infections by different serotypes: 34 (46.6%) by DENV-3, 29 (39.7%) by DENV-1, 4 (5.5%) by DENV-4, and 6 (8.2%) concurrent infections by DENV-1 and DENV-3. The most frequent clinical manifestations observed among dengue patients were fever and headache (100%), myalgia (94.5%), ocular pain (83.6%), arthralgia (78.1%), shivers (63.0%), nausea/vomiting (38.4%), positive tourniquet test (30.1%), and rash (20.5%). All patients with concurrent infections presented light clinical course of dengue fever (Df) except one patient who had moderate hemorrhagic manifestations. Conclusion. This is the first Peruvian report of patients with concurrent infections of two DENV serotypes without severe clinical manifestations.


Objective. Design and implement a surveillance method for locating Aedes aegypti infestation foci with the use of larvae traps and spatial interpolation techniques, which facilitate the ongoing estimation of vector abundance in the area by counting the individuals collected in the study area. Methods. A total of 228 larvae traps were installed-at a rate of one per block-in the most densely populated area of commune five of Villavicencio (Meta). With regionalized information on larvae abundance, spatial interpolations were conducted with the Voronoi polygon, ordinary kriging, and inverse distance weighting techniques. Results. An alternative method for the surveillance of dengue vectors is presented. This method is based on the use of larvae traps and spatial interpolation techniques to obtain area maps supported by specific observations. Conclusions. The results show that this strategy is better than the indices normally used, since it facilitates continuous visualization of the level of vector infestation and consequently, the risk of dengue transmission, based on the extent of A. aegypti infestation. Implementation of this strategy is expected to contribute to more effective planning, optimization, and evaluation of prevention and control activities.

Characterizing breastfeeding in Puerto Carreo and identifying factors associated with providing breast-milk for the newborn, exclusive breastfeeding and total breastfeeding.This descriptive, cross-sectional study, using structured individual and non-random surveys, involved 609 mothers. The statistical analysis methods included univariate and bivariate analysis, survival curves, binary logistic regression and Cox proportional hazard models.The duration of total and exclusive breastfeeding was higher than reported times at national and regional level in most cases. The main factors associated with breastfeeding were related to occupation, family background, Indigenous status, previous maternal experience and access to healthcare services.Exclusive breastfeeding was influenced more by the mothers occupation, while the total duration of breastfeeding was influenced by home-based family support network. The results are significant regarding planning intervention measures addressed towards improving breastfeeding habits in the target municipality.
