Background. After decades of obscurity, Zika virus (ZIKV) has spread through the Americas since 2015 accompanied by congenital microcephaly and Guillain-Barré syndrome. Although these epidemics presumably involve transmission Aedes aegypti, no direct evidence vector involvement been reported, prompting speculation that other mosquitoes such as Culex quinquefasciatus could be involved. Methods. We detected an outbreak ZIKV infection in southern Mexico late 2015. Sera from suspected...
Since chikungunya virus (CHIKV) was introduced into the Americas in 2013, its geographic distribution has rapidly expanded. Of 119 serum samples collected 2014 from febrile patients southern Mexico, 79% were positive for CHIKV or IgM against CHIKV. Sequencing results confirmed strains closely related to Caribbean isolates.
During a chikungunya fever outbreak in late 2014 Chiapas, Mexico, entomovirological surveillance was performed to incriminate the vector(s). In neighborhoods, 75 households with suspected cases were sampled for mosquitoes, of which 80% (60) harbored Aedes aegypti and 2.7% (2) albopictus . A total 1,170 Ae. three collected 81 pools generated. Although none virus (CHIKV)–positive, 18 (22.8%) contained CHIKV, yielding an infection rate 32.3/1,000 mosquitoes. lack herd immunity conjunction high...
Aedes aegypti control programs require more sensitive tools in order to survey domestic and peridomestic larval habitats for dengue other arbovirus prevention areas. As a consequence of the COVID-19 pandemic, field technicians have faced new occupational hazard during their work activities surveillance control. Safer strategies monitor populations, addition minimum householder contact, are undoubtedly urgently needed. Drones can be part solution urban rural areas that dengue-endemic....
The studie describes the blood-feeding behaviour of mosquitoes in Mexico, to understand host-vector relationships and dynamics disease transmission.From September 2012 November 2013, 911 blood-fed Cx. quinquefasciatus were collected with aspirators inside houses Chetumal Cancun. Blood meals analysed by PCR subsequent Sanger sequencing cytochrome b gene.93.3% fed on mammals, 6.5% birds 0.2% reptiles. most frequent vertebrate hosts humans (65.4%), dogs (23.2%), chicken (5.4%), cattle (2.2%)...
The emerging chikungunya virus (CHIKV), is an arbovirus causing intense outbreaks in North America. situation Mexico alarming, and CHIKV threatens to spread further throughout Clinical biological features of CHIKF have not been well described; thus, we conducted a cross sectional study outbreak Chiapas, Southern characterize these features.We collected blood samples from patients suspected having fever (CHIKF) who presented Hospital ISSSTE Dr. Roberto Nettel Tapachula, Mexico. In addition...
<h2>Abstract</h2><h3>Background</h3> Genetic risk factors for dengue hemorrhagic fever/dengue shock syndrome (DHF/DSS) and fever (DF) are limited, in particular there sparse data on genetic across diverse populations. <h3>Methods</h3> We conducted a genome-wide association study (GWAS) derivation validation sample of 7, 460 participants Latin American, South Asian, East Asian ancestries. then developed weighted polygenic score (PRS) each participant the cohorts three ancestries to predict...
Abstract Background Aedes aegypti and albopictus are the main mosquito species responsible for dengue virus ( DENV ) transmission to humans in tropical subtropical regions of world. The role vertical epidemiology maintenance this arbovirus nature during interepidemic periods remain poorly understood, could sustain existence reservoirs within populations. Methods Between April 2011 October 2012, we monitored Ae. 9 cities 4 Mexican states. eggs were collected ovitraps, then adults reared under...
Zika virus (ZIKV) is an arthropod-borne (arbovirus) of the genus Flavivirus within family Flaviviridae, originally isolated from blood a febrile rhesus macaque in Ziika forest ...
In October 2011, the State Health Department announced that several laboratory-confirmed cases of dengue had occurred among residents in two neighborhoods Benito Juarez, Quintana Roo State, Mexico. To identify virus serotype(s) temporally and spatially associated with cases, entomologic-based surveillance was initiated 2011 both neighborhoods. Adult mosquitoes were collected from 88 houses by CDC-backpack aspirator, all female Aedes aegypti L. (n = 419) individually homogenized assayed pools...
Evidence of vertical transmission dengue virus (DENV) in yellow fever mosquito, Aedes aegypti (L.), was found at Cancun, Quintana Roo, Mexico. Ae. larvae were collected from 729 containers a total 178 households between September and November 2012. Larvae put into sterile bags transported thermoses. RT-PCR followed by semi-nested PCR for molecular serotyping used to evaluate larval pools. Of the houses sampled, 79 (44.4%) positive last one larva. The breeding sites grouped Only three pools...
SUMMARY The prevalence of pediculosis in Mexican children was studied San Nicolas and Tapachula, Mexico. A cross-sectional study included 888 students between six 12 years old from two urban communities with an unequal socioeconomic status September 2015 March 2016. Pearson χ2 multivariate logistic analysis were carried out to associate risk factors pediculosis. overall both localities 23.9%. female gender; long medium hair; living someone infested; previously infested by head lice curling...
Sensitivity of monitoring Aedes aegypti (L.) populations was determined to identify the distribution dengue virus (DENV) during epidemics in Quintana Roo. From September November 2012, we used a motorized aspirator collect 2,144 female Ae. from 569 homes. These were grouped into 220 use semi-nested RT-PCR for DENV, and positive groups analyzed individually. Five (2.27%) DENV. Individual analysis yielded eight that tested positive, six with DENV-2, one DENV-1, DENV-4. The latter not reported...
The 25th Annual Latin American Symposium presented by the Mosquito Control Association (AMCA) was held as part of 81st Meeting in New Orleans, LA, March 2015. principal objective, for previous 24 symposia, to promote participation AMCA vector control specialists, public health workers, and academicians from America. This publication includes summaries presentations that were given orally Spanish participants Colombia, Mexico, USA. Topics addressed symposium included: surveillance,...
Dengue and other Aedes-borne diseases have dramatically increased over the last decades. The Sterile Insect Technique (SIT) has been successfully used as part of integrated pest strategies to control populations insect-plant livestock pests is currently being tested a potential method reduce mosquito in an environmentally friendly approach. However, during mass rearing steps needed produce millions mosquitoes, egg storage preservation are essential for certain amount time. Eggs...
