This report describes how national COVID-19 vaccination coverage was lower in counties with some of the most socially vulnerable communities and higher least communities.
Abstract Most models exploring the effects of climate change on mosquito‐borne disease ignore thermal adaptation. However, if local adaptation leads to changes in mosquito responses, “one size fits all” could fail capture current variation between populations and future adaptive responses temperature. Here, we assess phenotypic temperature Aedes aegypti , primary vector dengue, Zika, chikungunya viruses. First, explore whether there is any difference existing response mosquitoes populations,...
During July 7-11, 2023, CDC received reports of two patients in different states with a tuberculosis (TB) diagnosis following spinal surgical procedures that used bone allografts containing live cells from the same deceased donor. An outbreak associated similar product manufactured by tissue establishment (i.e., manufacturer) occurred 2021. Because concern these cases represented second outbreak, and Food Drug Administration worked to determine this was obtained donor one implicated 2021...
Abstract Background Carbapenemase-producing, carbapenem-resistant Pseudomonas aeruginosa (CP-CRPA) are extensively drug-resistant bacteria. We investigated the source of a multistate CP-CRPA outbreak. Methods Cases were defined as US patient's first isolation P. sequence type 1203 with carbapenemase gene blaVIM-80 and cephalosporinase blaGES-9 from any specimen collected reported to Centers for Disease Control Prevention during 1 January 2022–15 May 2023. conducted 1:1 matched case-control...
The effects of animal agriculture on the spread antibiotic resistance (AR) are cross-cutting and thus require a multidisciplinary perspective. Here we use ecological, epidemiological, ethnographic methods to examine populations Escherichia coli circulating in production poultry farming environment versus domestic rural Ecuador, where small-scale employing nontherapeutic antibiotics is increasingly common. We sampled 262 "production birds" (commercially raised broiler chickens laying hens)...
Early COVID-19 mitigation relied on people staying home except for essential trips. The ability to stay may differ by sociodemographic factors. We analyzed how factors related social vulnerability impact a community's during stay-at-home order.Using generalized, linear mixed models stratified order (mandatory or not mandatory), we county-level behavior (inferred from mobile devices) period when majority of United States counties had orders (April 7-April 20, 2020) with the Centers Disease...
Insecticide resistance has evolved in disease vectors worldwide, creating the urgent need to either develop new control methods or restore insecticide susceptibility regain use of existing tools. Here we show that phenotypic can be restored a highly resistant field-derived strain Aedes aegypti only 10 generations through rearing them absence insecticide.
Abstract Background Group B Streptococcus (GBS) is a major cause of neonatal sepsis. Outbreaks GBS late-onset disease (LOD), defined as infection during the first 7–89 days life, are uncommon. In September 2023, 4 LOD cases were reported by intensive care unit (NICU) to Connecticut Department Public Health (DPH). We investigated characterize outbreak and guide response. Methods identified patients with invasive (i.e., isolated from sterile site) hospitalized in NICU through review data DPH’s...
Abstract Background Plasmid-mediated outbreaks have been associated with gaps in infection control (IC) and environmental reservoirs such as sink drains. In October 2023, the Virginia Department of Health (VDH) identified a cluster four Klebsiella pneumoniae carbapenemase (KPC)-producing variicola urinary tract infections among patients at Acute Care Hospital A (ACH A). VDH CDC collaborated to investigate source prevent further transmission. Methods We reviewed medical records, directly...
There is concern that increases in temperature due to climate change could lead shifts the dynamics and distribution of mosquito vectors. Many current models assume there are average thermal performance curves for a given vector species transmission. However, this one-size-fits-all assumption ignores potential local adaptation create population-specific differences performance. In study, we explored five independent field populations Ae. aegypti from Mexico, together with standard laboratory...
As resistance to insecticides increases in disease vectors, it has become exceedingly important monitor populations for susceptibility. Most studies of field Aedes aegypti have largely characterized patterns at the spatial scale city or country, which may not be completely informative given that insecticide application occurs house block. Phenotypic pyrethroids dominates Ae. aegypti, and been partially explained by mutations voltage-gated sodium channel gene. Here, we assess community-level...

The recognition that irrigation water sources contribute to preharvest contamination of produce has led new regulations on testing microbial quality. To best identify problems, growers who depend ponds need guidance how and where collect samples for testing. In this study, we evaluated several sampling strategies Salmonella Escherichia coli in five used farms southern Georgia. Both E. were detected regularly all the over 19-month study period, with overall prevalence concentrations...
There is substantial concern that the spread of insecticide resistance will render long-lasting insecticide-treated nets (LLINs) ineffective. However, there limited evidence supporting a clear association between and malaria incidence or prevalence in field. We suggest one reason for this disconnect standard WHO assays used surveillance to classify mosquito populations as resistant are not designed determine how might impact LLIN efficacy. The expose young, unfed female mosquitoes diagnostic...
Understanding mechanisms driving insecticide resistance in vector populations remains a public health priority. To date, most research has focused on the genetic underpinning resistance, yet it is unclear what role environmental drivers may play shaping phenotypic expression. One of key Aedes aegypti mosquito population dynamics resource-driven intraspecific competition at larval stage. We experimentally investigated density-dependent mediating evolution Ae. aegypti, using knockdown (kdr) as...
Abstract Insecticide-treated bed nets reduce malaria transmission by limiting contact between mosquito vectors and human hosts when mosquitoes feed during the night. However, can also in early evening morning people are not protected. Here, we explored how timing of blood feeding interacts with environmental temperature to influence capacity Anopheles transmit parasite, Plasmodium falciparum . We found no effect biting time itself on proportion that became infectious (vector competence) at...
Mycobacterium abscessus is an intrinsically drug-resistant, rapidly growing, nontuberculous mycobacterium; extrapulmonary infections have been reported in association with medical tourism (1).During November-December 2022, two Colorado hospitals (hospitals A and B) treated patient A, a woman aged 30-39 years, for M. meningitis.In October she had received intrathecal donor embryonic stem cell injections Baja California, Mexico to treat multiple sclerosis subsequently experienced headaches...
Background: The first Zika virus outbreak in U.S. Virgin Islands identified 1031 confirmed noncongenital disease (n = 967) and infection 64) cases during January 2016-January 2018; most (89%) occurred July-December 2016. Methods Results: epidemic followed a continued point-source pattern. Evaluation of sociodemographic risk factors revealed that estates with higher unemployment, more houses connected to the public water system, newly built were significantly less likely have cases. Increased...
