PLOS Glob Public Health 2023 3 (9) e0002326 Voluntary medical male circumcision (VMMC) has primarily been promoted for HIV prevention. Evidence also supports that male circumcision offers protection against other sexually transmitted infections. This analysis assessed the effect of circumcision on syphilis, hepatitis B virus (HBV) infection and HIV. Data from the 2015 to 2019 Population-based HIV Impact Assessments (PHIAs) surveys from Rwanda, Tanzania, Uganda, Zambia, and Zimbabwe were used for the analysis. The PHIA surveys are cross-sectional, nationally representative household surveys that include biomarking testing for HIV, syphilis and HBV infection. This is a secondary data analysis using publicly available PHIA data. Univariate and multivariable logistic regression models were created using pooled PHIA data across the five countries to assess the effect of male circumcision on HIV, active and ever syphilis, and HBV infection among sexually active males aged 15-59 years. Circumcised men had lower odds of syphilis infection, ever or active infection, and HIV, compared to uncircumcised men, after adjusting for covariates (active syphilis infection = 0.67 adjusted odds ratio (aOR), 95% confidence interval (CI), 0.52-0.87, ever having had a syphilis infection = 0.85 aOR, 95% CI, 0.73-0.98, and HIV = 0.53 aOR, 95% CI, 0.47-0.61). No difference between circumcised and uncircumcised men was identified for HBV infection (P = 0.75). Circumcised men have a reduced likelihood for syphilis and HIV compared to uncircumcised men. However, we found no statistically significant difference between circumcised and uncircumcised men for HBV infection. |
Rocky Mountain Spotted Fever in a Large Metropolitan Center, Mexico-United States Border, 2009-2019
Zazueta OE , Armstrong PA , Márquez-Elguea A , Hernández Milán NS , Peterson AE , Ovalle-Marroquín DF , Fierro M , Arroyo-Machado R , Rodriguez-Lomeli M , Trejo-Dozal G , Paddock CD . Emerg Infect Dis 2021 27 (6) 1567-76 Epidemic levels of Rocky Mountain spotted fe---ver (RMSF) have persisted in Mexicali, Mexico, since the initial outbreak was first reported in December 2008. We compared clinical and epidemiologic data of cases in Mexicali during 2009-2019 between patients with an IgG titer reactive with Rickettsia rickettsii bacteria by indirect immunofluorescence antibody (IFA) assay and those who demonstrated DNA of R. rickettsii in a whole blood sample when tested by PCR. We identified 4,290 patients with clinical and epidemiologic features compatible with RMSF; of these, 9.74% tested positive by IFA and 8.41% by PCR. Overall, 140 patients died (11-year case-fatality rate 17.97%). Substantial differences in the frequency of commonly recognized clinical characteristics of RMSF were identified between PCR-positive and IFA-positive cases. The Mexicali epidemic is unique in its size and urban centralization. Cases confirmed by PCR most accurately reflect the clinical profile of RMSF. | Longevity, high prevalence, and multifocal distribution of this disease pose unprecedented public health challenges. | eng |
National surveillance data show increase in spotted fever rickettsiosis: United States, 2016-2017
Heitman KN , Drexler NA , Cherry-Brown D , Peterson AE , Armstrong PA , Kersh GJ . Am J Public Health 2019 109 (5) 719-721 From 2016 through 2017, unprecedented increases in all nationally notifiable tickborne diseases were reported to the Centers for Disease Control and Prevention (CDC). The largest percentage increase was seen in reported cases of spotted fever rickettsiosis (SFR): a 46% increase from 4269 cases to a record 6248.1 Increases were reported in both new areas and in known endemic states. Although the New England, East North Central, and Middle Atlantic regions typically report only a handful of cases each year, in 2017, these areas experienced, a 215%, 78%, and 65% increase in reported cases, respectively. Among tickborne diseases, only anaplasmosis, with a 39% increase during this time, approached the rise seen with SFR. Although this increase raises concerns for elevated disease risk, additional factors are likely contributing to the high number of reports. |
Clonally related Burkholderia contaminans among ventilated patients without cystic fibrosis
Peterson AE , Chitnis AS , Xiang N , Scaletta JM , Geist R , Schwartz J , Dement J , Lawlor E , Lipuma JJ , O'Connell H , Noble-Wang J , Kallen AJ , Hunt DC . Am J Infect Control 2013 41 (12) 1298-300 We investigated a cluster of 10 Burkholderia cepacia complex-positive cultures among ventilated patients and those with a tracheostomy in an acute care hospital. Isolates from 5 patients had outbreak-strain-related Burkholderia contaminans. Isolates of B. cepacia complex unrelated to the outbreak strain were cultured from a sink drain. The investigation identified practices that might have led to contamination of patient respiratory care supplies with tap water, which might have contributed to the cluster. |
Correlation between animal nasal carriage and environmental methicillin-resistant Staphylococcus aureus isolates at U.S. horse and cattle farms
Peterson AE , Davis MF , Awantang G , Limbago B , Fosheim GE , Silbergeld EK . Vet Microbiol 2012 160 539-43 Animals on farms may be a potential reservoir and environmental source of methicillin-resistant Staphylococcus aureus (MRSA). Expanded surveillance methods for animal-associated MRSA are needed. To develop an environmental sampling method and to determine the correlation between animal and environmental MRSA positivity in the farm setting, we sampled horses, cattle, and their local environments at several farms in the mid-Atlantic United States. We obtained nasal swabs from 13 racehorses at first visit, and 11 racehorses at the same farm eight weeks later. We also sampled 26 pleasure horses and 26 beef cattle from two additional farm sites. Sterilized electrostatic cloths were used to collect dry dust samples from environmental surfaces in proximity to animals; cloths were cultured using a broth enrichment protocol. We described isolates by genotype and antimicrobial susceptibility phenotype. None of the samples (nasal or environmental) were positive from the pleasure horse farm or the cattle farm. On the racehorse farm, 8/13 (61%) nasal and 5/7 (71%) environmental samples were positive for MRSA at the first visit. Isolates found were indistinguishable by pulsed-field gel electrophoresis (PFGE) genotype. We observed significant positive correlation between nasal carriage of MRSA in animals and our ability to isolate MRSA from dry surface samples of their local environments. The methods presented here may aid in surveillance efforts for equine and other animal MRSA. This study successfully applies existing MRSA surveillance methods for indoor, high animal density settings to outdoor and low-density farms. |
