J Adolesc Health 2021 69 (1) 144-148 PURPOSE: The purpose of this study was to analyze trends in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) testing and test positivity among persons aged <18 years in a three-site outpatient pediatric practice in Atlanta, Georgia, serving approximately 35,000 pediatric patients. METHODS: Using electronic medical records, weekly trends in SARS-CoV-2 tests performed and the 14-day moving average of test positivity were examined, overall and by age group, during May 24-December 5, 2020. RESULTS: Among 4,995 patients who received at least 1 SARS-CoV-2 test, 6,813 total tests were completed. Overall test positivity was 5.4% and was higher among older pediatric patients (<5 years: 3.3%; 5-11 years: 4.1%; 12-17 years: 8.6%). The number of tests and test positivity increased after holidays and school breaks. CONCLUSIONS: Families might benefit from communication focused on reducing SARS-CoV-2 transmission during holidays. In addition, given higher test positivity in children aged 12-17 years, tailoring public health messaging to older adolescents could help limit SARS-CoV-2 transmission risk in this population. |
Community-based prevention of epidemic Rocky Mountain spotted fever among minority populations in Sonora, Mexico, using a One Health approach

Trans R Soc Trop Med Hyg 2019 114 (4) 293-300 BACKGROUND: Rocky Mountain spotted fever (RMSF) is a significant public health problem in Sonora, Mexico, resulting in thousands of cases and hundreds of deaths. Outbreaks of RMSF are perpetuated by heavy brown dog tick infestations in and around homes. During 2009-2015, there were 61 RMSF cases and 23 deaths in a single community of Sonora (Community A). METHODS: An integrated intervention was carried out from March-November 2016 aimed at reducing tick populations with long-acting acaricidal collars on dogs, environmental acaricides applied to peri-domestic areas and RMSF education. Tick levels were measured by inspection of community dogs to monitor efficacy of the intervention. A similar neighborhood (Community B) was selected for comparison and received standard care (acaricide treatment and education). RESULTS: The prevalence of tick-infested dogs in Community A declined from 32.5% to 8.8% (p<0.01). No new cases of RMSF were identified in this area during the subsequent 18 mo. By comparison, the percentage of tick-infested dogs in Community B decreased from 19% to 13.4% (p=0.36) and two cases were reported, including one death. CONCLUSIONS: Community-based interventions using an integrated approach to control brown dog ticks can diminish the morbidity and mortality attributable to RMSF. |
Rocky Mountain spotted fever and pregnancy: Four cases from Sonora, Mexico
Licona-Enriquez JD , Delgado-de la Mora J , Paddock CD , Ramirez-Rodriguez CA , Candia-Plata MDC , Hernandez GA . Am J Trop Med Hyg 2017 97 (3) 795-798 We present a series of four pregnant women with Rocky Mountain spotted fever (RMSF) that occurred in Sonora, Mexico, during 2015-2016. Confirmatory diagnoses were made by polymerase chain reaction or serological reactivity to antigens of Rickettsia rickettsii by using an indirect immunofluorescence antibody assay. Each patient presented with fever and petechial rash and was treated successfully with doxycycline. Each of the women and one full-term infant delivered at 36 weeks gestation survived the infection. Three of the patients in their first trimester of pregnancy suffered spontaneous abortions. RMSF should be suspected in any pregnant woman presenting with fever, malaise and rash in regions where R. rickettsii is endemic. |
