Water, sanitation, and handwashing interventions that use intensive interpersonal communication improve targeted behaviors, but are expensive at scale. Mass media is an alternative that could reach more people at lower cost but has rarely been rigorously evaluated. We assessed the effectiveness of a mass media campaign in improving handwashing knowledge and practices in rural Bangladesh. Binimetinib MEK inhibitor We conducted a cross-sectional assessment before the campaign among 8,947 households and again after 4 months of the campaign among 8,400 different households in the same areas. Trained enumerators conducted spot checks of water, sanitation, and hygiene facilities, and recorded reported knowledge and practices. We compared these outcomes after versus before the campaign using generalized linear models with robust standard errors. After the media campaign, caregivers were more likely to recall ≥ 3 messages regarding handwashing (prevalence ratio [PR] = 1.44, 1.34-1.55), sanitation (PR = 1.45, 1.35-1.55), and safe water (PR = 1.17, 1.08-1.26). After the campaign, the prevalence of using soap and water during handwashing demonstrations was higher among caregivers (PR = 1.15, 1.12-1.19) and children (PR = 1.31, 1.22-1.41). Hands were more commonly observed to be visibly clean among caregivers (PR = 1.14, 1.07-1.20) and children (PR = 1.13, 1.05-1.21). Soap and water was more commonly observed in handwashing stations near latrines (PR = 1.12, 1.06-1.19) and in cooking/eating places (PR = 1.09, 1.01-1.18). Our findings indicate improved handwashing knowledge and behaviors following a mass media campaign. This promising approach can be deployed to improve water, sanitation, and hygiene practices at scale and should be evaluated in other contexts.Delivery of interventions through group sessions allows for in-depth discussions and creates opportunities for group members to work together to identify and solve common problems. However, low attendance may limit impact. We explored factors affecting attendance, active participation, and behavior change in an integrated group-based child development and maternal and child health intervention in Bangladesh. Community health workers (CHWs) facilitated two sessions a month including material on child stimulation; water, sanitation, and hygiene; nutrition, maternal depression, and lead exposure prevention. Sessions were conducted with 320 pregnant women and mothers with children younger than 24 months, in 16 villages in Kishoreganj district. After 4 and 9 months of intervention, we conducted focus group discussions and in-depth interviews with mothers (n = 55 and n = 48) to identify determinants of attendance and behavior change, and to examine potential for intervention scale-up. Recruiting family members to assist with childcare resulted in improved attention during sessions. Adopting a storytelling format for presentation of session materials resulted in more engaged participation during courtyard sessions. Session attendance and behavior change, especially purchasing decisions, were difficult for participants without the support of male heads of the household. Selecting a rotating leader from among the group members to remind group members to attend sessions and support CHWs in organizing the sessions was not successful. Facilitating self-appraisals and planning for water and sanitation allowed participants to identify areas for improvement and track their progress. Key determinants of a participant's attendance were identified, and the resulting intervention shows promise for future implementation at scale.Leptospirosis is a zoonotic disease and a worldwide public health problem that affects mainly high-risk groups. Characterizing knowledge, attitude, and practice (KAP) among high-risk groups is important to develop appropriate prevention programs. Here, we performed a cross-sectional study among 300 visitors of a recreational forest in Malaysia to examine leptospirosis KAP and demographics. These variables were integrated to create knowledge and practice scores for each respondent. All respondents had heard about leptospirosis, and 87% of them correctly identified it as a disease. The majority of respondents had high knowledge (63%), positive attitude, and good practice (68%) toward prevention of the disease. However, there were gaps in knowledge, with 78% of the respondents indicating eating without washing hands as the major cause of leptospirosis transmission. Our final model identified that higher knowledge score was associated with higher practice score. Our results indicate that it is important to increase knowledge, especially on transmission routes of leptospirosis, among visitors in recreational areas. Moreover, more attention needs to be paid to promote good practice habits among visitors, targeting those at higher risk of being infected by leptospirosis to prevent potential outbreaks in the recreational areas.Thousands of Palestinian and Arab-Israeli pilgrims travel to Mecca each year to complete their pilgrimage. To the best of our knowledge, no previous studies have characterized the infectious and noninfectious morbidity among Arab-Israeli or Palestinian Hajj pilgrims. Thus, we designed and conducted an observational questionnaire-based study to prospectively investigate the occurrence of health problems among these Hajjis who traveled to complete their Pilgrimage during 2019 Hajj season. For the purpose of the study, questionnaires were distributed to Hajj pilgrims at three different time occasions-before travel, inquiring on demographics and medical comorbidities; and 1 and 4 weeks after returning recording any health problems encountered during or after travel. Initial recruitment included 111 Hajjis. The mean age of responders was 49.5 (±9.1) years, with an MF ratio of 1.31. The mean travel duration was 18.7 (13-36) days. Altogether, 66.3% of the pilgrims reported at least one health problem during and after the trip, of which 38.6% sought medical attention. Five (4.8%) hajjis were hospitalized, including life-threatening conditions. Cough was the most common complaint (53.8%), and 11.5% also reported fever. Pretravel counseling was associated with reduced outpatient and emergency room visits. We therefore concluded that a high rate of morbidity was reported among this cohort of Hajj pilgrims with a morbidity spectrum similar to pilgrims from other countries. Pretravel consultation with the purpose of educating the pilgrims on the health risks of Hajj may help reduce the morbidity for future Hajj seasons.In 2016, Sanofi Pasteur (S-P) experienced a manufacturing disruption of yellow fever vaccine (YF-Vax), the only U.S.-licensed YF-Vax, depleting the U.S. supply by mid-2017. Sanofi Pasteur received approval to import Stamaril, S-P's French-manufactured YF-Vax, for use in 260 U.S. civilian clinics under an expanded access investigational new drug program (EAP). The CDC also broadened its YF-Vax indication in early 2018. Our objective was to assess usage at participating Global TravEpiNet (GTEN) clinics, a U.S. CDC-supported national consortium of clinical sites that administer vaccines, during this period of limited availability and changing recommendations. We analyzed 2012-2018 GTEN data for YF-Vax usage, unavailability, and reasons for refusal. We also performed a brief voluntary survey of GTEN sites to better understand their experience during the shortage. Yellow fever vaccine unavailability at certain GTEN clinics was intermittent and recurrent, starting months before total depletion. Unavailability at GTEN clinics peaked weeks before the total depletion. Compared with historic norms, YF-Vax usage following initial vaccine availability limitations did not change until vaccine recommendations were broadened. Refusal of recommended YF-Vax also decreased during this period. Queried sites participating in the EAP felt their supply of vaccine was adequate. Our analysis suggests that in response to depletion of a travel vaccine, an EAP can make an unlicensed product available, patients will participate in such a program, and the program can respond to expanding recommendations for vaccine usage.SARS-CoV-2 is an enveloped non-segmented positive-sense RNA virus, classified as a beta coronavirus, responsible for the COVID-19 pandemic. Angiotensin-converting enzyme 2 (ACE2), reported as a SARS-CoV-2 receptor, is expressed in different human tissues (lung, intestine, and kidney) and in the testis, ovaries, uterus, and vagina. This suggests a potential risk to the human reproductive tract in COVID-19 patients. In addition, SARS-CoV-2 RNA has been detected in the blood, urine, facial/anal swabs, semen, and vaginal secretion, suggesting other potential means of transmission. However, little has been reported about SARS-CoV-2 infection in the male and nonpregnant female reproductive tracts, which may provide direct evidence on sexual transmission and fertility problems. Therefore, we focused this narrative review mainly on the distribution of ACE2 and SARS-CoV-2 positivity in the male and nonpregnant female reproductive tracts, providing an overview of the potential threat of COVID-19 to reproductive health and sexual transmission.Powassan virus (POWV) is a tick-borne virus maintained in sylvatic cycles between mammalian wildlife hosts and ticks (primarily Ixodes spp.). There are two currently recognized lineages, POWV-lineage 1 (POWV-L1) and deer tick virus (DTV; lineage 2), both of which can cause fatal neurologic disease in humans. Increased numbers of human case reports in the northeastern and north central United States in recent years have fueled questions into POWV epidemiology. We inoculated three candidate wildlife POWV reservoir hosts, groundhogs (Marmota monax), striped skunks (Mephitis mephitis), and fox squirrels (Sciurus niger), with either POWV-L1 or DTV. Resulting viremia, tissue tropism, and pathology were minimal in most inoculated individuals of all three species, with low (peak titer range, 101.7-103.3 plaque-forming units/mL serum) or undetectable viremia titers, lack of detection in tissues except for low titers in spleen, and seroconversion in most individuals by 21 days postinoculation (DPI). Pathology was limited and most commonly consisted of mild inflammation in the brain of POWV-L1- and DTV-inoculated skunks on four and 21 DPI, respectively. These results reveal variation in virulence and host competence among wild mammalian species, and a likely limited duration of host infectiousness to ticks during enzootic transmission cycles. However, POWV can transmit rapidly from tick to host, and tick co-feeding may be an additional transmission mechanism. The rare and low-level detections of viremia in these three, common, wild mammal species suggest that vector-host dynamics should continue to be explored, along with eco-epidemiological aspects of enzootic POWV transmission in different regions and virus lineages.The diagnosis of visceral leishmaniasis (VL) is complicated and often unsuspected. Little is known of the usefulness of nuclear imaging in VL. Our objective was to describe findings seen in fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) in cases of VL. We retrospectively reviewed VL cases diagnosed at Vall d'Hebron University Hospital from May 2012 to May 2018 and selected those that had an FDG-PET/CT performed. Information on procedures and details of the FDG-PET/CT features and follow-up were collected. We then systematically reviewed the literature on VL and FDG-PET/CT. Four of 43 patients diagnosed with VL had an FDG-PET/CT performed. All four patients presented diffuse splenic uptake of FDG-PET/CT. Adenopathy was not always present, and bone marrow uptake was found in two patients. A posttreatment FDG-PET/CT in one patient revealed normalization of initial findings. In the literature review, 43 of 50 cases presented similar splenic uptake in the PET/CT, being described as different patterns "increased metabolism," "homogeneous," "diffuse," "diffuse and multifocal," "nodular," "patchy and granular," "subcortical," and "compatible with lymphoma.
