BACKGROUND: Before searching prior records, sexually transmitted disease (STD) programs use syphilis reactor grids to exclude some reactive non-treponemal test results (RNTs) based on patient age, sex, and test titer. We propose a new algorithm that starts with comparing RNTs to previous syphilis non-treponemal tests and current treponemal test results. METHODS: De-duplicated RNTs from Florida's surveillance system (2006-2015) were extracted and stratified on morbidity...

Since June 2016, an outbreak of hepatitis A has been reported in Europe. Here we report the HAV outbreak in Brescia (Northern Italy) from July 2016 to July 2017. We actively recorded all HAV cases defined by detection of HAV IgM antibodies in serum. Data on sexual behaviour, travel attitudes, concomitant sexually transmitted diseases (STDs), clinical presentation and laboratory results were collected. Forty-two confirmed cases were recorded: 25 (60%) were MSM and reported sexual contact at risk of STDs. Compared to 2015 and the first half of 2016, when only three hepatitis A cases were recorded, in the 12 months in question the number of cases rose 14-fold...

Ticks are important disease vectors as they transmit a variety of human and animal pathogens worldwide. Symbionts that co-evolved with ticks confer crucial benefits to their host in nutrition metabolism, fecundity and vector competence. Although over a hundred-tick species have been identified in China, general information of tick symbiosis is limited. Here, we visualized the tissue distribution of Coxiella sp. and Rickettsia sp. in lab reared Haemaphysalis longicornis and Rhipicephalus haemaphysaloides by fluorescent in situ hybridization...

Zika virus is a flavivirus primarily transmitted to humans by Aedes aegypti mosquitoes (1). Zika virus infections also have been documented through intrauterine transmission resulting in congenital infection; intrapartum transmission from a viremic mother to her newborn; sexual transmission; blood transfusion; and laboratory exposure (1-3). Most Zika virus infections are asymptomatic or result in mild clinical illness, characterized by acute onset of fever, maculopapular rash, arthralgia, or nonpurulent conjunctivitis; Guillain-Barré syndrome, meningoencephalitis, and severe thrombocytopenia rarely have been associated with Zika virus infection (1)...

We present a dual-wavelength polarimetric measurement method to distinguish species and sexes of disease transmitting mosquitoes in flight. By measuring co- and de-polarized backscattered light at 808 and 1550 nm, the degree of linear polarization, wingbeat frequency, reflectance, spectral ratio and glossiness of mosquitoes can be retrieved. Body and wing contributions to these signals can be separated. Whereas the optical cross-section is sensitive to the aspect of observation, thus the heading direction of the insect in flight, we demonstrate that polarimetric- and spectral- band ratios are largely invariant to the aspect of observation...

Syphilis is a resurgent sexually transmitted infection in the UK that is disproportionately diagnosed in patients living with HIV, particularly in men who have sex with men. Syphilis appears to present differently in patients with HIV, particularly in those with severe immunosuppression. Progression to neurosyphilis is more common in HIV coinfection and can be asymptomatic, often for several years. The presentations of neurosyphilis vary but can include meningitis, meningovascular disease, general paresis and tabes dorsalis...

BACKGROUND: Mosquito-borne diseases are rapidly spreading to vast territories, putting at risk most of the world's population. A key player in this scenario is Aedes aegypti, a hematophagous species which hosts and transmits viruses causing dengue and other serious illnesses. Since vector control strategies relying only on insecticides have proven unsustainable, an alternative method involving the release of Wolbachia-harboring individuals has emerged. Its successful implementation vastly depends on how fit the released individuals are in the natural habitat, being able to mate with wild populations and to spread Wolbachia to subsequent generations...

BACKGROUND: Antiretroviral (ARV) medicines reduce the risk of transmitting the HIV virus and are recommended as daily pre-exposure prophylaxis (PrEP) in combination with safer sex practices for HIV-negative individuals at a high risk for infection, but are underused in HIV prevention. Previous literature suggests that YouTube is extensively used to share health information. While pre-exposure prophylaxis (PrEP) is a novel and promising approach to HIV prevention, there is limited understanding of YouTube videos as a source of information on PrEP...

BACKGROUND: Sexually transmitted diseases (STDs) are increasing among gay, bisexual, and other men who have sex with men (MSM). Little is known about the use of websites and mobile phone applications to meet sexual partners ("hookup sites") and association with STD diagnoses. METHODS: We performed a demographic and behavioral assessment of 415 MSM presenting to the Rhode Island STD clinic. Bivariate and multivariable analyses assessed associations between using hook up sites and testing positive for syphilis, gonorrhea, or chlamydia...

Hepatitis E virus (HEV) is a feco-orally transmitted pathogen and one of the most common cause of acute hepatitis worldwide. Recent studies in developed countries suggested that a direct human-to-human contact such as for sexually transmitted diseases may play a significant role in the HEV spread. The aim of this study was to investigate the seroprevalence of HEV and HAV in a group of MSM, including subjects HIV and Treponema infected, in Milan, Italy. The overall anti HEV IgG seroprevalence in MSM was 10.2% (65/636), instead in the control group the detection rate was 5...
