Schistosoma mattheei and zoonotic schistosomiasis.

We highlight the epidemiological importance of Schistosoma mattheei, a common parasite of livestock with an underappreciated ability to infect people, being recently incriminated in both female and male genital schistosomiasis. Through hybridisation(s) with other schistosome species, its public health importance will grow as its zoonotic potential expands across southern Africa.

RSV and rhinovirus increase pneumococcal carriage acquisition and density, whereas nasal inflammation is associated with bacterial shedding.

Epidemiological studies report the impact of co-infection with pneumococcus and respiratory viruses upon disease rates and outcomes, but their effect on pneumococcal carriage acquisition and bacterial load is scarcely described. Here, we assess this by combining natural viral infection with controlled human pneumococcal infection in 581 healthy adults screened for upper respiratory tract viral infection before intranasal pneumococcal challenge. Across all adults, respiratory syncytial virus (RSV) and rhinovirus asymptomatic infection confer a substantial increase in secondary infection with pneumococcus.

Highlighting male genital schistosomiasis in Malawi.

Highlighting recent literature, we review the epidemiological and clinical importance of male genital schistosomiasis (MGS) in Malawi. We then discuss why individual disease management is an unmet public health challenge and outline how future interventions should be better set within routine services of HIV and men's sexual and reproductive health clinics.

Prospective pilot study on the relationship between seminal HIV-1 shedding and genital schistosomiasis in men receiving antiretroviral therapy along Lake Malawi.

Male genital schistosomiasis (MGS) is hypothesized to increase seminal shedding of HIV-1. This prospective pilot study assessed seminal HIV-1 RNA shedding in men on long-term ART with and without a diagnosis of MGS. Study visits occurred at 0, 1, 3, 6 and 12 months.
