Current treatments for these diseases require long-term annual mass drug administration (MDA) to at-risk populations. Although there have been many success stories utilizing this approach,...

Albendazole tablets used in lymphatic filariasis treatment programs. https://www.flickr.com/photos/prefeituradeitapevi/33462574864 Lymphatic filariasis Lymphatic filariasis, a disease common in tropical and subtropical areas, is spread by mosquitoes and caused by infection with parasitic filarial worms. Once infected, larval worms grow into adult worms and mate to produce microfilariae (mf). The mf are then collected by mosquitoes during a blood meal, and the infection can be spread to another person. Life cycle of parasitic worms causing lymphatic filariasis. Infection can be diagnosed using tests for circulating mf (microfilaremia) or parasite antigens (antigenemia), or by ultrasound imaging to detect live adult worms. The...

First, is higher property crime associated with increased searches for crime prevention? And, if so, are increased searches for crime prevention associated with a reduction in property crime? Finally, if there is a reduction, what is the magnitude of that reduction? To address these challenging research questions, we had to pause and apply some criminological thinking. That is, Google Search Data allows you to upload datasets and merely examine what factors correlate. However, this...

Lymphatic filariasis patient (Copyright: Mark Taylor, Liverpool School of Tropical Medicine) Onchocerciasis (river blindness) and lymphatic filariasis (elephantiasis) are neglected tropical diseases (NTDs) that cause severe disability and affect more than 106 million people, according to the latest reports from WHO. These two NTDs are caused by parasitic roundworms, the filarial nematodes Onchocerca volvulus (onchocerciasis), Wuchereria  bancrofti, Brugia malayi, and Brugia timori (lymphatic filariasis). These diseases have long-term chronic impacts on the health and wellbeing of endemic communities, including economic burden, disabilities, mental health issues and social stigmas.
