	Tracing social and risk networks can help identify undiagnosed cases of HIV Conducting HIV testing among the social and risk networks of those recently diagnosed with HIV helps identify undiagnosed cases of HIV at significantly higher rates and at a lower cost than other testing approaches, finds a new study conducted in Ukraine by an international research team.

	GW study uncovers potential obstacle to finding a cure for HIV The latest "kick-and-kill" research to eliminate the HIV virus uncovered a potential obstacle in finding a cure.

	States face costly conundrum: How to treat inmates with hepatitis C In a corner of Jymie Jimerson’s house in the town of Sparta, in southwestern Missouri, she has set up a kind of shrine.

The review is published in the journal Physiology.

	SUTD-NCL team completes phenotypic screening of MMV Malaria Box against pathogenic parasites A Singapore-India collaborative research project between the Singapore University of Technology & Design and CSIR-National Chemical Laboratories completed phenotypic screening of a large collection of potent chemical inhibitors (known as MMV Malaria Box), against pathogenic parasites Toxoplasma gondii and Plasmodium falciparum, causative agents of human toxoplasmosis and malaria.

	Repurposed drug effectively protects against Zika virus in mouse models In both cell cultures and mouse models, a drug used to treat Hepatitis C effectively protected and rescued neural cells infected by the Zika virus -- and blocked transmission of the virus to mouse fetuses.

	Global effort toward HIV cure published in Special Issue of AIDS Research and Human Retroviruses Researchers have shown that despite effective combined antiretroviral therapy, HIV can hide in the spleen of patients with no detectable HIV in their blood.

	Microbiome research offers new clues to increased HIV risk in women Drawing from data collected for years by AIDS researchers in six African nations, scientists have pinpointed seven bacterial species whose presence in high concentrations may significantly increase the risk of HIV infection in women.
