Researchers at Johns Hopkins say an online "pop quiz" they developed in 2009 shows promising accuracy in predicting sexually transmitted infections (STIs) in young women, although not, apparently, in young men.

Healthcare-acquired infections (HAIs) are among the leading causes of patient disability and mortality as well as financial loss for health care institutions with hundreds of millions of patients affected and the United States losing approximately $6.5 billion annually. Despite efforts to solve the HAI problem, 3.5 percent to 12 percent of patients are affected each year. HAI are often due to factors such as insufficient application of hygienic practices and hospital protocols.(1)

Zika virus is spreading rapidly through the Americas and could potentially reach all countries except Canada and continental Chile, the director of the Pan American Health Organization (PAHO), Dr. Carissa F. Etienne, told health officials from around the world during a briefing of the executive board of the World Health Organization (WHO) in Geneva.

The Molecular Microbiology Research Group in the UAB's Department of Genetics and Microbiology describes for the first time, in a work published in PLOSone, a model of behavior of a bacterial colony that shows how the colony protects itself against toxic substances, like antibiotics, during the colonization process.

A new study published in the Journal of Medical Entomology is the first to report that bed bugs have developed resistance to a class of insecticides known as neonicotinoids, or neonics, the shortened name. Neonics are the most widely used group of insecticides today, and several products have been developed for bed bug control over the past few years that combine neonics with pyrethroids, another class of insecticide.

The World Health Organization's director-general should convene "urgently" a meeting of International Health Regulations' Emergency Committee to advise on the emerging Zika pandemic and galvanize global action, say two Georgetown University professors.

Advances in genetic sequencing are uncovering emerging diseases in wildlife that other diagnostic tests can’t detect. In a study led by Duke University, researchers used a technique called whole-transcriptome sequencing to screen for bloodborne diseases in wild lemurs, distant primate cousins to humans.

The Zika virus, unlike other mosquito-borne viruses such as dengue, is relatively unknown and unstudied. That is set to change since Zika, now spreading through Latin America and the Caribbean, has been associated with an alarming rise in babies born in Brazil with abnormally small heads and brain defects – a condition called microcephaly.
