Zika Infection Through Sexual Transmission

Signs of Zika infection can be seen in semen for as long as nine months, but the risk of sexual transmission appears to end in one month, according to a study published Wednesday. The study suggests health officials have been overly cautious in advising couples to abstain from sex or to use condoms for at least six months after a male partner comes down with Zika. The study was published online in the New England Journal of Medicine.

Preprints — scientific manuscripts that are posted at a recognized online repository before peer review — have the potential to speed up the reporting of scientific research in infectious disease outbreaks, argue Michael Johansson and colleagues in an Essay in PLOS Medicine: "The scientific community should not ask why preprints are posted during outbreaks, we should ask why they are not posted…."

Leishmaniasis Strain identified in Iraq

In the hot, dry border region between northern and central Iraq, Leishmania parasite infections are so common that they have been dubbed 'Baghdad sores.'

High Rate of Neonatal Infections in Madagascar, Study finds

Every year in the world, 4 million children die before the age of one, mainly in resource-limited countries, one-third of them due to a severe infection. The neonatal period alone (first month of life) accounts for one-third of deaths before the age of one. This situation is all the more complex in a context of the ever-increasing emergence of antibiotic-resistant bacteria.

In 2012, the Institut Pasteur and Institut Pasteur de Madagascar initiated the BIRDY program with the aim of documenting neonatal infections in the community and assessing the state of antibiotic resistance.
