No Antibiotic In The U.S. Could Save This Woman. We Should All Be Worried.

This is one of the first cases of a pan-resistant infection in America.

The recent death of a woman in Reno, Nevada, from an infection resistant to every available kind of antibiotic in the U.S. highlights how serious the threat of antibiotic-resistant superbugs has become. 

Experts say that while cases of a bacteria resistant to all antibiotics are still extremely rare in the U.S., we should expect to see more in the future.

A case study reports evidence of viral replication lingering in the respiratory tract of an infected person, even after their blood was Ebola free.

Ebola virus may linger and continue to replicate in the lungs of patients recovering from infection, even after viral RNA is no longer detectable in their bloodstreams, according to a case study published today (January 5) in PLOS Pathogens. . . .

 . . . Ippolito and his colleagues monitored the Ebola-infected patient, who was moved from West Africa to a hospital in Italy in 2015, over the course of their infection. They found viral RNA and other markers of viral replication in the patient’s lungs five days after such markers were no longer detectable in the blood.

Mosquito-borne diseases like Zika can be extremely sensitive to climatic changes

The combination of climate change and last year’s El Niño phenomenon likely created the perfect playground for the Zika virus to spread rapidly across South America, a new study finds.

Both the Zika virus and the mosquitoes that carry it have been present in different parts of the world for a while. But several factors, including specific climatic conditions, could have catapulted the disease to public health emergency status, according to researchers from the University of Liverpool.

In this report based on preliminary data for pregnant women in the USZPR with laboratory evidence of possible Zika virus infection, 6% overall had a fetus or infant with evidence of a Zika-related birth defect, and among women with timing of possible Zika infection exclusively during the first trimester, 11% had a fetus or infant with a birth defect. The birth defects primarily involved included microcephaly with brain abnormalities, such as intracranial calcifications. Preliminary estimates from the USZPR were within the range of 1% to 13% risk of microcephaly following first-trimester maternal Zika virus infection modeled on the outbreak in Bahia, Brazil, lending support to the credibility of these estimates.
