How Does Zika Virus Cause Auditory Loss?

Karen B. Jacobson, MD, MPH, of Kaiser Permanente Northern California, presented data at IDWeek 2026 showing 58.2% of children younger than five years exposed to active hepatitis B in the home were exposed by someone other than their birth mother, a risk maternal screening alone would miss under the CDC’s revised birth dose recommendation.

Labcorp data presented at IDWeek 2026 show measles PCR testing nearly quadrupled and positivity rose sharply from April 2025 through March 2026, as clinicians shift toward guideline-recommended molecular testing amid ongoing US outbreaks.

In this first IDWeek 2026 roundup, oral olorofim matched AmBisome in invasive aspergillosis, aztreonam-avibactam held activity as MBL-producing CRE rose, pritelivir cut hospitalizations in refractory HSV, and zelicapavir shortened RSV symptoms in high-risk adults.

David Altarac, MD, discusses the 2026 IDSA guidance, which prioritizes sulbactam-durlobactam plus a carbapenem for invasive carbapenem-resistant Acinetobacter infections.

Investigational agent Zelicapavir cut time to complete RSV symptom resolution by up to a week and lowered hospitalization in high-risk adults.

Preliminary SABEDTIO data from IDWeek 2026 show early dual IV therapy cut prolonged S aureus bacteremia to 6% from 16%, with safe oral transition at 72 hours.

Alejandra Gurtman, MD, discussed the phase 2 data at IDWeek 2026 which showed the investigational 25-valent pneumococcal conjugate vaccine 25vPnC produced serotype 3 antibody levels about 15-fold higher than Prevnar 20 after the booster dose, targeting a serotype still behind 10.6% of invasive pneumococcal disease in US children younger than five years.

Stopping empiric antibiotics early nearly tripled antibiotic-free days in neutropenic fever, and 5-day oseltamivir prophylaxis matched 10 days in hospital exposures.
