Histoplasma, Blastomyces, and Coccidioides remain underrecognized causes of community-acquired pneumonia, particularly when clinical presentation mimics bacterial disease. Knowing where to look and when reshapes the diagnostic and therapeutic approach.

The US childhood vaccine schedule was the big news this month with the presidential executive order making changes to it as well as the latest Centers for Disease Control and Prevention kindergarten immunization numbers for the 2025-2026 year. Learn more about the news with clinician commentary and how it might impact patient care.

This week's top infectious disease stories cover treatment strategies for daptomycin-resistant Enterococcus faecium, fluoroquinolone prescribing's link to antimicrobial resistance, the legal standing of the childhood vaccine schedule executive order, and rising vaccine exemption rates alongside declining MMR coverage that's fueling continued measles outbreaks.

Newly released CDC data show childhood immunization rates have steadily declined since 2020, pushing measles vaccination coverage below the threshold needed for herd immunity and leaving an estimated 280,000 kindergartners without documented vaccinations this year. Robert Hopkins Jr, MD, medical director of the National Foundation for Infectious Diseases, discusses the latest vaccine data, geographic patterns, and how public health and school officials can address this continued trend.

Fluoroquinolone prescribing emerged as key driver of AMR in multiple pathogens in a 14-year study period at US Veterans Affairs medical centers.

Cases and deaths continue to increase in the Democratic Republic of the Congo, but the country's neighbor, Uganda, is declared Ebola free.

With the news this week that childhood vaccine exemptions were at a historical high, it is important to understand what they are and how they are applied. Pediatrician Sharon Nachman, MD, offers some insights about the ability to forgo vaccines because of exemptions.

As of August 17, federal officials are reporting more than 15, 716 cases, hundreds of hospitalizations, and nearly all US states have been affected.

The latest national numbers show a decrease in vaccination rates, along with a spike in the number of immunization exemptions, leading to an increase in the number of cases for vaccine-preventable diseases such as measles.

In the second episode with Jason M. Goldman, MD, MACP, he touches upon the legal side of the order and how it may affect the childhood vaccine schedule.

FDA has assigned its highest-risk Class I classification to a recall of nearly 19 million eggs linked to a multistate salmonella enteritidis outbreak that has sickened 98 people across 17 states.

Daptomycin-resistant Enterococcus faecium bacteremia is an emerging, high-mortality challenge in transplant and other high-risk patients, requiring early recognition, aggressive source control, and reliance on limited alternatives—most notably linezolid—with combination or salvage therapies considered when options are constrained.

This week's infectious disease news spans a broad-spectrum carbapenem review, an expanding jalapeño-linked salmonella recall, the EU approval of Maviret for acute hepatitis C, and clinician backlash against President Trump's executive order reshaping the childhood vaccine schedule.

In the second part of the interview with Sharon Nachman, MD, she touches upon how the administration’s shared clinical decision-making category related to childhood vaccines will affect the hepatitis B and rotavirus vaccines and the expectations there will be subsequent disease increases.

Jason M. Goldman, MD, MACP, discusses the potentially damaging effects of the rhetoric coming from the presidential executive order, including downstream consequences and his concerns about the prospective findings of the HHS Task Force on Safer Childhood Vaccines associated with the order.

The presidential executive order changing the measles, mumps and rubella (MMR) vaccine from a combination to a single-antigen vaccine means children will get more shots not less. Sharon Nachman, MD, offers some insights around the challenges of how the order’s latest changes could affect pediatric vaccine schedules.

The EU recently approved glecaprevir/pibrentasvir (Maviret), an eight-week direct-acting antiviral regimen, which offers people with hepatitis C the fastest treatment option available, giving European health systems a new tool in aiding the World Health Organization's goal of eliminating the virus by 2030.
