Washington’s hepatitis C elimination initiative improves treatment access, reduces costs

It took less than 22 years after the discovery of the hepatitis C virus (HCV) for a fast-acting, highly effective treatment to become available.

Antisense oligonucleotides reverse rare neurodevelopmental disorder in preclinical models

Scientists at St. Jude Children's Research Hospital have found they can reverse the effects of HNRNPH2-related neurodevelopmental disorder using antisense oligonucleotides (ASOs) in preclinical models. ASOs are short synthetic nucleic acid strands that target specific messenger RNA.

COVID-19 virus not retained in placenta after maternal recovery

A new Yale study published in JAMA Network Open finds that the virus that causes COVID-19 does not linger in placental tissue weeks to months after a pregnant woman recovers from infection - offering important reassurance for clinicians and patients alike.

Rising rotavirus cases highlight importance of childhood vaccination

With a rising number of rotavirus cases being reported across the country and in New Jersey this spring, experts from Hackensack Meridian Children's Health are urging parents to ensure their children are vaccinated against this common and potentially severe illness.

Scientists develop MIND approach to predict and reshape microbiomes

University of California San Diego researchers have developed a new tool for understanding and modifying any microbiome, including the human microbiome.

New mechanism disables antibiotic resistance and cross-protection in bacteria

A newly discovered mechanism renders antibiotic-resistant bacteria vulnerable by disabling both their individual resistance and a process known as cross-protection, the ability of resistant bacteria to shield nearby, otherwise sensitive strains.

Study creates genetic roadmap of how HIV virus interacts with human cells

The human immunodeficiency virus (HIV), which is the cause of AIDS, is a master of deception, using just nine genes to hijack the complex cellular machinery of the human body.

WHO-recommended antibiotics ineffective for many neonatal sepsis cases

A major multi-country study has found that WHO-recommended first-line antibiotics for neonatal sepsis are likely to be effective in only one quarter of infections in low- and middle-income countries (LMICs).

Study finds no benefit of stronger antibiotics for sinusitis

Acute sinusitis leads to more antibiotic prescriptions for U.S. adults than any other condition, but there is no consensus on which antibiotic is preferred for uncomplicated cases.

Simple oral care cuts hospital-acquired pneumonia risk

A landmark trial presented today at ESCMID Global 2026 shows that improving oral hygiene for hospital patients can reduce the risk of non-ventilator-associated hospital-acquired pneumonia (NV-HAP) by 60%.

Why Japan saw a major pertussis surge in 2025 while other countries peaked earlier

This study found that pertussis cases fell across Japan, Australia, New Zealand, China, and the USA during COVID-19 restrictions, then resurged afterward, with most countries peaking in 2024 but Japan showing a delayed major outbreak in 2025. In Japan, the surge was concentrated in school-aged children and adolescents, highlighting possible gaps in booster protection and the need to reassess immunization strategies.

Certain prenatal medications linked to increased risk of autism

A landmark study led by researchers at the University of Nebraska Medical Center (UNMC) and published in Molecular Psychiatry has identified a significant association between prenatal prescription of commonly utilized medications and the risk of autism spectrum disorder (ASD) in children.

Newborns carry antibiotic resistance genes within first hours of life

Antibiotic resistance genes (ARGs) – segments of DNA that help bacteria survive the effects of antibiotics – can be present in newborns within the first hours of life, according to research presented at ESCMID Global 2026.

Antiretroviral therapy reduces biological aging in people living with HIV

A major study presented today at ESCMID Global 2026 has found that antiretroviral therapy (ART) reduces accelerated biological ageing in people with HIV (PWH) by nearly four years, a finding that could transform how clinicians monitor HIV treatment and long-term health outcomes.

Study reveals significant gaps in MMR vaccine knowledge among ER patients

Measles remains one of the most contagious infectious diseases, spread through coughing and sneezing, with even small declines in vaccination coverage leading to outbreaks. As of 2026, California has reported its highest annual measles case count in seven years. In response to this growing concern, researchers have begun examining gaps in measles-related knowledge and vaccination coverage.

New handbook aims to improve pandemic modeling and decision making

As the COVID-19 pandemic wreaked havoc and lives were at stake, the advice experts gave to decision-makers became indispensable.

Researchers discover how stress signals weaken the aging immune system

As we age, our ability to maintain healthy blood and a strong immune system gradually declines, largely because hematopoietic stem cells (HSCs), the cells responsible for producing all blood cell types, begin to lose their effectiveness. Normally, HSCs can both self-renew and generate a balanced mix of blood cells, but over time they produce fewer new cells, favor certain cells such as myeloid cells over lymphoid cells, and struggle to support a robust immune response.
