Skin explants reveal how Ebola virus moves through the body

Ebola is a deadly hemorrhagic disease caused by a virus that is endemic in parts of East-Central and West Africa. Most people are aware that a primary route for person-to-person transmission is through contact with bodily fluids from an infected person.

Scientists pinpoint regions and species fueling coronavirus evolution in bats

Study uncovers the evolution, transmission, and geographic spread of bat coronaviruses in China, revealing key insights into hotspots and the origins of SARS-CoV-2.

Immunocompromised adults show weaker response to RSV vaccines

Johns Hopkins Medicine researchers have shown that people 60 years or older with weakened immunity - primarily organ transplant recipients who take immunosuppressive medications to reduce the risk of rejection and others with immune system disorders - do not respond as strongly to vaccines against the respiratory syncytial virus (RSV) as people in the same age group with normal immune function.

Emergence of FC428 clone and the global spread of ceftriaxone-resistant gonorrhea

Neisseria gonorrhoeae, responsible for the sexually transmitted infection gonorrhea, is becoming increasingly difficult to treat as the pathogen has developed resistance to multiple antibiotics.

WHO TAG-CO-VAC reviews COVID-19 vaccine effectiveness and antigen composition

The WHO Technical Advisory Group on COVID-19 Vaccine Composition (TAG-CO-VAC) continues to closely monitor the genetic and antigenic evolution of SARS-CoV-2 variants, immune responses to SARS-CoV-2 infection and COVID-19 vaccination, and the performance of COVID-19 vaccines against circulating variants.

New MRI method may predict heart disease risk by analyzing heart fat

Everyone knows the health risks of carrying too much fat around the waist and hips, but UVA Health scientists are developing a noninvasive way to assess the health risks of unseen fat around the heart.

RSV vaccine acceptance grows amidst rising flu concerns

A year after becoming available, vaccines to protect against RSV in newborns and older adults are being more widely accepted by the American public, according to a new Annenberg Public Policy Center (APPC) health survey conducted in November 2024.

New research project aims to uncover molecular factors behind malaria’s deadliest strain

Nearly half the world's population lives in regions where malaria is endemic, with the parasite Plasmodium falciparum accounting for approximately 95% of malaria-related deaths globally.

Solving a decades-long puzzle in leishmaniasis drug development

A breakthrough in understanding how a single-cell parasite makes ergosterol (its version of cholesterol) could lead to more effective drugs for human leishmaniasis, a parasitic disease that afflicts about 1 million people and kills about 30,000 people around the world every year.

New insights into respiratory syncytial virus and prevention strategies

Respiratory syncytial virus (RSV) is a major cause of respiratory infections, particularly in infants, children under 5 years, and older adults. Its rapid spread makes RSV a serious public health concern. Currently, there are no effective medications for RSV, and current treatment focuses on providing supportive care and preventing its spread.

Rwanda successfully controls Marburg virus outbreak

An outbreak of Marburg Virus Disease (MVD) in Rwanda has officially been declared over by the Government of Rwanda, with no new cases recorded since the last patient tested negative on 7 November 2024, according to the World Health Organization (WHO).

Host heterogeneity increases pathogen virulence in metapopulations

Heterogeneity is ubiquitous in real-world host populations, yet most theories assume homogeneity. Using a metapopulation model, we examine how host heterogeneities, such as uneven movement patterns and local productivities, affect the evolution of pathogen virulence.

Shiitake-based supplement may help prevent liver damage progression

AHCC demonstrates potential in preventing liver fibrosis progression by inhibiting HSC activation and regulating key pathways involved in liver injury.

Public health strategies essential for reducing airborne virus transmission

Half a decade on from the start of the COVID-19 pandemic, a study by the University of Surrey highlights the significant impact of combined public health measures in reducing airborne viral transmission.

A scaffolded vaccine approach for broader influenza protection

Most people who get the seasonal influenza vaccine – which contains strains of viruses from distinct virus subtypes – mount a strong immune response to one strain, leaving them vulnerable to infection by the others, and researchers have long wondered what impacts such variable responses more – host genetics or prior exposure to virus strains.
