The saliva of mosquitoes infected with dengue viruses contains a substance that thwarts the human immune system and makes it easier for people to become infected with these potentially deadly viruses, new research reveals.
Getting sick often may impact how quickly the brain ages and increase the risk of dementia or other forms of cognitive decline.
A study by researchers at Washington University School of Medicine in St. Louis shows that vaccinating people with updated boosters as new variants of the virus that cause COVID-19 emerge could shore up population immunity even as the virus mutates, and thereby prevent another deadly COVID-19 wave.
The National Institute of Allergy and Infectious Diseases has awarded a five-year, $15.45 million grant to the San Diego Center for AIDS Research at UC San Diego, renewing support that extends back to an original establishing grant in 1994 at the height of the AIDS epidemic.
Forty per cent of people diagnosed with HIV in Aotearoa between 2011 and 2020 were diagnosed late, a University of Otago study shows.
New research led by Penn State reveals that the stem region of the spike protein became progressively tighter over time, and the team thinks this likely improved the virus’s ability to transmit through nasal droplets and infect host cells once in the body.
In a study among residents of Ventura County, California, rates of sudden cardiac arrest rose sharply during the COVID-19 pandemic.

In a new study, researchers analyzed data from Cali, Colombia, to develop a model that provides a template for tracking data, predicting transmission, and informing health surveillance systems.
Research by the Milner Centre for Evolution at the University of Bath, UK, along with colleagues at Universities of Oxford and Aberdeen, finds that trust in scientists has hugely increased overall since the COVID-19 pandemic, but that attitudes have also become more polarized. The study also found that people were more likely to take the COVID-19 vaccine if their trust in the science had increased.
Researchers found that, despite being heavily immunocompromised, haematology patients generate strong cellular immune responses against SARS-CoV-2 after vaccination, on par with that of healthy individuals.
The seasonal flu vaccine is less effective in some years than others. New St. Jude research showed one reason behind this lack of efficacy is the inclusion of flu strains with an unstable viral protein.
The COVID-19 pandemic posed an immense challenge on the health care industry in 2020 and 2021. While hospitals were inundated with COVID-19 cases, other illnesses such as respiratory syncytial virus (RSV) saw a decrease in hospital visits, particularly in the fourth quarter of 2020 and the first quarter of 2021.
There are no vaccines or therapies available for lymphocytic choriomeningitis virus (LCMV) infection. This pathogen spreads easily and is extremely common in people worldwide.
From septic shock to sticker shock. Keep up with this ever-growing, changing sector. Below are some of the latest stories on healthcare on Newswise.
Researchers have designed a molecule that slows the effects of one of SARS-CoV-2's more dangerous components – an enzyme called a protease that cuts off the immune system's communications and helps the virus replicate. While much more needs to happen to develop a drug, scientists can begin to imagine what that drug could look like – thanks to new images of the molecule bound to the protease.
Wistar Institute researchers identified hopeaphenol, a natural plant-based compound, as possessing antiviral properties that are effective against HIV.
Countries must intensify efforts to track HIV and hepatitis C virus (HCV) incidence among people who inject drugs, and to prioritise this group in prevention and elimination work, according to new University of Bristol-led research, published online in The Lancet Gastroenterology & Hepatology.
Scientists report using a single-atom-thick nanomaterial to build a device that can simultaneously detect the presence of the viruses that cause COVID-19 and the flu — at much lower levels and much more quickly than conventional tests for either. They will present their results at ACS Spring 2023.
While COVID-19 can be transmitted via contact with contaminated objects, most studies have focused on airborne droplet transmission.
A quick, affordable diagnostic test developed by a Washington State University researcher may help curb one of the most prevalent but least discussed sexually transmitted infections.
You might have heard or read about the ‘superbug’ Candida auris (C. auris), but is it as scary as the news makes it seem?
A new study identified a compound that prevents C. diff infection. Researchers are now using this compound to develop new drug candidates that might eventually offer a way to prevent serious C. diff infections.
New research from Boston Medical Center found that substance use disorders do not increase the likelihood of dying from COVID-19. Published in Substance Abuse: Research and Treatment, the study showed that the increased risk for severe COVID-19 in people with SUD that has been seen may be the result of co-occurring medical conditions.
Heated tobacco products—an alternative to traditional cigarettes, similar to e-cigarettes or vapes—do not burn tobacco leaves, but rather allow users to inhale the vapor produced by heating the tobacco leaves.
Researchers have developed a molecule that is, when administered nasally, extremely effective in preventing the disease caused by all known variants of the SARS-CoV-2 virus.
For mosquito-borne diseases such as dengue fever, the abundance of the insects in places where people gather has long served as the main barometer for infection risk. A new study, however, suggests that the number of “hidden” infections tied to a place, or cases of infected people who show no symptoms, is the key indicator for dengue risk.
The Centers for Disease Control and Prevention issued an alert that infections from the fungus Candida auris are increasing. Theresa O’Meara, Ph.D., an assistant professor in the Department of Microbiology & Immunology at the U-M Medical School, speaks about the emerging threat.
People infected with SARS-CoV-2, the virus that causes COVID-19, may experience genome structure changes that not only may explain our immunological symptoms after infection, but also potentially link to long COVID, according to a new study by researchers at UTHealth Houston.
Rutgers New Jersey Medical School will receive $20 million over five years from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, to coordinate research being conducted in eight nations on tuberculosis (TB) control and prevention.

Post-acute sequelae SARS-CoV-2 infection (PASC), also known as long-haul COVID-19, is positively associated with posttraumatic stress disorder (PTSD), says new research presented at Physiatry ’23, the Association of Academic Physiatrists (AAP) annual meeting.
Global data shows nearly 10 per cent of severe COVID-19 cases involve a secondary bacterial co-infection – with Staphylococcus aureus, also known as Staph A., being the most common organism responsible for co-existing infections with SARS-CoV-2.
A UCLA-led team has developed an inexpensive, universal oral COVID-19 vaccine that prevented severe respiratory illness and weight loss when tested in hamsters, which are naturally susceptible to SARS-CoV-2. It proved as effective as vaccines administered by injection or intranasally in the research. If ultimately approved for human use, it could be a weapon against all COVID-19 variants and boost uptake, particularly in low- and middle-income countries, and among those with an aversion to needles.
Human papillomaviruses (HPVs) cause several cancers in both men and women, including 91% of cervical cancers, 91% of anal cancers and 75% of vaginal cancers, according to the Centers for Disease Control and Prevention. Most of these cancers are caused by just a handful of HPV virus types.
Malaria control programs in Amazonian Peru helped reduce the incidence of the deadly parasitic disease by 78 percent. That is, until the programs ceased to operate.
