Research highlights global economic burden of norovirus

While norovirus is often linked in the news to outbreaks on cruise ships, the highly contagious stomach bug sickens nearly 700 million around the world every year and results in roughly $4.2 billion in health care costs and $60.3 billion in societal costs annually, new Johns Hopkins Bloomberg School of Public Health research suggests.

New study on retroviral DNA could help improve treatments for HIV infection

When retroviruses such as HIV infect a cell, they first make a copy of their RNA genome in the form of DNA. The relatively short viral DNA strand then moves to the cell nucleus, where it inserts itself into the host cell's DNA.

TSRI study reveals important traits in LCMV, Lassa virus

For the first time, scientists at The Scripps Research Institute (TSRI) have solved the structure of the biological machinery used by a common virus to recognize and attack human host cells.

Zika virus present in Americas prior to first identification in Brazil

The Zika virus was present in Haiti several months before the first Zika cases were identified in Brazil, according to new research by infectious-disease specialists at the University of Florida.

TGen scientists trace likely origins, dispersal of fungus that causes Valley Fever

Using the latest in genomic analysis technologies, scientists at the Translational Genomics Research Institute have tracked the likely origins and dispersal of the fungus that causes Valley Fever, according to a study published today in the journal mBio, the premiere journal for reporting high impact microbiological research.

WHO reminds Angola travellers to receive yellow fever vaccination

As efforts to bring an outbreak of yellow fever in Angola under control continue, the World Health Organization is reminding all travellers to the country that they are required to receive the yellow fever vaccination and to have a valid certificate of vaccination to prove that they are protected from the disease and to prevent its further spread.

Regular aspirin use may help reduce risk of bile duct cancer

Regular use of aspirin was linked with a significantly reduced risk of developing bile duct cancer, also called cholangiocarcinoma, in a recent study. The findings, which are published in the journal Hepatology, indicate that additional research on the potential of aspirin for preventing bile duct cancer is warranted.

Newly discovered hybrid house mosquitoes could be bridge vectors between birds and humans

The team of researchers from the Institute of Parasitology at Vetmeduni Vienna sampled nearly 1,500 house mosquitoes in eastern Austria. The northern house mosquito Culex pipiens, representing more than 90% of the total catch, was the most abundant. Culex pipiens comprises a complex of ecologically different forms that are morphologically indistinct.

First-ever vaccine to combat Leishmaniasis under development

As scientists scramble to get a Zika virus vaccine into human trials by the end of the summer, a team of researchers is working on the first-ever vaccine to prevent another insect-borne disease - Leishmaniasis - from gaining a similar foothold in the Americas.

Administering flu vaccinations in the morning could induce greater antibody responses

New research from the University of Birmingham has shown that flu vaccinations are more effective when administered in the morning.

Study highlights potential emergence of new swine flu strains

The wide diversity of flu in pigs across multiple continents, mostly introduced from humans, highlights the significant potential of new swine flu strains emerging, according to a study to be published in eLife.

New blood treatment technology could reduce malaria risk following blood transfusions

Patients, especially children, who undergo blood transfusions in sub-Saharan Africa are at high risk of transfusion-transmitted malaria. A new trial, published in The Lancet today, suggests that treating donated blood with a new technology that combines UV radiation and vitamin B is safe and could minimise the risk of malaria infection following blood transfusions.

Rituximab outperforms fingolimod after natalizumab switch

Rituximab is more effective and better tolerated than fingolimod for patients with multiple sclerosis needing to switch from natalizumab due to JC-virus antibody positivity, research suggests.

Resolving HBV infection does not reduce liver cancer risk

Long-term infection with hepatitis B virus (HBV) can cause liver inflammation and increase the risk of liver cancer. Researchers from the US Centers for Disease Control and Prevention, however, found that resolving HBV infection was not associated with reduced rates of liver cancer.

Lab-grown mini-brains shed light on health crisis posed by Zika virus in fetal brains

Studying a new type of pinhead-size, lab-grown brain made with technology first suggested by three high school students, Johns Hopkins researchers have confirmed a key way in which Zika virus causes microcephaly and other damage in fetal brains: by infecting specialized stem cells that build its outer layer, the cortex.

Decrease in serum zinc levels may cause inflammation among HIV positive individuals

In a new study, University of Massachusetts Amherst researchers Krishna Poudel and colleagues report that zinc deficiency may contribute to chronic inflammation among HIV-positive individuals. Theirs is believed to be the first investigation to explore the association between serum zinc levels and inflammation among people with human immunodeficiency virus (HIV) infection, while taking their anti-retroviral therapy (ART) into account.

Rituximab drug more effective than fingolimod for patients with highly active multiple sclerosis

A new study indicates that rituximab is more effective than fingolimod for preventing relapses in patients with highly active multiple sclerosis switching from treatment with natalizumab.

Infected mice can be better models for human diseases

Vaccines and therapeutics developed using mice often don't work as expected in humans. New research at Washington University School of Medicine in St. Louis points to the near-sterile surroundings of laboratory mice as a key reason.

Researchers develop fine-scale global map of Zika virus transmission

The southeastern US, including much of Texas through to Florida, have ideal conditions for spread of Zika virus according to a new study published in eLife.

Scientists develop new strategy to combat wide range of viruses

Scientists and health officials are marshalling forces to fight Zika, the latest in a string of recent outbreaks. Many of these efforts target that virus specifically, but some researchers are looking for a broader approach. Now one team reports in ACS' journal Macromolecules a new strategy to fight a wide range of viruses that appears to be safe in vivo and could evade a virus's ability to develop resistance.
