Climate change is warming weather and driving insect populations into new territories. Areas like North America and Europe can expect to see more infections from insect bites.

Mosquitoes and ticks can spread multiple harmful illnesses through bites, including Lyme disease, malaria, dengue, anaplasmosis, babesiosis, and West Nile virus. These illnesses can cause lasting health problems if not treated early.

Fortunately, new research from Acadia University may provide improved protection from tick bites. The Acadia researchers discovered that lemongrass essential oil can block a tick’s ability to detect humans.

The discovery could lead to more effective, natural alternatives to synthetic repellents like DEET. While DEET is widely used, it carries potential risks for skin irritation and environmental harm.

Lemongrass oil, by contrast, is both natural and environmentally friendly. The oil appears to mask human scent and confuse ticks’ sense of smell.

A new vaccine offers strong promise against H5N1 bird flu. The clade 2.3.4.4b virus has spread across North America. Bird flu threatens livestock, birds, and human health. New mutations raise serious pandemic concerns.

Researchers developed a nanoparticle vaccine using viral surface proteins. H5 and N1 proteins were displayed on immunogenic liposomes. These proteins help trigger a strong immune response in the body.

Mice received the vaccine and produced antibodies targeting both proteins. All vaccinated mice survived a deadly H5N1 infection. These results suggest the vaccine offers complete protection.

Climate change is helping dangerous diseases spread across the Arctic. Scientists say rising temperatures are melting permafrost and damaging ecosystems. These changes open new paths for infections to move from animals to people.

An international research team published the findings in Science of the Total Environment. The study shows how warming is reshaping Arctic life. New roads, industries, and people now reach once-isolated areas. This raises the risk of infections like brucellosis, tularemia, and E. coli.

CDC advisors voted to lower the minimum age for RSV vaccination. Adults aged 50 to 59 with risk factors may now qualify. The Advisory Committee on Immunization Practices, or ACIP, voted 14-0 in favor. One member voted to abstain.

The recommendation targets adults at high risk of severe RSV symptoms. Qualifying conditions include heart disease, diabetes, asthma, COPD, chronic bronchitis, kidney disease, weakened immunity, and neurological disorders. These health issues are common in people over 50.

A deadly fungus called Candida auris is spreading in U.S. hospitals. New research shows a major jump in cases since 2019. Only five infections were reported in the United States that year. By 2023, the number of cases jumped sharply to 115.

The fungus kills one in three people who become infected. It targets the elderly and people already sick or hospitalized. Experts say the spread is a growing threat to public health.

Scientists at the University of Pittsburgh have tested a new anthrax treatment. The treatment uses growth factors to help repair damaged lung tissue. It reversed advanced damage in mice with late-stage anthrax infections. This discovery could help patients who miss the usual treatment window.

Anthrax is caused by a bacterium called Bacillus anthracis. It can enter the body through the lungs, skin, or digestion. Early symptoms often look like the flu, making diagnosis difficult. Without fast treatment, anthrax becomes deadly within just a few days.

The new study offers hope for treating advanced or missed infections. Researchers believe this method could save lives in real-world outbreaks.

Walking pneumonia cases are rising this year, especially among young children. The increase is linked to bacteria called Mycoplasma pneumoniae. These bacteria often cause mild respiratory illnesses, including walking pneumonia. While mild, walking pneumonia can still cause persistent and uncomfortable symptoms.

Cold water immersion (CWI) is a growing health and wellness trend. People have used ice baths and cold showers for generations. Modern culture now promotes them as performance therapy and self-care.

A new study in PLoS One reviewed the effects of CWI. The study found that CWI reduces inflammation and stress for a short time. It also boosts immunity, sleep quality, and overall well-being.

The U.S. is facing its worst flu season in 15 years. At least 24 million flu cases have been reported this season. Since October, hospitals have treated up to 650,000 flu patients. This is the highest hospitalization rate since 2017.

Flu season often peaks in January and February. Experts warn that cases could keep rising in the coming weeks.
