Tuberculosis Stages a Modern Comeback in the U.S., Raising Drug-Resistance Fears

Tuberculosis Stages a Modern Comeback in the U.S., Raising Drug-Resistance Fears

TB is resurging in the United States, with provisional 2025 data showing 10,260 cases nationwide (967 in New York). The disease often exists as latent infections (up to 13 million nationwide) that can activate, fueling spread and antibiotic resistance (589 cases resistant to at least one frontline drug in 2023). Active and latent TB require long antibiotic regimens (6–9 months), and early detection plus vaccination considerations are key to prevention. Globally TB remains one of the deadliest infectious diseases, underscoring the ongoing public-health challenge in America and beyond.

Omicron offshoot BA.3.2 spreads across 25 states, vaccine protection under review

A newly identified Covid variant, BA.3.2, is spreading in the United States with evidence from travelers and wastewater tests across at least 25 states. Descended from Omicron and carrying many spike-protein mutations, it may evade protection from current vaccines. While not yet dominant or associated with more severe disease, scientists warn that vaccines might need updating and continued surveillance is essential.

New Covid variant BA.3.2 spreads to 25 states, raising vaccine protection questions

A new Covid variant, BA.3.2, has been detected across the United States, with cases identified in travelers and widespread wastewater signals in at least 25 states. Early data suggest it may partially evade antibodies from current vaccines, though it has not been shown to cause more severe disease; health authorities say vaccine updates may be needed and ongoing surveillance is essential as thousands of Covid deaths continue this year.

Tuberculosis makes a quiet comeback in the United States

Vox’s Future Perfect reports that tuberculosis is rising in the United States as latent infections awaken into active disease, with outbreaks surfacing in places like Archbishop Riordan High School in San Francisco, Long Island, and Seattle. The piece argues that TB remains a global health threat and that domestic progress depends on a strong public-health infrastructure, timely diagnosis, access to preventive therapy, and sustained funding for research and treatment. Delays, drug shortages, and the high cost of care threaten prevention and risk more outbreaks and drug resistance, underscoring the need for new diagnostics, vaccines, and policy action to curb TB at home and worldwide.

West Coast Faces HMPV Surge as No Vaccine Exists

A highly contagious human metapneumovirus (HMPV) is surging on the West Coast, with wastewater data showing elevated levels in Northern California and rising cases nationwide; there is no vaccine or specific treatment, and care is limited to supportive measures. Common symptoms include cough, fever, nasal congestion and shortness of breath, with young children, older adults and the immunocompromised at higher risk of severe illness; prevention focuses on hand hygiene, masking when sick and avoiding close contact.

Broome County Sees Uptick in Shigellosis Infections, Public Health Warns

Broome County’s health department reports a rise in shigellosis, a bacterial stomach illness caused by Shigella, with about 22 cases since August 2025—well above the typical six per year—prompting prevention guidance (handwashing, careful diaper changes, avoiding swallowing pool water, safe food/water practices when traveling, and avoiding sexual contact for at least two weeks after diarrhea ends). Symptoms typically appear 1–2 days after infection and last up to seven days.

Maine confirms first measles case since 2019, triggering exposure notices

Maine's CDC confirms the state's first measles case since 2019 in an adult who had recently traveled to a state with known cases. The individual was infectious Jan. 28–Feb. 5 and may have exposed people at Saint Joseph’s Hospital in Bangor (Jan. 28) and Hill View Mini Barns in Etna (Jan. 28–29); anyone at those locations during those times should monitor for symptoms and seek medical advice if exposed.

Genetics shape who survives infections once thought harmless

Genetics shape who survives infections once thought harmless

A Nature News feature explains that inherited immune-system mutations—and, more recently, autoantibodies against interferons—help determine why some people die from microbes that are usually harmless. Researchers have cataloged hundreds of inborn errors of immunity (IEIs) across many genes, with defects like interferon-γ receptor mutations causing severe mycobacterial disease, and autoantibodies linked to severe COVID-19 and other infections. Some mutations can even confer protection against specific pathogens (e.g., CCR5 against HIV). With incomplete penetrance and epigenetic regulation, IEIs can vary by cell type and over a person’s lifetime, prompting genetic screening and targeted therapies to prevent or treat severe infections.

US Faces Surge in Measles Cases Amid Outbreaks and Holiday Travel

US Faces Surge in Measles Cases Amid Outbreaks and Holiday Travel

Measles cases are at a 25-year high in the US, spreading rapidly and causing concern among health officials. The highly contagious virus can be prevented with the MMR vaccine, which is highly effective. If exposed, those vaccinated or with presumed immunity generally do not need to take action, but unvaccinated individuals should consider vaccination or antibody treatment. Symptoms include fever, cough, and rash, and while there is no specific treatment, supportive care and prevention are key.

Doctors Alert on Rapidly Spreading Infectious Disease in US

Measles cases are rising across the US, with nearly 2,100 cases in 2025, the highest in 25 years. The highly contagious virus spreads through respiratory droplets and surfaces, but vaccination with the MMR vaccine is highly effective in prevention. Experts advise vaccination after exposure and prompt medical consultation if symptoms develop, emphasizing the importance of herd immunity and vaccination to control outbreaks.
