Acting CDC Chief Delays Publication of Vaccine-Effectiveness Study

The CDC's acting director, Dr. Jay Bhattacharya, reportedly postponed releasing an MMWR study showing that 2025–26 Covid vaccines may reduce severe illness, citing concerns about the observational test-negative design; the move has sparked debate about political interference in vaccine research, though officials say it's routine to review methodology and that publication delays are sometimes necessary to ensure analyses are sound.

Flea-Borne Typhus Reemerges, Hospitalizations Climb in L.A.

LA County is contending with a rising outbreak of flea-borne typhus, with about 220 infections reported in 2025 and roughly 90% of patients hospitalized. The illness is spread by fleas carried by animals like rats and opossums and can cause fever, body aches, and rashes two weeks after exposure. Prevention centers on flea control for pets, yard cleanliness, avoiding stray wildlife, and seeking early antibiotic treatment, which is usually effective.

CDC vaccine-benefit study stalls amid political pressure

A CDC study suggesting the 2025–26 COVID-19 vaccine greatly reduces urgent-care visits and hospitalizations among healthy adults was reportedly blocked from publication by acting CDC director Jay Bhattacharya over methodological concerns, in a move linked by critics to political interference under Health Secretary Kennedy Jr. The dispute highlights tensions between science and politics at federal agencies, with officials calling prepublication review routine and skeptics accusing the administration of undermining public health messaging.

New COVID Cicada Variant Hits 25 States, May Evade Immunity

A new COVID-19 variant, BA.3.2 nicknamed cicada, has been detected in at least 25 U.S. states. First identified in South Africa in 2024, US cases rose starting in September 2025, with detections coming from travelers and wastewater. The CDC says the mutation may help the virus evade antibodies and appears highly transmissible, though symptoms resemble other COVID variants. Robust surveillance will guide vaccine updates and responses.

U.S. TB Cases Climb as Latent Infections Reactivate Post-Pandemic

U.S. TB Cases Climb as Latent Infections Reactivate Post-Pandemic

Tuberculosis, known as the white plague, is rising in the United States after COVID-19 disrupted screening and treatment, with 2024 TB cases topping 10,600—the highest since 2013. Health officials say many infections are latent and undiagnosed, reactivating as screenings resume and international travel/migration rebounds. About 25% of people are infected with TB, but 5%–10% progress to active disease. TB is curable with antibiotics, but incomplete treatment risks drug resistance; higher-risk groups include people born in or traveling to TB-burden countries, those living in crowded conditions, and immunocompromised individuals. Emphasis is on testing and treating latent TB to prevent progression to active disease.

CDC mulls new ICD-10 code to track COVID vaccine injuries

CDC officials are weighing a plan to add a distinct ICD-10 code for COVID-19 vaccine injuries to better identify and study adverse effects, with public comments due by mid-May and the code potentially taking effect in fall 2027 if approved; supporters say it could improve care and research and aid data collection, while others caution that the condition is not yet clearly defined and the issue intersects with politics and potential litigation against manufacturers.

Wastewater signals BA.3.2 COVID-19 variant in 25 states, CDC reports

A new SARS-CoV-2 lineage, BA.3.2, is being tracked in the United States through wastewater and clinical samples, with detections across 25 states including travelers and patients. The variant carries 70–75 spike-protein mutations and has shown immune escape characteristics, potentially increasing infections though not necessarily causing more severe disease. The CDC notes ongoing genomic surveillance is essential as BA.3.2 has two sublineages (BA.3.2.1 and BA.3.2.2) and continues to evolve.

New Omicron Subvariant BA.3.2 Raises Immunity-Evasion Flags, CDC Warns

New Omicron Subvariant BA.3.2 Raises Immunity-Evasion Flags, CDC Warns

CDC is monitoring BA.3.2, an Omicron descendant with spike mutations that may reduce protection from prior infection or vaccination. It has reached 25 U.S. states and 23 countries, with about 0.55% of recent U.S. cases identified in sequencing, though wastewater data show BA.3.2 in 132 samples across 25 states, suggesting wider spread. It’s too early to tell if it increases illness severity, but older adults and immunocompromised individuals appear most at risk. The variant likely emerged in South Africa and has spread internationally, with Europe reporting faster transmission. Genomic surveillance varies by country, so the true spread may be underestimated. Ongoing monitoring and vaccination remains important, particularly to protect vulnerable settings.

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.

CDC warns travelers of dengue risk in 16 countries

The CDC updated a Level 1 travel advisory to warn travelers about dengue in 16 countries, urging precautions like long sleeves, insect repellent and sleeping in screened rooms; dengue can rapidly worsen and cause severe symptoms such as brain bleeding, and there is no vaccine for travelers; most US cases come from international travel, with outbreaks recurring every few years.

New Covid variant BA.3.2 spreads across the U.S., raising vaccine-evasion concerns

A new Covid variant, BA.3.2—descended from Omicron—has begun circulating in the United States, detected in travelers, patients, and wastewater samples across more than 20 states and in wastewater from dozens more, with reports spanning at least 25 states and 23 countries. Early lab data suggest BA.3.2 carries spike mutations that may help it evade antibodies generated by current vaccines, prompting monitoring of vaccine effectiveness and potential updates. While not yet the dominant U.S. variant and there’s no clear evidence it causes more severe disease, experts urge vigilance as the virus continues to mutate.
