• The U.S. government has provided doses of an experimental antibody drug developed by Mapp Biopharmaceutical to combat the Ebola outbreak in the Congo. • This decision marks a shift in policy, as the U.S. previously stated the treatment would only be available to high-risk American citizens. • The provision of these doses allows for the drug to be used in clinical trials, accelerating the process of determining its efficacy against the virus.

• As of June 18, 2026, a measles outbreak in the U.S. has reached 2,104 confirmed cases across 41 different jurisdictions. • The CDC has issued a warning that increased summer travel may accelerate the spread of the virus, posing a significant risk to families. • This surge highlights a critical public health challenge as officials urge vaccination and awareness to contain the outbreak.

Move comes after Hegseth made shot optional for military in April and Texas outbreak has sickened nearly 300 peopleThe Pentagon has said that boot camps for all the military services are once again requiring the flu vaccination for all recruits after the defense secretary, Pete Hegseth, made the shot optional for the military at the end of April.The development on Wednesday was confirmed by a Pentagon official to the Associated Press and came amid a growing, weeks-long, flu outbreak at the US air force’s boot camp at Lackland air force base in San Antonio, Texas.

The growing number of infections has alarmed agricultural experts, who warn that a wider outbreak could have serious consequences for the Texas beef industry. Continue reading...

• The U.S. federal government has implemented funding cuts and personnel downsizing within biopreparedness programs dedicated to high-consequence infectious diseases (HCID). • These reductions occur while the U.S. is actively managing threats from Ebola and a Hantavirus cluster associated with cruise ship travel. • Although existing infrastructure and protocols are currently handling these outbreaks, experts warn that diminished resources will leave the nation less prepared for future pandemics.

• Scientists are launching clinical trials for several drugs that showed promise in preliminary studies to combat a widening Ebola outbreak. • The trials are focusing on treatments for the virus currently affecting regions such as the Democratic Republic of Congo, including the town of Mongbwalu. • This effort is critical as health workers struggle to contain the spread of the virus and manage patients suspected of having the Bundibugyo strain.

• A World Health Organization (WHO) expert warned on Friday, June 12, that "blind spots" in the Democratic Republic of Congo may be hiding the true scale of the current Ebola outbreak. • The expert suggests that the spread of the deadly disease could be significantly wider than what is currently reflected in official estimates. • This gap in data is critical because it hinders the ability of health agencies to accurately track and contain the virus's transmission.

• On June 2, 2026, the CDC issued a travel alert for seven Sub-Saharan African countries—Chad, Guinea, Niger, Nigeria, Mali, Mauritania, and Somalia—following a severe diphtheria outbreak. • The alert follows alarming 2025 WHO data documenting 20,412 suspected cases and 1,252 deaths across Africa, highlighting a critical public health crisis. • The warning serves as a vital notice for travelers and unvaccinated Americans to ensure proper immunization before visiting the affected regions.

• Health experts and epidemiologists will monitor U.S. wastewater and social media for disease-causing microorganisms during the upcoming World Cup. • By detecting pathogens in sewage, officials can identify potential outbreaks early and alert medical clinicians to specific symptoms to prevent misdiagnosis. • This proactive surveillance is designed to protect both international soccer fans and the general public from severe illnesses during the high-traffic event.

• British health authorities announced a one-off vaccination programme on Friday, June 12, to protect thousands of students against meningococcal B (MenB) disease. • The initiative follows the largest outbreak of the disease in the UK's history, which occurred earlier this year and notably affected students in Canterbury, Kent. • This urgent public health response aims to curb the spread of the bacteria and prevent further severe cases of meningitis among high-risk student populations.

• In May 2026, outbreaks of Bundibugyo virus disease (BVD) were reported in Uganda and the Ituri province of the Democratic Republic of the Congo. • A transmission model was used to project the growth of the outbreak over a three-month period, highlighting the risk of rapid escalation. • The situation is critical because there are currently no approved vaccines or medications available to treat the *Orthoebolavirus bundibugyoense* species.

Outbreak driven by falling vaccination and misinformation as federal public health cuts hamper state responseThe US has recorded more than 2,000 confirmed measles cases so far this year – near the total of 2,228 recorded in all of 2025, and on track to become the worst year for measles in decades as states struggle with the loss of federal funding for public health.The virus continues to spread in unvaccinated and under-vaccinated communities, including among babies too young to be vaccinated, and it reveals the depths of the twin crises of misinformation and public health in the US.
