The latest case counts in the Democratic Republic of Congo (DRC) are 6,250 cases and 3,039 deaths, as the outbreak continues. Transmission activity is still mainly in North Kivu province.
According to the World Health Organization (WHO), researchers have started to use anonymized phone data used to track population movements in an effort to predict where outbreak clusters may occur.
Population movements have always been a factor in outbreaks, but they are particularly important in the current epidemic.
"Population movements have always been a factor in outbreaks, but they are particularly important in the current epidemic," Olivier Le Polain, head of epidemiology and analytics for response at the WHO Health Emergencies Programme, told Reuters.
The approach has never been used in an Ebola outbreak before, but officials are struggling to contain or slow the spread of the deadly virus in the fourth month of the outbreak. Because the outbreak area is home to mining operations with transient workers and displaced people, the cell phone data could help predict where help is needed.
Lancaster County coroner confirms second measles death in a child
Yesterday the Lancaster County, Pennsylvania, coroner said he was investigating the death of a child who tested positive for measles. It is not clear if this is a new death in addition to the two announced last week, or if this is the second death from last week.
“Just today, we received a report of another child who died with measles, and we’re in the process of doing an investigation,” Stephen Diamantoni told local news affiliates last night. He explained the death occurred “a few weeks ago.”
“I can’t tell you with certainty this is the death the Department of Health and governor’s office was referring to,” he said. “We just want to cast as wide a net as possible and identify any deaths that may have occurred in individuals who had measles.”
Pennsylvania has 540 measles cases
Last week, the Pennsylvania Department of Health (DOH) announced two deaths in the county, including a newborn whose death has become a flashpoint between Health and Human Services Secretary Robert F. Kennedy Jr. and Gov Josh Shapiro. Shapiro and the DOH announced the death as a measles-associated fatality, but the coroner’s report lists a lacerated spleen as the cause of death, leading to conflicting reports about the role measles played in the newborn's death.
Reuters reports Kennedy asked Erica Schwartz, MD, JD, MPH, the new head of the Centers for Disease Control and Prevention (CDC), to remove the Pennsylvania deaths from the CDC’s online measles tally. The move is very atypical, insiders say, as the CDC’s death count usually follows the state’s data.
Currently, the DOH measles dashboard shows two fatalities, 91 hospitalizations, and 540 cases in the current outbreak. The state has recorded 43 cases alone this week.
Study details deaths, anaphylaxis linked to antibiotic injections
A US Centers for Disease Control and Prevention (CDC)–led investigation identified 12 deaths and other severe adverse events linked to ceftriaxone injections at healthcare facilities in 18 states over 11 months, researchers reported today in Clinical Infectious Diseases.
The investigation, conducted with the Alabama Department of Public Health (ADPH) and other state health departments, began in December 2024 after an Alabama county coroner reported two unexpected deaths immediately following ceftriaxone injection at two separate primary care clinics within a single week.
ADPH also received reports of a third death in a hospitalized patient, along with two non-fatal adverse events, following ceftriaxone injection.
After an initial investigation found no evidence of tampering, safety breaches, or common lot exposure, CDC and ADPH in February 2025 expanded their investigation, issuing a national call for reports of severe adverse events (SAEs) that involved death or cardiopulmonary resuscitation (CPR) within six hours of receiving an injection of ceftriaxone.
Reporting health departments submitted data on product exposure, patient medical history, and clinical presentation to the CDC for analysis.
No evidence of tampering, adulteration
From August 2024 to September 2025, 56 SAEs were reported, of which 31 involved death or CPR and were classified as cases. Among the 31 cases (median age, 67 years), 12 patients died, 19 had CPR successfully administered, 23 had anaphylaxis-type reactions, 21 had previous ceftriaxone exposure, and 24 had cardiac comorbidities.
Respiratory infection was the most common indication (42%) for ceftriaxone use among case-patients. Beta-blockers were the most common medication used (61%).
Product testing showed no evidence of tampering, adulteration, endotoxin, or purity/potency issues. Evaluation of Medicare claims and the National Electronic Injury Surveillance System–Cooperative Adverse Drug Event Surveillance System found that national adverse event trends were stable from 2016 through 2019 and 2020 through 2024.
"The absence of a common source etiology, epidemic peak, explanatory product quality issue, or substantial change in national adverse event occurrence over time suggests that the three initial deaths reported in December 2024 may represent a chance clustering of known, albeit severe, adverse reactions to ceftriaxone," the study authors wrote, adding that the investigation highlights the need for ongoing vigilance for ceftriaxone SAEs.
