A child’s death comes as measles cases surge in the United States and France, with most infections reported among people who are unvaccinated or not fully vaccinated.
A child has died of measles in New York State, a rare and alarming development that the US Centres for Disease Control and Prevention says comes amid a wider resurgence of the virus across the country. The CDC said that, by 29 October, the United States had recorded 4,852 confirmed cases this year, including infections among international visitors, with measles once again spreading after being declared eliminated nationally in 2000.
The death is a grim reminder that measles is not a benign childhood illness. Antoine Flahault, an epidemiologist at Paris Cité University and honorary professor at the University of Geneva, told actu.fr that in wealthy countries measles still causes roughly one to three deaths in every 10,000 infections. He said that when a measles death is reported in a country such as the United States or France, it usually signals that the virus is circulating widely in the community.
France has also seen a sharp rise in measles activity. Health insurance body Assurance Maladie says the country has recorded 873 cases in 2025, while Santé publique France reported seven deaths last year. Four of those deaths involved immunocompromised adults who caught measles in 2025, and three were children who later died from delayed complications of earlier infections. The agency also said most cases involved people who were unvaccinated or only partly vaccinated.
Measles spreads with extraordinary ease. According to Assurance Maladie, one infected person can pass the virus to 15 to 20 others. Transmission occurs through respiratory droplets, close contact and contaminated surfaces, and patients can be contagious from five days before the rash appears to five days afterwards. The illness typically begins with fever, fatigue, coughing, a runny nose and conjunctivitis before the characteristic rash develops. Complications arise in about 30% of cases, ranging from ear infections and diarrhoea to pneumonia, eye damage and encephalitis, a serious inflammation of the brain.
Public health officials say vaccination remains the most effective defence. In France, the routine schedule calls for one dose at 12 months and a second between 16 and 18 months. For infants entering childcare early, vaccination can start at nine months, with an additional dose later to complete protection. Assurance Maladie also says that people born from 1980 onwards should generally have received two doses of measles, mumps and rubella vaccine, and that catch-up vaccination is recommended when records are incomplete. After exposure to a case, vaccination may be advised within 72 hours, including for some infants aged six to 11 months.
The wider concern is not only individual risk, but the fragility of population immunity. Santé publique France has linked recent cases to outbreaks in households, schools, healthcare settings and childcare facilities, while noting that nearly two-thirds of 2025 cases were in people without full vaccination. That pattern, experts say, leaves infants too young to be fully vaccinated and people with weakened immune systems especially vulnerable. The New York death, in that light, is not an isolated tragedy but part of a broader warning: once measles returns, it can move fast, and it can kill.
