Jerusalem Study Reveals Measles' Deadly Potential Beyond Fever and Rash
Translated & summarized from Behadrei Haredim by baba
A Jerusalem study published in Clinical Microbiology and Infection reveals measles can be fatal, causing severe pneumonia, bacterial infections, and respiratory failure. Analyzing 786 cases from April-December 2025, researchers found 1.4% of hospitalized patients died, with 91% of severely ill individuals unvaccinated and 84% under five. The findings highlight the critical need for vaccination, especially for young children, to prevent life-threatening complications.

- Jerusalem study shows measles can cause fatal complications like pneumonia and bacterial infections.
- 1.4% of hospitalized measles patients in the study died, with most severely ill being unvaccinated children.
- The research analyzed 786 confirmed measles cases presenting at Jerusalem emergency rooms in 2025.
- Unvaccinated individuals and children under five were disproportionately affected by severe measles outcomes.
- The study stresses the critical importance of measles vaccination for preventing severe illness and death.
A new study conducted in Jerusalem has revealed that measles can lead to severe complications, including pneumonia, life-threatening bacterial infections, respiratory failure, and even death, challenging the perception of it as a mild childhood illness. The research, led by Dr. Oren Gordon from the Pediatric Infectious Disease Unit at Hadassah Medical Center, was published in the journal Clinical Microbiology and Infection.
The study analyzed data from 786 confirmed measles cases that presented at emergency rooms in Jerusalem between April and December 2025. Researchers aimed to identify factors associated with severe complications. The findings indicated significant morbidity among these patients: 83.4% required hospitalization, 6.4% needed intensive care, 0.8% required ECMO (extracorporeal membrane oxygenation), and 1.4% died. These figures pertain to patients who sought emergency care, not all measles infections.
Further analysis of 567 patients revealed that 91% were unvaccinated, and approximately 84% were children under five years old, with a median age of just 2.1 years. A significant finding was the high rate of secondary infections: 28.7% suffered from lobar pneumonia, and 3.5% developed bacterial bloodstream infections. The latter was linked to a considerably higher risk of mortality or the need for ECMO.
Severe dehydration and the need for respiratory support were also associated with increased risks of hospitalization and intensive care. The study underscores that even with advanced medical interventions like ventilators, ICUs, and ECMO machines, measles complications can be fatal, particularly for young, unvaccinated children. The findings re-emphasize the critical importance of vaccination in preventing the disease and protecting children's health.
