What ProPublica Found in the Genetic Code of America’s Measles Outbreaks

Article excerpt

ProPublica conducted a genetic analysis of measles outbreaks across America, examining the viral sequences from infections to trace their origins and spread patterns. By studying the measles virus's genetic code, researchers identified connections between outbreaks in different states and communities, revealing how the disease moved through populations. The investigation provides molecular-level evidence of transmission pathways that public health officials use to understand outbreak dynamics. The findings underscore the importance of genetic sequencing in modern epidemiology, offering insights into how measles continues to circulate despite available vaccines. The project illustrates how genetic tools can illuminate disease spread in ways traditional contact tracing sometimes cannot.
