Measles outbreaks return in the U.S. with complications

Measles outbreaks have returned to the U.S., with 320 cases reported in 16 states this year. This resurgence follows a decline in vaccination rates, raising awareness of the disease's long-term complications, including "immune amnesia" and subacute sclerosing panencephalitis (SSPE). "Immune amnesia" occurs when the measles virus damages immune memory cells, leaving individuals vulnerable to other infections. A study found that measles can destroy a significant portion of the body's antibodies, impairing its ability to fight off various diseases. SSPE is a rare but severe complication that can develop 7 to 10 years after measles infection, leading to brain inflammation and progressive loss of function. Vaccination remains the most effective way to prevent measles and its associated risks.
