LOS ANGELES — A promising decrease in new MPX cases in Los Angeles County is probably the result of vaccination efforts, changes in behavior among higher-risk individuals and growing natural immunity for survivors, officials said.
The nation’s most populous county publicly reported just 53 new cases of the disease for the seven-day period that ended Thursday. At the apparent peak of the outbreak, from Aug. 19 to Aug. 25, 313 cases were publicly reported.
A similar trend is evident when looking at cases by episode date — a slower but more accurate process that tracks infections based on when someone first tested positive for MPX or started experiencing symptoms. Using that method, L.A. County peaked at about 288 weekly cases for the seven-day period that ended Aug. 20, compared with 62 weekly cases observed in late September.
