Ohio is now dealing with an outbreak, and the Centers for Disease Control and Prevention (CDC) reports nearly 500 total cases in the US.
Captured on the 5th day of this illness, this photograph depicted a posterior view of the back of a patient with a case of measles, highlighting the characteristic erythematous rash that had manifested, and spread over this region. Note how the rash appeared to be a raised crop of irregularly shaped coalescing spots.

Related to infectious disease and public health policy, there have been reports the entire department of Office of Infectious Disease and HIV/AIDS Policy (OIDP) is going to be laid off. This department is part of the Department of Health and Human Services (HHS) and falls under its massive downsizing and restructuring plan that was announced last week. HHS said it was going to reduce its workforce by laying off 10,000 full-time employees, and when combined with HHS’ other efforts expect to reduce the workforce by 20,000 employees. The restructuring would result in a total downsizing from 82,000 to 62,000 full-time employees.
