Epidemiological Assessment of African Swine Fever Spread in the Dominican Republic.

Since African Swine Fever (ASF) was detected in the Dominican Republic in July 2021, it has negatively impacted the country's swine industry. Assessing the epidemiological situation is crucial to helping local authorities and industry stakeholders control the disease. Here, data on 155 reported outbreaks in the Dominican Republic from November 2022 to June 2023 were evaluated.

Diagnostic evaluation for Creutzfeldt-Jakob disease in Massachusetts, 1991-2001.

Background: Surveillance for Creutzfeldt-Jakob disease (CJD) in the United States has become a focus of public health attention due to concerns about disease acquired through exposure to transmissible spongiform encephalopathy in other species. A definitive diagnosis requires neuropathologic examination, yet concerns about the invasiveness of procedures and infection control may be barriers to brain biopsy or autopsy in patients with suspected CJD.

Methods: We reviewed medical records of 50 of the 97 patients identified through the Massachusetts Department of Public Health CJD surveillance system for 1991-2001 and of an additional 21 patients in whom CJD was suspected but later ruled out.
