Possible Airborne Person-to-Person Transmission of Mycobacterium bovis — Nebraska 2014–2015

To prevent human disease caused by M. bovis, all milk and dairy products should be pasteurized and people should avoid consumption of unpasteurized milk or dairy products made from unpasteurized milk. Mycobacterium bovis is a bacterium that typically causes disease in cattle, but can also cause tuberculosis infection in persons who consume unpasteurized milk (or dairy products made from unpasteurized milk) in or imported from countries with affected cattle herds. This article reports findings of a large contact investigation in Nebraska around two Hispanic patients with M. bovis tuberculosis with possible spread to persons who had contact with either of them. The results strengthen evidence for person-to-person transmission of this disease. DNA analysis demonstrated that both patients were infected with a similar strain of M. bovis with a foreign origin. The ongoing incidence of M. bovis TB in people substantiates the need to control bovine tuberculosis globally and to promote pasteurization of all milk and dairy products.

Cluster of Ebola Virus Disease Linked to a Single Funeral — Moyamba District, Sierra Leone, 2014

To maintain Sierra Leone at zero new Ebola infections, community-based surveillance strategies will need to be comprehensive and capable of quickly identifying and responding to high-risk events. A single, traditional funeral for a person infected with Ebola led to a sharp increase in Ebola cases in a rural district in Sierra Leone. Among people who attended the funeral, at least 28 became infected with Ebola and eight died, an extremely high rate of secondary transmission. The District’s comprehensive response likely reduced ongoing transmission. This study highlights the importance of single-source cases and events in amplifying the Ebola epidemic.

Progress toward Measles Elimination — Nepal, 2007–2014
To achieve and maintain measles elimination, additional measures are needed: 1) strengthen routine immunization services to increase coverage with first dose of measles vaccine  (MCV1) and a recently introduced 2nd dose of MCV to greater than or equal to 95 percent in all districts, and 2) enhance sensitivity of measles case-based surveillance by adopting a more sensitive case definition, expanding case-based surveillance sites nationwide, and ensuring timely transport of specimens to the accredited national laboratory. In 2013, Nepal adopted a goal for national measles elimination by 2019. This report updates a previous report and summarizes progress toward measles elimination in Nepal during 2007–2014. During 2007–2014, estimated coverage with the  first MCV dose (MCV1) increased from 81 percent to 88 percent. Approximately 3.9 to 9.7 million children were vaccinated in supplementary immunization activities (SIAs) conducted in 2008 and 2014, respectively. Reported suspected measles incidence declined by 13 percent during 2007–2014, from 54 to 47 cases per million population.

Thyrotoxicosis after Consumption of Dietary Supplements Purchased Through the Internet — Staten Island, New York, 2015

Physicians need to inquire about supplements purchased over the counter and via the internet and keep supplements’ toxicities in mind when treating patients. The key objective of this report is to describe a case of toxic thyrotoxicosis caused by ingestion of a diet supplement purchased on the internet. Dietary supplements are not regulated by the FDA and their contents are not often fully disclosed.
