Notes from the Field: Chlorination Strategies for Drinking Water During a Cholera Epidemic - Tanzania, 2016.
Since August 2015, the Ministry of Health, Community Development, Gender, Elderly and Children (MoHCDGEC) of Tanzania has been leading the response to a widespread cholera outbreak. As of June 9, 2016, cholera had affected 23 of 25 regions in Tanzania, with 21,750 cumulative cases and 341 deaths reported (Ally Nyanga, MoHCDGEC Emergency Operations Center, personal communication, June 2016). ⋯ Regions surrounding Lake Victoria, in the north, also reported high case counts, including Mwanza with 9% (Ally Nyanga, MoHCDGEC Emergency Operations Center, personal communication, June 2016). Since the start of the outbreak, MoHCDGEC and the Ministry of Water (MOW) have collaborated with the Tanzania Red Cross Society, United Nations Children's Fund (UNICEF), World Health Organization (WHO), and CDC to enhance the water, sanitation, and hygiene (WASH) response to prevent the further spread of cholera.

Notes from the Field: Mycobacterium chimaera Contamination of Heater-Cooler Devices Used in Cardiac Surgery - United States.
In the spring of 2015, investigators in Switzerland reported a cluster of six patients with invasive infection with Mycobacterium chimaera, a species of nontuberculous mycobacterium ubiquitous in soil and water. The infected patients had undergone open-heart surgery that used contaminated heater-cooler devices during extracorporeal circulation (1). In July 2015, a Pennsylvania hospital also identified a cluster of invasive nontuberculous mycobacterial infections among open-heart surgery patients. ⋯ M. chimaera was described as a distinct species of M. avium complex in 2004 (3). The results of the field investigation prompted notification of approximately 1,300 potentially exposed patients.* Although heater-cooler devices are used to regulate patients' blood temperature during cardiopulmonary bypass through water circuits that are closed, these reports suggest that aerosolized M. chimaera from the devices resulted in the invasive infections (1,2). The Food and Drug Administration (FDA) and CDC have issued alerts regarding the need to follow updated manufacturer's instructions for use of the devices, evaluate the devices for contamination, remain vigilant for new infections, and continue to monitor reports from the United States and overseas (2).

State-Specific Prevalence of Current Cigarette Smoking and Smokeless Tobacco Use Among Adults - United States, 2014.
Tobacco use is the leading cause of preventable disease and death in the United States, resulting in approximately 480,000 premature deaths and more than $300 billion in direct health care expenditures and productivity losses each year (1). In recent years, cigarette smoking prevalence has declined in many states; however, there has been relatively little change in the prevalence of current smokeless tobacco use or concurrent use of cigarettes and smokeless tobacco in most states, and in some states prevalence has increased (2). CDC analyzed data from the 2014 Behavioral Risk Factor Surveillance System (BRFSS) to assess state-specific prevalence estimates of current use of cigarettes, smokeless tobacco, and cigarette and/or smokeless tobacco (any cigarette/smokeless tobacco use) among U. ⋯ By race/ethnicity, non-Hispanic whites had the highest prevalence of any cigarette and/or smokeless tobacco use in eight states, followed by non-Hispanic other races in six states, non-Hispanic blacks in five states, and Hispanics in two states (p<0.05); the remaining states did not differ significantly by race/ethnicity. Evidence-based interventions, such as increasing tobacco prices, implementing comprehensive smoke-free policies, conducting mass media anti-tobacco use campaigns, and promoting accessible smoking cessation assistance, are important to reduce tobacco use and tobacco-related disease and death among U. S. adults, particularly among subpopulations with the highest use prevalence (3).

Update: Interim Guidance for Preconception Counseling and Prevention of Sexual Transmission of Zika Virus for Persons with Possible Zika Virus Exposure - United States, September 2016.
CDC has updated its interim guidance for persons with possible Zika virus exposure who are planning to conceive (1) and interim guidance to prevent transmission of Zika virus through sexual contact (2), now combined into a single document. Guidance for care for pregnant women with possible Zika virus exposure was previously published (3). Possible Zika virus exposure is defined as travel to or residence in an area of active Zika virus transmission (http://www.cdc.gov/zika/geo/index.html), or sex* without a condom† with a partner who traveled to or lived in an area of active transmission. ⋯ Couples with possible Zika virus exposure, who are not pregnant and do not plan to become pregnant, who want to minimize their risk for sexual transmission of Zika virus should use a condom or abstain from sex for the same periods for men and women described above. Women of reproductive age who have had or anticipate future Zika virus exposure who do not want to become pregnant should use the most effective contraceptive method that can be used correctly and consistently. These recommendations will be further updated when additional data become available.
