“Cholera vaccine gives indirect protection to unvaccinated people in communities where a substantial fraction of the population gets the vaccine,” according to a study from the island of Zanzibar in East Africa, published in the Lancet on Tuesday, NPR’s “Shots” blog reports. “The effect is called ‘herd immunity,'” the blog notes. According to “Shots,” “half the people in six rural and urban areas received two doses of oral cholera vaccine,” and “[f]or those who got it, the vaccine was 79 percent protective against the disease” while “their neighbors who didn’t get vaccinated had almost as much protection.”

World Leaders Address Climate Change, Water, Food Security At Events On Sidelines Of U.N. General Assembly
U.N. Secretary-General Ban Ki-moon on Thursday at an event hosted by Qatar on the sidelines of the 67th General Assembly meeting “called again for urgent and concrete action on climate change, as high-level officials gathered at the United Nations to discuss the growing global concern over the impacts of the phenomenon on food and water security,” the U.N. News Centre reports. “Climate change is making weather patterns both extreme and unpredictable, contributing to volatility in global food prices, which means food and nutrition insecurity for the poor and the most vulnerable,” the news service writes, noting Ban “has made food security a top priority through the Zero Hunger Challenge he launched at the U.N. Conference on Sustainable Development (Rio+20), held in Brazil in June” (9/27).
“Almost two years after the deadly disease first appeared in Haiti in the aftermath of the Jan. 12, 2010 earthquake, the story of cholera is one of both success and failure,” columnist Catherine Porter writes in a Toronto Star opinion piece. She says though progress has been made in bringing down the death rate from cholera, educating the population on prevention, and getting people with the disease into treatment more quickly, aid agencies’ funding has “dried up and most have ended their cholera programs.” She continues, “In most instances, the Haitian government has not picked up the work that had been done by departing aid agencies. … For its part, the Haitian government has focused on surveillance and prevention — plastering the city with posters about hand-washing and disinfecting water.”
Sudanese Refugee Camps See Improvement In Water, Food Provisions, But Concerns Remain Over Disease Threats, Overcrowding
“Aid agencies say water and food provision has improved in four camps housing more than 105,000 refugees from Sudan’s Blue Nile State, but flooding, disease and an influx of additional refugees pose new threats,” IRIN reports, noting, “Sudan’s government forces and rebels have been fighting in Blue Nile State since September 2011, sending refugees south.” U.N. Refugee Agency (UNHCR) Emergency Health Coordinator Pilar Bauza “says refugees have suffered respiratory and diarrheal diseases, malaria and malnutrition from poor living conditions and nutrition,” the news service writes. “Health education campaigns, an increase in water provision from 10 to 13 liters per day, and a drop in malnutrition from 40 to 33 percent have improved the health of the refugees, but more needs to be done,” according to IRIN.
International Health Groups Ally To Fight Cholera In Haiti; Officials Emphasize Need For Sanitation Infrastructure
“Unless steps are taken to eliminate cholera from Haiti and the neighboring Dominican Republic, the disease will likely resurge and could even spread to other parts of the Caribbean, international health officials said Wednesday,” CQ HealthBeat reports (Bristol, 1/11). Officials from the Pan-American Health Organization (PAHO), UNICEF and the CDC “said they would join with the Haitian and Dominican governments to develop a plan to eradicate cholera from the island the two countries share by extending clean water and sanitation to stricken areas,” Reuters writes, adding, “The effort faces a daunting financial challenge if it is to meet a goal of reaching at least two-thirds of the Haitian population by 2015, a task that could cost $1.1 billion” (Morgan, 1/12).
The U.S. Army news service reports on a five-day Medical Civil Action Program, or MEDCAP, in Tanzania, during which “Tanzanian medical providers working in partnership with U.S. service members from Combined Joint Task Force-Horn of Africa provided medical care to more than 2,100 Tanzanian women and children.” According to the news service, “The program supported the Tanzanian Health Initiative, a program that seeks to provide a comprehensive approach to health for the Tanzanian people and parallels the U.S. government’s Global Health Initiative.”
“A mentally ill man who bathed in and drank from a contaminated river most likely was the first person to be infected” with cholera in the outbreak that began in Haiti in October 2010, researchers from Partners in Health said in a study published Monday in the American Journal of Tropical Medicine and Hygiene, the Associated Press/Washington Post reports (1/9). “‘This patient’s case is the first in the community’s collective memory to have had symptoms that are recognizable, in retrospect, to be those of cholera,’ according to the study,” CNN’s “The Chart” notes, adding, “There is no lab method to confirm that this was the first patient to start the epidemic, wrote the authors” (Park, 1/9).
“Doctors in Zimbabwe said more than 800 cases of typhoid have been reported in Harare, the capital, in an outbreak of the bacterial disease,” GlobalPost reports (Conway-Smith, 1/29). “Health services director Dr. Prosper Chonzi raised fears of a cholera outbreak given the health conditions that gave birth to typhoid,” Xinhua writes (1/28). Chonzi “said … a clean-up and awareness campaign is underway,” according to GlobalPost (1/29).
In this Huffington Post “Impact” blog post, Karl Hofmann, president and CEO of PSI, outlines 10 “milestones for the global health community” that occurred in 2011. Among the achievements, Hofmann says governments avoided making major cuts to foreign aid budgets despite a global economic downturn; studies supported “treatment as prevention” as an HIV prevention strategy; the number of malaria cases and deaths worldwide continued to decline; research showed a promising vaccine candidate to prevent malaria among children; and more women gained access to long-acting, reversible contraceptives. Hofmann also lists advances in social franchising; maternal health; lesbian, gay, bisexual and transgender rights; pneumonia prevention and treatment; and sanitation, hygiene and access to clean water (12/29).
The Democratic Republic of the Congo (DRC) last week “received $9.1 million … from the United Nations Central Emergency Response Fund (CERF) to fight off cholera, which has affected more than 22,000 people and killed 500 over the past year in the central African country,” the U.N. News Centre reports. “In a news release, the Office for the Coordination of Humanitarian Affairs (OCHA) reported that there has been a spike in cases in recent weeks, with the majority of them occurring in eastern provinces where cholera is endemic,” according to the news service (1/27). UNICEF will receive $4.4 million and the WHO will receive $4.7 million to help fight the spread of the disease, which “has ravaged eight of the country’s 11 provinces since January 2011,” Agence France-Presse writes (1/28).
