George Momanyi, Public Health Nurse, START Consultant
George Momanyi, a public health nurse from Kenya, has twice served as a consultant with CDC’s Strengthening Technical Assistance for Routine Immunization Training (START) project in Uganda. START, funded through a grant from the Bill & Melinda Gates Foundation, provides mentoring and on-the-job training to district-level immunization officers and service providers in areas with high numbers of unimmunized children. START consultants make regular visits to district health officers and service providers, delivering training and reinforcing the application of practical job skills. START’s objective is to build the capacity of program staff and thereby strengthen the overall immunization system.
As a START consultant, George worked in eastern Uganda from July-December 2013, and in northern Uganda from February-June 2014. As he was ending his service on the 2nd START team in June, he sent us this blog about his experience.

Geospatial data have been used in public health since John Snow mapped cholera cases around the Broad Street water pump during the London cholera epidemic of 1854. And, while global positioning system technologies (GPS) are so ubiquitous in the United States that virtually all new smartphones, tablets and cars have this technology embedded, in many areas of the world, health care workers in the field are often without the most basic two-dimensional paper maps.
So what do maps and map literacy have to do with polio? Polio is a crippling and potentially fatal infectious disease. There is no cure, but there are safe and effective vaccines. Therefore, the strategy to eradicate polio is based on preventing infection by immunizing every child to stop transmission of the virus that causes polio, and ultimately make the world polio free. The four pillars of polio eradication all rely on “microplans”— detailed logistical blueprints that guide the planning and implementation of vaccination campaigns, routine immunization outreach, and surveillance for polio cases by providing critical data on the size and location of the target population in a given geographic area. These target population numbers determine the amount of vaccine required, the number of health care workers and supervisors to deliver the vaccine, and the cost of transportation to get the vaccine and health care workers where they need to go.

CAR refugees forced from their homes by rebels
Dr. Els Mathieu, Resident Advisor, CAR- FELTP
The Central African Republic (CAR) is a landlocked country in Central Africa, bordered by Chad in the north, Sudan in the northeast, South Sudan in the east, the Democratic Republic of the Congo and the Republic of the Congo in the south and Cameroon in the west. CAR is one of the world’s least developed nations and has experienced several periods of political instability, as well as deadly attacks and violence by rebels that have forced nearly 1 million people from their homes in search of refuge. With so many civilians fleeing to refugee camps in the capital, Bangui, and the provinces, there is an increased need to strengthen disease surveillance and response.

In 2002, I was in Maracaibo, Venezuela assisting with the investigation of the last measles outbreak in South America when the news arrived: Ministers of health from the region agreed that a synchronized week of vaccination in the hemisphere would help prevent future outbreaks and increase access to immunization for many who would miss this opportunity. The idea of Vaccination Week in the Americas ignited 12 years ago and is now a global initiative: World Immunization Week! Since 2003, more than 465 million people in the Americas have been vaccinated under the framework that emerged from the original idea of Vaccination Week in the Americas (VWA), which takes place the last week in April every year.
Carla Lee, MA, Public Health Advisor, CDC Global Immunization Division
VWA is truly a collaborative effort led by countries and territories of the Pan-American Health Organization (PAHO) to improve equity and access to vaccination for families. VWA activities strengthen the national immunization programs in the Americas by reaching out to families with little access to routine immunization programs. The focus is to find people living in urban peripheries, rural and border areas and in indigenous or other hard-to-reach communities and offer them vaccines.
The work has saved lives.
The Region of the Americas encompasses the entire Western Hemisphere (from Canada in the very north all the way down to the southern tip of South America, and all the countries in between), was certified polio-free in 1994. It interrupted the spread of indigenous measles in 2002 and rubella in 2009. However, globally these viruses are still circulating. A huge global sporting event – the World Cup— takes place in Brazil this summer, attracting millions of travelers from around the world. That adds a new element of risk, increasing the risk of importation of vaccine-preventable diseases into the Americas. In light of the World Cup, VWA will highlight the importance of vaccination to protect the health of the people of the Americas, using slogans like “Vaccination: Your best shot,” and “Go on offense: Get vaccinated!”

Pop quiz: What vaccine-preventable disease, whose name means “little red”, can cause severe birth defects if pregnant women become infected? If you answered rubella, also known as German measles, you are right.
Gavin Grant, MD, CDC Global Immunization Division
Susan Reef, MD, CDC Global Immunization Division
It’s okay if you didn’t know, since rubella is mostly a distant memory in the United States thanks to a comprehensive and effective immunization program that’s been in place for decades.
Sadly that’s not true everywhere.
Each year there are thousands of rubella cases around the world, a number that’s made all the more tragic when there is a safe, effective vaccine. And while the number of cases has fallen, the threat remains. Rubella is spread in the same way as the common cold, through sneezing and coughing. In children rubella is typically a mild disease that may include a rash, fever and sore throat. Adults can get rubella as well—usually they experience symptoms such as rash, headache, pink eye, joint pain and general discomfort.

CDC Director Dr. Tom Frieden
There are three places in the world where wild poliovirus has never stopped killing and disabling children: Afghanistan, Pakistan, and Nigeria.
As with other health threats, polio doesn’t stay neatly within a country’s borders. In the case of Nigeria, polio has spread from there to 25 polio-free countries in the past 10 years.
The Nigerian government recognizes this as a public health threat that can be tackled. Last year they put a national emergency action plan in place to eradicate polio and activated an emergency operations center for the work.
The Nigerian plan includes improving immunization activities, outreach to underserved populations, special approaches in security-compromised areas, outbreak response, and improved routine immunization and disease tracking.
In December I had the chance to visit Nigeria and observe firsthand the progress they’re making.
What I saw was impressive. Here are a few highlights from the trip:

Last year, in observance of World Pneumonia Day, Cynthia Whitney, Branch Chief for Respiratory Diseases in the Division of Bacterial Diseases (DBD) and I co-authored a commentary for the CDC Journal of Emerging Infectious Diseases in which we urged the global community to consider the massive problems of pneumonia and to take a moment to consider what we each could do to help solve the problem of pneumonia claiming far too many children. Indeed 2013 has been a very busy year for all committed in the fight against pneumonia—which is part of an urgent and historic global effort to save lives and improve health for millions of women, newborns, and children outlined in the United Nations Millennium Development Goals (MDG).
Rana Hajjeh, MD, Director, CDC Division of Bacterial Diseases
The National Center for Immunization and Respiratory Diseases’ (NCIRD) DBD leads the agency’s pneumonia activities by engaging in research and promoting best practices that address pneumonia everywhere.
Through DBD staff collaboration with partners here at CDC and globally with health care providers, researchers, policy makers, and the greater public health community, we are seeing progress toward reducing disease and deaths due to pneumonia. DBD works with the Advisory Committee on Immunization Practices (ACIP)—which provides advice and guidance to CDC’s Director regarding vaccine use and related agents for control of vaccine-preventable diseases in the United States—and was front and center during the Committee’s meetings this year. Our scientists’ research helped inform the ACIP recommendation on pneumococcal conjugate vaccine (PCV13) for immunocompromised children aged 6-18 years. PCV13 covers 13 pneumococcal serotypes which cause the majority of pneumococcal infections in young children. DBD’s research demonstrated an 88% decline in PCV13-type pneumococcal disease among children less than five years of age in the United States, and 45-65% decline in other age groups due to herd immunity. This year, we completed studies of PCV effectiveness against invasive pneumococcal disease in South Africa and Uruguay and completed the review of vaccine schedules to guide global policy makers adopting PCV into childhood immunization programs. The findings of this comprehensive analysis support the use of either 3 or 4 dose schedules of PCV, and will be published in the Pediatric Infectious Disease Journal in the next few months. We continue to collaborate with partners to assess the effectiveness of PCV in the United States and select developing countries.

October 24th is World Polio Day, a global health observance for the global polio eradication community to renew its promise of a polio-free world to future generations. World Polio Day is held on the birthday of Dr. Jonas Salk, the man who led the first team to develop a vaccine against polio. The development of the polio vaccine reduced polio worldwide by 99% with only Afghanistan, Nigeria, and Pakistan as the remaining polio endemic countries in 2013. In the spirit of World Polio Day, polio eradication program epidemiologist Wick Warren describes his work over the past year in Nigeria.
‘Every last child’ – this is one of the long-running slogans and ideals of the Global Polio Eradication Initiative (GPEI). The Initiative began in 1988, and while incredible progress has been made, (13 million cases of paralytic polio and more than 500,000 deaths prevented in 25 years), the fact that polio has not yet been eradicated proves that we are still not reaching every last child.

I came to CDC to make a difference.
Samir Sodha, MD, MPH, Doctoral Epidemiologist, CDC Global Immunization Division
I am the team lead of the Routine Immunization Team (RIT) which is part of CDC’s Global Immunization Division. GID is well known for the essential role it plays in eradicating polio and eliminating measles/rubella. The goal, and driving memory, is to replicate the historic eradication of smallpox, an achievement that is among the top-tier events in public health history.
The goal for the Routine Immunization Team is no less lofty and in many respects is equally challenging even if it’s less well known. Our mission is to strengthen immunization programs around the world to ensure that the crucial foundation for preventing disease is maintained and even strengthened.

Dr. Francisco Averhoff, Associate Director for Global Health - Division of Viral Hepatitis
Dr. John Ward, Director, Division of Viral Hepatitis (DVH)
On July 28th, the United States joins countries around the globe to observe the third annual World Hepatitis Day. One of only eight health campaigns recognized by the World Health Organization (WHO), this health observance raises awareness of the silent yet growing epidemic of viral hepatitis worldwide. Each year, 1.4 million persons lose their life to viral hepatitis, similar to the number of deaths from HIV/AIDS (1.5 million), tuberculosis and malaria (1.2 million each).
Deaths from viral hepatitis are caused by one of five hepatitis viruses. Hepatitis A and hepatitis E, which are spread fecal-orally either by person-to-person contact or contaminated food or water, are major causes of acute hepatitis, particularly in areas of the developing world suffering from lack of access to clean water and poor sanitation and hygiene. A report in this week’s Morbidity and Mortality Weekly Report describing an outbreak of hepatitis E in a refugee camp in South Sudan reminds us of this often neglected disease that disproportionately kills expecting mothers in many of the poorest countries of the world (see this week’s MMWR).
