As we celebrate families on Mother’s Day, May 11, and the International Day of Families, May 15, I am especially proud to work in CDC’s Center for Global Health.  As one of the Center’s  health communication specialists, I have the privilege to write or edit many stories about how CDC’s programs impact the lives of families around the world.  In honor of this season, I’d like to highlight a few of my favorite accounts about brave mothers, determined families, and CDC’s global health programs.

 
 
 
 

Mozambique FELTP fellows evaluate impact of malaria bed net campaign

One thing is to read a protocol, and quite another to write a protocol, do the field work, and see it through to the end" - Geraldo Chambe, FELTP resident

Four Mozambican epidemiologists-in-training spent a month walking up to ten kilometers a day to make sure that one of the most effective malaria control interventions was reaching the poorest Mozambicans. Malaria is the leading cause of death in Mozambique, and insecticide-treated bed nets are one of the key malaria control measures. Since 2007, the U.S. President’s Malaria Initiative (PMI) has supported the Mozambican Ministry of Health and the National Malaria Control Program (NMCP) in efforts to reduce the burden of malaria in the country, not only through distribution of bed nets, but other key components as well: indoor residual spraying, diagnostic testing and treatment with effective antimalarials, and intermittent preventive therapy for pregnant women.

In 2013, with PMI support, the NMCP launched a universal bed net distribution campaign in six districts in Nampula Province, located in the northern region of Mozambique. The goal was to provide access to a bed net to the entire population living in the 250,000 households within the target area. The definition of “universal” varies somewhat by country; in Mozambique it means one bed net for every sleeping space. Mass distribution campaigns meant to achieve universal coverage are ambitious, complex, multi-step activities. They involve visiting all households in the distribution area to perform a census, determining how many bed nets to distribute per household, and organizing the logistics of delivering hundreds of thousands of bed nets to remote areas. It is therefore important to evaluate their performance and determine how successful they were in achieving their goal so that lessons learned can inform planning for the next campaign. And for the NMCP, it is important to document how increased bed net ownership and use made possible by campaigns affect malaria transmission.

April 7 is World Health Day

Categories: child health, infectious disease, malaria, mosquito-borne disease, neglected tropical diseases (NTDs), parasitic diseases

    

April 7 marks World Health Day. This year World Health Day focuses on vector-borne diseases. More than half the world is at risk from vector-borne diseases. What exactly is a vector? A vector is a small organism, like a tick or mosquito, that transmits disease. Malaria, dengue, Chagas Disease and lymphatic filariasis are just four examples of vector-borne infectious diseases.   

Come learn about some of these vector-borne diseases and the work that CDC does to prevent, treat, and control these diseases around the world.

The inquiries and images come from almost every state in the United States, and often with a sense of urgency. Still others arrive from Argentina and Germany, Italy, Japan, China, New Zealand, India—and dozens more countries around the globe. Each time the question for CDC’s parasite identification laboratory, known as DPDx, is the same: What is it?

Alexandre J. da Silva, PhD, CDC DPDx

The diagnostic parasitology experts on CDC’s Division of Parasitic Diseases and Malaria’s DPDx team provide answers.

DPDx is the effective merger of technology, laboratory science, and CDC’s unparalleled expertise in parasite identification and the diseases they cause.

DPDx is a unique online educational resource that includes visual depictions of parasite lifecycles, a reference library of free images of parasites, and guidance on proper laboratory techniques for diagnostic parasitology. But it is much more than a Web site.

The primary role of DPDx is reference diagnosis, wherein CDC laboratory scientists confirm diagnoses or discover that the diagnosis is something altogether different from what was originally thought. In both cases, but especially in the latter cases, DPDx impacts treatment. For example, Babesia microti is one of the parasites that cause the tick-borne disease babesiosis; it can be misidentified as Plasmodium falciparum, which causes malaria. The two diseases require different treatments and on many occasions, the DPDx team has corrected a misdiagnosis, ensuring that the patient is appropriately treated.

The 5 Ways Diseases in Other Countries Can Kill You

The world is smaller and people are more mobile than at any time in history. This makes it easier than ever for what’s happening anywhere on the globe to harm Americans’ health. 
 
Here are five ways diseases in other countries pose a threat:

1) The flu could threaten millions. Even in a mild year for flu, in the United States alone, there are thousands of deaths, hundreds of thousands of hospitalizations, and billions of dollars in productivity losses.
 
In a pandemic, millions of people worldwide could be killed. H7N9 influenza, also known as bird flu, is spreading in China, though fortunately it has not mutated to become an infectious disease outbreak that could threaten the health of people around the world.

2) Antibiotic resistance is on the rise. Antibiotic resistance just might be the most urgent health threat facing us now.

The nightmare strain of bacteria known as CRE, carbapenem-resistant Enterobacteriaceae, arose abroad and was introduced to one state in the United States. Now it’s in at least 44 states. It can resist all or almost all antibiotics, kills many of the people who get it in their blood, and spreads its resistance capabilities to other bacteria.

The World Health Organization estimates multidrug-resistant tuberculosis already has infected a half a. million people across the globe.

CDC Collaborations with the Ministry of Health in Dominican Republic Result in Measurable Public Health Gains

For a relatively small country where CDC established a full-time country office only five years ago, the Dominican Republic is suddenly drawing attention.

It’s easy to see why. The Dominican Republic is a popular vacation destination with 1.4 million Americans visiting each year. The country has a unique relationship with its neighbor, Haiti, the poorest country in the Western Hemisphere, where CDC also supports many programs. 

Earlier this month, Dr. Tom Kenyon, Director of CDC’s Center for Global Health and Dr. Debbi Birx, who leads CDC’s Division of Global HIV/AIDs visited the Dominican Republic to review, with Dominican authorities, CDC programs to protect public health. Kenyon and Birx are the highest level CDC officials to visit the DR since CDC’s country office officially opened in 2009.

Number of U.S. Malaria Cases Highest in 40 Years. Have We Forgotten What It Takes To Prevent It?

Progress can be dangerous.

Thanks to malaria elimination efforts in United States in the 1940s, most people in the U. S. today have never had any direct contact with the disease and most doctors have never seen a case. That success means it’s easy to have a relaxed attitude about protecting ourselves.

We’re now seeing the result of that relaxed attitude – the highest number of malaria cases in the United States in the past 40 years.

That’s the conclusion of our recent analysis that finds there were 1,925 malaria cases reported in the United States in 2011. Sadly, the number also includes five deaths.

CDC Malaria Hotline—When the Caller is Ill Abroad

Since 2007, managing the CDC Malaria Hotline has been a large part of my job as a health educator in the Division of Parasitic Diseases and Malaria at CDC. It’s wonderfully fulfilling because it gives me the opportunity to talk directly with the public to share information that can help them avoid malaria infection when they travel. I can hear the public’s concerns and misconceptions about malaria and work to address them in our educational materials.

On average the Hotline handles 6,000 calls a year from mostly the public and healthcare providers—the vast majority are from within the United States. 

The public’s primary concern is whether malaria occurs in the area they plan to visit and if so, what they can do to protect themselves. Sometimes people who have returned ill from their travel call to ask if their symptoms might be malaria. Fortunately, in the U.S. there are well-qualified healthcare providers, clinics, hospitals, and labs available most everywhere, as well as CDC prevention information I can direct them to. 

Saving Mothers, Giving Life Explores “Mother Waiting Sheds”

Categories: child health, health systems strengthening, malaria, parasitic diseases, women's/maternal health

 

This is the fourth installment in a five-part series about efforts to save the lives of mothers in Africa through an initiative called Saving Mothers, Giving Life. Be sure to read the other four blog posts in this series.
 

Nakaliga Deziranta rests in a “Mother Waiting Shed”

Nakaliga Deziranta rests in a “Mother Waiting Shed”

Saving Mothers, Giving Life (SMGL) is exploring an innovative concept aimed at reducing pre-delivery complications – the “Mother Waiting Shed.” The sheds provide at-risk mothers, particularly those traveling from far-off villages, easier access to comprehensive emergency obstetric and neonatal care – essential for averting maternal death and disability. Four waiting sheds, renovated by SMGL with funding from CDC and other partners, have been established at Kibaale Health Center IV, Kakumiro Health Center IV, Kakindo Health Center IV, and Kagadi Hospital. These sheds are just one piece of the comprehensive SMGL program that CDC supports through core strengths in reproductive/maternal health, health systems strengthening, monitoring and evaluation and human resources for health.

The system works this way: mothers with a previous scar, a history of obstetric complications, transport challenges, or mal-presentation of the baby are advised to come early and wait in the shed nearer to the health facility. When mothers arrive to give birth, those who still need time to progress in labor are transferred to the waiting shed where they are constantly monitored by midwives who assess delivery progress. This sort of “triage” system allows mothers to be in a safe environment during a critical touch-and-go period for them and their babies. 

Nakaliga Deziranta, a 26-year old mother of three from Kasambya village, understands the value of these innovative waiting sheds.  She had always attended her antenatal care appointments at Kibaale Health Center IV. During her first visit in January 2013, she was given a dose of intermittent preventive treatment for malaria, mebendazole, an insecticide treated net, and tetanus toxoid, and, over the course of her visits, she was identified as an at-risk patient and consequently advised to travel to the health center early—at the first signs of labor. Heeding this advice, Nakaliga left home when she first began feeling labor pain, and, upon arrival at the health facility, the midwife on duty examined her and established that she was in the latent phase of labor. She made a decision to keep Nakaliga in the facility’s Mother Waiting Shed, and, after three days of progressive labor, Nakaliga finally gave birth to a healthy baby boy. Nakaliga was extremely happy with the care she received while at the shed and then during delivery and has promised to “tell other women to come in time and wait for their time of delivery from the shed.” In rural Uganda, word of mouth may be SMGL’s greatest ally, and other mothers share Nakaliga’s enthusiasm for the waiting shed concept.

Haiti is Saying Goodbye to Lymphatic Filariasis, In Spite of Earthquake

Valery E. Madsen Beau De Rochars, MD, MPH

Our teams gave a two-medicine dose to Haitians in our capital city, Port-au-Prince—but most people had no water to swallow the pills. How would we overcome the ongoing cholera outbreak and displacement from the 2010 earthquake to finally rid Haiti of the horribly disfiguring and painful disease called lymphatic filariasis

Lymphatic filariasis, sometimes known as elephantiasis, is delivered by mosquitoes infected by young, blood-born parasites. The worms lodge in a person’s lymph nodes, causing fluid to pool in their legs and testicles, forcing them to swell dramatically. 

Humans are the only known host for the parasite in Haiti, which means it’s an ideal infectious disease to eliminate. Once we eliminate it from people, it can’t be brought back by animals carrying the parasite, which is the case for many infectious diseases.
