Zika virus continues to spread in many countries and territories around the globe. Because there is no vaccine or medicine for Zika, the virus and its associated health outcomes will remain a significant and enduring public health challenge.
The Danger from Zika
Although many people infected with Zika experience mild or no symptoms, infection during pregnancy can cause serious birth defects. Areas affected by Zika have also reported increased cases of Guillain-Barré syndrome, an uncommon sickness of the nervous system in which a person’s own immune system damages the nerve cells.
Working together to understand the threat
Experts in CDC’s Global Disease Detection (GDD) program around the world continue their work to track and understand Zika virus. CDC and its global partners – which include ministries of health and agriculture, universities, and U.S. government agencies – are conducting various surveillance and research activities around the world to:
- Monitor the spread of Zika virus
- Determine the range of effects of Zika infection during pregnancy
- Identify potential risk factors for severe Zika-related consequences
- Evaluate the different tests available to diagnose Zika infection in the field
Although, at this time, animals other than mosquitoes do not appear to be involved in the spread of Zika virus to humans, CDC’s work will also investigate the ecology between Zika-carrying animals, including mosquitoes and people.
These activities are ongoing with multiple CDC country offices. CDC’s Division of Global Health Protection is also collaborating with the Naval Medical Research Unit-Six in Peru and CDC colleagues from the Division of Vector-Borne Disease in Ft. Collins, Colorado, to conduct ecological studies in Peru, Colombia, and Brazil.
Critical studies moving forward
CDC’s ongoing surveillance and applied research studies will allow a better understanding of Zika infections, how they are spreading, and where they are occurring.
To date, more than 450 pregnant women have been enrolled in ongoing cohort studies in Guatemala and Kenya. More than 1,000 samples from various animals have been collected for the ecological study; all participating countries have received training on new diagnostic tests for Zika; and surveillance activities have led to detection of Zika cases in various countries.
About CDC’s Global Disease Detection program
CDC’s Global Disease Detection program provides critical surveillance and research data as a foundation for a sustainable global protection strategy. The reach of the GDD network helps countries quickly identify and respond to diseases within their region. GDD surveillance systems focused on one or more diseases or syndromes cover more than 109 million people in 10 countries.
In 2017, the GDD program conducted surveillance at more than 288 unique sites, tracking deadly threats like flu, fevers, and antimicrobial resistance. Below is a snapshot of disease syndromes tracked this year by GDD surveillance systems across the globe.Posted on by
Many doctors and other health workers in my country have limited background or training in leadership and management, yet they often find themselves in leadership positions. This was my case when I was appointed Sub-County Medical Officer in February 2014. Starting out was no easy task, considering I was more used to clinical work. Here, Read More >Posted on by
The 16 Days of Activism Against Gender-Based Violence campaign falls every year between the International Day for the Elimination of Violence against Women on November 25th, and Human Rights Day on December 10th. It is a time to raise awareness and galvanize global support and action to end violence against women and girls around the Read More >Posted on by
AEFI Management Kit. Photo credit: Rania Tohme/CDC More than 100,000 children worldwide are born with congenital rubella syndrome (CRS) every year to mothers infected with the rubella virus. Sadly, these children will suffer a lifetime because of birth defects such as blindness, deafness, and heart disease, even though a cost-effective vaccine is widely available to Read More >Posted on by
Charcoal briquettes manufactured from human waste in East Africa (Photo courtesy of Eric Mintz, CDC) We use toilets every day – at home, school, and work – yet 40% of the world’s population does not have this luxury. Clean and safe toilets are more than just a place to use the restroom. They are essential Read More >Posted on by

Precision Public Health: Using Malawi Population-Based Impact Assessment (MPHIA) Data to Reach HIV Epidemic Control in Malawi
The Malawi Population-Based HIV Impact Assessment (MPHIA) is Malawi’s first nationally representative HIV survey that measures national HIV incidence, pediatric HIV prevalence, and viral load suppression. MPHIA has provided detailed information on the current status of the HIV epidemic and the uptake of HIV prevention, care, and treatment services in Malawi. In his remarks during Read More >Posted on by
Vaccines fight diseases and save lives. Think of achievements like smallpox eradication, a polio-free world close at hand, and 2-3 million deaths prevented each year through routine immunizations. Yet despite a safe and effective vaccine against measles and rubella, these deadly viruses continue to steal the health and lives of children all over the world. Read More >Posted on by
Rabies is a fatal disease that kills an estimated 59,000 people each year, almost half of whom are children. The majority of deaths occur in Africa and Asia. All of these deaths are vaccine-preventable with timely administration of post-exposure prophylaxis (PEP), the shots needed to prevent rabies from developing in bite victims. So why is Read More >Posted on by
Participants to the Rapid Response Team Management workshop, Dakar, Senegal, August 7-11 The 2014-2016 Ebola epidemic clearly demonstrated the need for trained scientists who can deploy quickly to confront health threats and ensure global health security. While we often think about the emergency response itself, we typically don’t think about the work that happens behind Read More >Posted on by
