One Health in Action
One Health is an approach that recognizes the interconnectedness of the health of people, animals, and the environment. It involves collaboration across human and animal health, environment, and other relevant sectors. Antibiotic-resistant bacteria have developed the ability to defeat the drugs designed to kill them and are an important One Health issue. Today, advanced molecular detection technologies, such as whole genome sequencing (WGS), allow scientists to study how antibiotic resistance evolves and spreads. WGS also provides important information for responding to disease outbreaks. In a 2015–2018 outbreak of multidrug-resistant Salmonella Heidelberg, WGS revealed that the outbreak in people was connected to contact with dairy calves and calf environments.
In 2015, China – which has the second highest rate of human rabies deaths in the world – pledged to meet the World Health Organization’s (WHO) goal to reach zero human deaths from canine rabies by 2030. To achieve this goal, China’s Center for Disease Control (China CDC) and the US CDC China office and headquarters staff jointly hosted a Stepwise Approach to Rabies Elimination (SARE) Workshop in Beijing in March 2019.
Uzbekistan, a country in Central Asia and part of the former Soviet Union, faces challenges in controlling and preventing zoonotic diseases, which can spread between people and animals. Health risks like brucellosis, which occurs in high numbers in both people and livestock in the region, exist due to inadequate health and veterinary systems, and limited laboratory and surveillance system capacities in the country. The government of Uzbekistan recognizes the threat posed by zoonotic diseases (as the country sees major economic growth in livestock production) and is working to improve the country’s capacity to prevent, control, detect, and treat them.
One Health is the idea that the health of people is connected to the health of animals and our shared environment. Learn why One Health is important and how, by working together, we can achieve the best health for everyone.
In 2011, when an outbreak of variant virus infections in people was linked to exposure to pigs at agricultural fairs, public health officials quickly recognized the need to support states in using a One Health approach to respond effectively to novel influenza A and other zoonotic disease outbreaks in rural areas.
In Thailand, farmers, local health volunteers, and human and animal health officers are using mobile technology to report zoonotic diseases that pose a serious threat to the health of people and animals.
Between 2000 and 2013, the Zhambyl region of Kazakhstan reported the second highest number of Crimean-Congo hemorrhagic fever (CCHF) illnesses in people, out of all the regions in the country. Although outbreaks of CCHF happen regularly in Kazakhstan, public health officials wanted to understand why this particular region had a higher number of cases.
In late 1997, a disease outbreak began in East Africa. In three months, 90,000 people became sick and almost 500 people died. Many animals in the region also died, causing economic difficulties for the people who relied on these animals for milk, meat, and as a trading commodity.
California scientists and veterinarians found themselves in the middle of a mystery in 2007. Over the span of a year, 11 dead or dying sea otters had been found around Monterey Bay, California.
In early 2010, ducks began to disappear in northern Nigeria. People would later report that they noticed there were fewer ducks in the area, but no one thought it was important at the time.
However, a few months later in May 2010, public health officials learned that hundreds of children had become sick in northern Nigeria
