Frequently Asked Questions about the International Health Regulations (IHR)

Why do the International Health Regulations (IHR) matter to me?

A health threat in one part of the world can threaten health anywhere – or everywhere. The International Health Regulations (IHR) are an international agreement focused on addressing serious public health threats that have the potential to spread beyond a country’s borders to other parts of the world. One of the most important aspects of the IHR is the requirement that countries will detect and report events that may constitute a potential Public Health Emergency of International Concern (PHEIC).

Global outbreaks like SARS and Ebola have taught us that an outbreak in one country can easily spread into another. We are all responsible for stopping outbreaks before they become epidemics. The IHR are a framework designed to better protect the world from health threats spreading out of control.

 

How will the IHR protect America’s health?

The IHR define the standards that countries must meet to be able to prevent, detect, and respond to public health threats. The IHR require each country to be able to stop outbreaks of infectious diseases before they spread internationally.

The IHR also seek to create a global network that can rapidly exchange information, as well as global networks to stage a coordinated response in the event of an emergency.

Through the IHR, countries aim to better detect public health threats and report events in their countries to the World Health Organization (WHO). WHO then works collaboratively with those countries and the other member states to effectively respond to the reported event. Ultimately, this helps protect Americans from outbreaks overseas that could come to the U.S.1

Who is in charge of making sure countries reach IHR goals?

The World Health Organization (WHO) is responsible for ensuring that countries comply with the IHR. They are working to:

  • Foster global partnerships
  • Strengthen national disease prevention, surveillance, control and response systems
  • Strengthen public health security in travel and transport
  • Strengthen WHO global alert and response systems
  • Strengthen the management of specific risks
  • Conduct Joint External Evaluations (JEE) to track progress towards reaching the IHR targets

What diseases are notifiable as a potential public health emergency of international concern (PHEIC) under the IHR?

Some diseases always require reporting under the IHR, no matter when or where they occur, while others become notifiable when they represent an unusual risk or situation.

Always Notifiable2:

  • Smallpox
  • Poliomyelitis due to wild-type poliovirus
  • Human influenza (flu) caused by a new subtype
  • Severe Acute Respiratory Syndrome (SARS)

Other Potentially Notifiable Events:

  • Other diseases that might spread quickly through a nation or region. These might include things like cholera, plague, or a viral hemorrhagic fever, like Ebola.
  • Other biological, radiological, or chemical events that meet IHR criteria3
  • Serious illnesses of unknown origin.

How quickly do PHEIC’s have to be reported?

In the U.S., the federal government has the responsibility for assessing and reporting a potential PHEIC concern to WHO. This is done through the WHO regional office for the Americas. U.S. government agencies have 48 hours to make the assessment after learning about an event and an additional 24 hours to notify WHO.4

How many countries have chosen to participate in the IHR?

At present, 196 countries, including all WHO Member States, have chosen to adopt the regulations and to work toward meeting these important public health goals.5

What is the timeline for countries to meet the goals of the IHR?

Countries had agreed to reach the IHR goals by 2016, but many countries have not yet met them. CDC works with countries across the globe to support reaching these goals to protect Americans from public health threats that have the potential to spread internationally.

What is CDC doing to help countries meet the goals of the IHR?

CDC assumes a lead role in IHR implementation as it relates to human disease. Our main focus is on helping countries build the capability to prevent infectious disease outbreaks when possible, detect them rapidly when they occur, and respond effectively to ensure that they do not spread internationally.

One major role for CDC is to support existing health monitoring systems that identify and report diseases. We collaborate with public health authorities in countries to improve the ability of national health monitoring systems to report possible PHEICs under IHR provisions.6

How are the IHR related to the Global Health Security Agenda?

In 2014, most countries had not met the requirements of the IHR, and it was clear that progress toward IHR needed to be accelerated. The United States and a group of like-minded countries launched the Global Health Security Agenda (GHSA).7 The GHSA provides a structure to help countries reach IHR compliance.

The GHSA lays out a framework to:

  • Prevent avoidable epidemics
  • Detect threats early
  • Respond rapidly and effectively8

The GHSA brings much needed attention and resources to global health protection and helps us actualize the IHR by creating clear goals and activities that support the regulations. The GHSA will help us close the gaps left by the IHR – gaps that could leave us vulnerable to disease threats.
