We Provide Rapid Response to Disease Outbreaks Around the World

Learn about outbreaks, safety actions, and how HHI responds with care and containment.

Overview of Response to Disease Outbreaks

Disease outbreaks, from Zika and Ebola to cholera and COVID-19, can spread fast and devastate communities. We respond to disease outbreaks by providing medical aid, health supplies, PPE, hygiene kits, training and health education. Our teams work with local partners to support outbreak relief and protect at-risk populations.

Support That Makes a Difference

Heart to Heart International is committed to delivering trusted, compassionate relief in times of disease outbreak, wherever and whenever it’s needed most. Together, we can reduce the spread, support recovery, and help communities heal.

What Is an Outbreak of a Disease?

A disease outbreak is when cases of a contagious disease rise quickly beyond expected levels. It can scale into epidemic or pandemic disease levels if it spreads widely. Examples include the Ebola outbreak in West Africa, the Zika virus in Haiti, and the global spread of COVID-19.

How Do Infectious Diseases Spread?

Infectious diseases spread through various modes of transmission: contact, respiratory droplets, contaminated food/water, insect bites, or environmental exposure. Some pathogens spread more rapidly. Understanding their spread helps shape effective outbreak response strategies.

What to do if you’re at Risk of a Disease Outbreak

  • Create a family preparedness plan with contacts, care options, and isolation space.

  • Keep vaccinations and routine medical checkups up to date.

  • Assemble an emergency kit with medicines, masks, hand sanitizer, and cleaning supplies.

  • Follow health alerts from the CDC or your local health department.

  • Limit contact with sick individuals and practice frequent handwashing.

Disease Outbreak Facts & Safety Tips

  • Most contagious diseases spread through close contact or airborne exposure.

  • During an outbreak, hand-washing and surface cleaning reduce risk.

  • Stay updated via public health alerts and avoid crowded areas if infection spreads.

  • Use protective gear like masks and gloves when advised and follow medical guidance instead of rumors.

Disease Outbreak Preparedness

Being ready for a disease outbreak can save lives. A strong plan includes:

  • Staying informed on threats of disease spread.

  • Having basic medical supplies and hygiene kits.

  • Knowing early symptoms and seeking help promptly.

  • Social distancing and maintaining good hygiene during active disease outbreaks.

  • Supporting community health training and education.

Preparedness not only protects your household, it strengthens community resilience in the face of pandemic disease. For detailed guidance on diseases, visit Ready.gov’s page.

Impact Stories

An epidemic refers to the sudden increase in the number of cases of a disease above what is normally expected in a specific geographic area or population. It is typically localized, such as an outbreak of measles in a single city or region.
A pandemic, on the other hand, is an epidemic that has spread across multiple countries or continents, affecting a large number of people. Pandemics usually involve new viruses or infectious agents to which the global population has little or no immunity, leading to rapid and sustained human-to-human transmission.
For example, the 2014–2016 Ebola outbreak in West Africa was an epidemic, while COVID-19 is classified as a pandemic because it spread worldwide.

There are three main classifications of disease outbreaks:

  • Endemic — A disease that is consistently present in a specific geographic area or population, such as malaria in parts of sub-Saharan Africa.
  • Epidemic — A sudden increase in disease cases in a specific area or population, such as a cholera outbreak after a natural disaster.
  • Pandemic — An epidemic that spreads across countries or continents, impacting a significant portion of the population, such as the 1918 influenza pandemic or COVID-19.

A disease outbreak is identified through epidemiological surveillance, where health authorities track patterns of illness in a population. Key indicators of a potential outbreak include:

  • A sudden spike in reported cases of a specific illness.
  • The appearance of a rare or unusual disease in a community.
  • Geographic clustering of similar symptoms or diagnoses.
  • Laboratory confirmation of the same pathogen in multiple patients.
    Public health agencies like the CDC and WHO use case reports, laboratory data, and real-time monitoring systems to confirm an outbreak and determine its source.

A sudden outbreak of disease, often called an acute outbreak, refers to the rapid emergence of numerous cases of a particular illness within a short time frame. This may be caused by factors such as contaminated food or water, introduction of a new pathogen, or environmental changes that favor the spread of disease.
These outbreaks require immediate investigation and response to contain the spread. For example, a norovirus outbreak on a cruise ship can infect hundreds of people within days if not controlled quickly.
