The difference between acute and chronic conditions

Learn the difference between acute and chronic conditions.

Health conditions can affect people in very different ways, and understanding those differences can help in making informed choices about care and treatment.

Likewise, when it comes to health insurance, it’s important to understand what type of condition you’re suffering from, so you can understand exactly what you’re covered for and what you’re not.

We generally categorise health conditions as either chronic or acute. If you haven’t come across the terms before, you’re probably wondering what ‘chronic’ and ‘acute’ mean in medical terms.

The answer is that some illnesses or health issues may appear unexpectedly and require immediate attention, while others develop gradually and need to be managed over the long term. 

Each type comes with its own challenges, whether that means focusing on short-term recovery or building strategies for ongoing support and lifestyle adjustments. The difference between chronic and acute conditions helps explain why treatment plans vary so widely—from quick interventions to continuous management approaches designed to improve daily life.

By being aware of how health conditions can differ, and of the difference between chronic and acute conditions, you can be better equipped to understand your options and to seek the right kind of care at the right time.

What is a chronic condition?

When it comes to insurance, the Association of British Insurers (ABI) define a chronic condition as a disease, illness or injury which has one of more of the following characteristics: Footnote [1]

  • it needs ongoing or long-term monitoring through consultations, examinations, check-ups and/or tests
  • it needs ongoing or long-term control or relief of symptoms
  • it requires your rehabilitation or for you to be specially trained to cope with it
  • it continues indefinitely
  • it has no known cure
  • it comes back or is likely to come back

Chronic health condition examples

Common examples of chronic health conditions include:

  • Diabetes, a condition that causes a person’s blood sugar to become too high
  • Coronary heart disease or heart disease, where the heart’s blood supply is blocked or interrupted by a build-up of fatty substances in the coronary 
  • Chronic respiratory conditions, like asthma or chronic obstructive pulmonary disease (COPD), which can cause breathing difficulties
  • Osteoarthritis , which causes joint pain and stiffness
  • Chronic neurological conditions like multiple sclerosis or myasthenia gravis

Mental health disorders such as depression and anxiety can also be chronic, if they require long-term treatment and management.

Is cancer a chronic health condition?

Yes, cancer is generally considered a chronic health condition because it often needs long-term treatment, monitoring, and ongoing management. While some cancers can be treated successfully and may go into remission, others can persist or return, making lifelong follow-up care necessary. Modern advances in medicine have allowed many people with cancer to live longer, sometimes managing the disease as a chronic condition rather than facing it as an immediately life-threatening illness.   Treatments such as chemotherapy, radiation, immunotherapy, and targeted drugs can help control cancer over a long period.

However, we approach cancer differently than other chronic conditions when it comes to health insurance.

Does Aviva Health insurance cover chronic conditions?

Aviva Health insurance doesn’t cover chronic conditions in general, such as arthritis and diabetes. However, Aviva Health insurance does cover cancer as standard.

What is an acute condition?

An acute condition is defined by the ABI as a disease, illness or injury that’s likely to respond quickly to treatment which aims to return you to the state of health you were in immediately before suffering the disease, illness or injury, or which leads to your full recovery. Footnote [1]

Usually this means it’s a health issue that develops suddenly and lasts for a fairly short time, often getting better within days or weeks when treated properly. Acute conditions can range from things like the flu, tonsilitis, or pneumonia to a broken bone, kidney stones, or appendicitis.

Will Aviva health insurance cover acute medical conditions?

Yes, our health insurance covers treatment for short-term illnesses or injuries that respond quickly to treatment. We also cover for cancer diagnosis, treatment and aftercare as standard.
