Hearing Care is Health Care
By Bernice McKenzie BLOG

What’s the Difference Between a Treatment and a Cure?

In everyday conversation, people often use the terms treatment and cure interchangeably—but in healthcare, they mean two very different things.

Treatment: Managing the Disease

A treatment is a method used to manage the symptoms of a disease or slow its progression. It doesn’t necessarily eliminate the root cause. Many treatments are lifelong or ongoing, helping patients maintain quality of life and avoid complications.

Examples of treatment:

  • Hearing aids for tinnitus and hearing loss

  • Insulin for diabetes

  • Blood pressure medications for hypertension

  • Antiretrovirals for HIV

These interventions don’t cure the condition—but they can make it livable.

Think of treatment as management, not elimination.

Cure: The Disease is Gone

A cure means the disease is completely eliminated from the body, and it is not expected to return. No further treatment is needed once someone is cured.

Examples of curable conditions in individuals:

  • Strep throat (cured with antibiotics)

  • Hepatitis C (now curable with modern antiviral therapy)

  • Scurvy (resolved by restoring vitamin C)

  • Certain parasitic infections like giardiasis or pinworms

But How Many Diseases Have True Cures?

That’s where things get complicated.

While many diseases can be cured in individuals, only two diseases have been cured at a global level—meaning they’ve been completely eradicated:

  1. Smallpox – eradicated in 1980 thanks to a global vaccination campaign.

  2. Rinderpest – a viral cattle disease, eradicated in 2011.

These are the only two diseases in history to be officially wiped from the face of the Earth.

Most Diseases Are Treatable—Not Curable

Chronic illnesses like diabetes, Alzheimer’s, tinnitus, hearing loss, arthritis, and asthma have no known cure. But with early detection and consistent treatment, people can lead long, meaningful lives.

In audiology, for example, hearing loss and tinnitus are not curable, but treatment options—such as hearing aids, sound therapy, and counseling—can dramatically improve daily life and mental well-being.

Final Thought

When it comes to health, it’s important to understand this distinction:

Cures eliminate disease.
Treatments help you live well with it.

If you’re managing a chronic condition like hearing loss or tinnitus, seeking professional treatment early can make all the difference.
