Should Diseases Be Capitalized? A Comprehensive Guide

The question of whether to capitalize diseases is a common one, causing confusion for writers and editors alike. The short answer is: it depends. There's no single, universally accepted rule, but understanding the nuances will help you make the right choice.

When to Capitalize Diseases

Generally, you should capitalize the names of specific diseases, conditions, and syndromes. This is similar to how you capitalize proper nouns like names of people and places. Think of it as giving a specific disease its own unique identifier.

Here are some examples where capitalization is generally correct:

• Alzheimer's disease: This clearly names a specific disease.
• Parkinson's disease: Another example of a proper noun-like disease name.
• Crohn's disease: Capitalization distinguishes this specific inflammatory bowel disease.
• Down syndrome: Named after the physician who first described it.
• Ehlers-Danlos syndrome: Again, a proper noun referring to a group of inherited disorders.
• COVID-19: This is the official name for the disease caused by the SARS-CoV-2 virus, hence the capitalization.

When Not to Capitalize Diseases

Capitalization isn't always necessary. You generally don't capitalize terms that describe a general category of disease or are used as common adjectives.

Consider these situations where lowercase is appropriate:

• lung cancer: While "cancer" can sometimes be capitalized depending on context (e.g., in the name of a cancer organization), "lung cancer" is generally not.
• heart disease: A general category; not a specific disease.
• infectious diseases: This is a general term describing a class of diseases.
• mental illness: A broad term covering various conditions.
• a viral infection: "Viral infection" is a descriptive term; not a specific disease.

The Case of "Cancer"

The word "cancer" itself presents a unique challenge. While "lung cancer" or "breast cancer" are usually lowercased, some style guides suggest capitalization when referring to the disease in a general sense, especially in titles or headings. However, this is inconsistent and often depends on the specific publication's style guide. Lowercase is generally safer unless a style guide dictates otherwise.

Style Guides and Consistency

Ultimately, consistency is key. Choose a style guide (e.g., APA, Chicago, MLA) and adhere to its rules throughout your writing. If you're writing for a specific publication or organization, follow their style guide. Inconsistency is more jarring than choosing one approach or the other.

Examples of Correct Usage:

• Incorrect: The patient was diagnosed with alzheimer's disease.

• Correct: The patient was diagnosed with Alzheimer's disease.

• Incorrect: She suffers from Lung Cancer.

• Correct: She suffers from lung cancer.

• Incorrect: He has a Viral Infection.

• Correct: He has a viral infection.

Conclusion

The capitalization of diseases is nuanced and depends on context and style guides. By understanding when to capitalize and when not to, you can ensure consistent and accurate medical writing. Remember to prioritize clarity and adhere to a consistent style throughout your work. When in doubt, err on the side of lowercase unless a specific style guide indicates otherwise.
