Character Breakdown

Understanding 結核 (Tuberculosis)

結核 (けっかく) refers specifically to tuberculosis, a contagious infectious disease primarily affecting the lungs. It is a medical term used in formal contexts such as hospitals, health reports, and public health announcements.

Usage and Context

When you hear 結核, it usually relates to medical treatment, prevention, or infection control. It is not used casually but appears in serious conversations about health. For example, doctors might discuss 結核の治療 (tuberculosis treatment) or 結核予防 (tuberculosis prevention).

Common Collocations

  • 結核の治療 (けっかくのちりょう): tuberculosis treatment
  • 結核予防 (けっかくよぼう): tuberculosis prevention
  • 結核検診 (けっかくけんしん): tuberculosis screening

These collocations are common in medical and public health contexts.

Important Notes

結核 is a noun and does not conjugate. It is often paired with verbs like する (to do) in phrases such as 検診をする (to have a screening). Learners should avoid confusing 結核 with other respiratory illnesses; it specifically means tuberculosis, not just any lung disease.
