Select the false statement about trachoma:
a. The causative agent is bacterial.
b. It is the leading cause of infectious blindness in the United States.
c. It is transmitted by unhygienic items, such as flies, fingers, and fomites.
d. Uncomplicated cases can be resolved with antibiotics.
e. Severe cases require surgery.

검증된 단계별 안내

Step 1: Understand the disease trachoma. Trachoma is a chronic infectious eye disease caused by the bacterium Chlamydia trachomatis, which makes statement (a) true.

Step 2: Review the epidemiology of trachoma. It is the leading cause of infectious blindness worldwide, especially in developing countries, but not in the United States, which makes statement (b) suspicious or false.

Step 3: Consider the modes of transmission. Trachoma spreads through contact with eye discharge via flies, fingers, and fomites (contaminated objects), so statement (c) is true.

Step 4: Evaluate treatment options. Uncomplicated trachoma cases can be treated effectively with antibiotics, confirming statement (d) as true.

Step 5: Recognize the management of severe cases. Advanced trachoma can cause eyelid deformities requiring surgical intervention, so statement (e) is true.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Etiology of Trachoma

Trachoma is caused by the bacterium Chlamydia trachomatis, making it a bacterial infection. Understanding the causative agent is essential for diagnosis and treatment, as antibiotics target bacteria specifically.

Epidemiology and Transmission of Trachoma

Trachoma is primarily transmitted through contact with infected secretions via flies, fingers, and fomites, especially in areas with poor hygiene. It is a major cause of infectious blindness worldwide but is rare in developed countries like the United States.

Clinical Management of Trachoma

Uncomplicated trachoma cases can be treated effectively with antibiotics to eliminate infection. However, severe or chronic cases may cause eyelid scarring and require surgical intervention to prevent blindness.
