Infectious Disease Fundamentals Practice Quiz (9 questions)

Explanation

Infectious disease types are classified according to the pathogen responsible for causing the disease, such as bacteria, viruses, fungi, or parasites. Each type has unique characteristics and modes of causing disease, making this classification essential for diagnosis and treatment.

Explanation

Tuberculosis is primarily transmitted through airborne particles expelled when an infected person coughs or sneezes, making airborne transmission via respiratory droplets its main route.

Explanation

The primary role of immune response components is to recognize and eliminate foreign invaders through targeted mechanisms, which includes both innate and adaptive immunity. Innate immunity offers immediate, non-specific defense, while adaptive immunity provides specific, long-lasting protection. The correct answer emphasizes the overall purpose of immune response components in identifying and destroying pathogens to protect the host.

Explanation

A pathogen is any microorganism that can cause disease, including bacteria, viruses, fungi, or parasites. It is not an immune cell, a vaccine, or an antibiotic.

Explanation

Viruses are non-cellular agents that need to infect a host cell to replicate, unlike bacteria, fungi, or parasites which are cellular organisms.

Explanation

Approximately 75% of emerging infectious diseases have a zoonotic origin, meaning they are transmitted from animals to humans.

Explanation

Candidiasis is caused by the fungi genus Candida, a type of eukaryotic organism.

Explanation

Airborne transmission involves pathogens transmitted through aerosols or droplets that can remain suspended in the air, as seen with diseases like tuberculosis and measles.

Explanation

While the revision sheet classifies pathogens into these groups, the foundational classification was established by microbiologists like Louis Pasteur, though the specific author of this classification in the sheet is not named.
