Question

Which of the following is a communicable disease?
A. Phenylketonuria
B. Cancer
C. Rabies
D. Alkaptonuria

Answer 1

A communicable disease is any disease that passes between people or animals.
People sometimes refer to communicable diseases as “infectious” or “transmissible” diseases.
Pathogens, including bacteria, viruses, fungi, and protists, cause communicable diseases.

Step by step answer: Phenylketonuria - Phenylketonuria (PKU) is an inborn error of metabolism that results in decreased metabolism of the amino acid phenylalanine. Untreated, PKU can lead to intellectual disability, seizures, behavioral problems, and mental disorders. It may also result in a musty smell and lighter skin.
Cancer - Cancer is the uncontrolled growth of abnormal cells in the body. Cancer develops when the body's normal control mechanism stops working. Old cells do not die and instead grow out of control, forming new, abnormal cells. These extra cells may form a mass of tissue, called a tumor.
Rabies - Rabies is a deadly virus spread to people from the saliva of infected animals. The rabies virus is usually transmitted through a bite. Animals are most likely to transmit rabies include bats, coyotes, foxes, stray dogs, raccoons, and skunks, etc.
Alkaptonuria- Alkaptonuria is a rare genetic metabolic disorder characterized by the accumulation of homogentisic acid in the body. Affected individuals lack enough functional levels of an enzyme required to breakdown homogentisic acid. Affected individuals may have dark urine or urine that turns black when exposed to air.
As Rabies is caused by a virus so it is a communicable disease.
So, the correct answer is C, i.e., Rabies

Note: Some examples of the reportable communicable diseases include HIV, hepatitis A, B and C, measles, salmonella, measles, and blood-borne illnesses. The most common forms of spread include fecal-oral, food, sexual intercourse, insect bites, contact with contaminated fomites, droplets, or skin contact.
