1.
Blister-like rash on the surface of the skin and mucous membranes. Blisters on trunk and face first before spreading.
Correct Answer
B. Varicella Zoster Virus (chicken pox)
Explanation
The correct answer is Varicella Zoster Virus (chicken pox). Chickenpox is characterized by a blister-like rash on the surface of the skin and mucous membranes. The blisters typically appear on the trunk and face first before spreading to other parts of the body. This description matches the symptoms of chickenpox, caused by the Varicella Zoster Virus.
2.
Cold sores around the mouth/genital area
Correct Answer
D. Herpes Simplex Virus Type 1/Type 2
Explanation
The correct answer is Herpes Simplex Virus Type 1/Type 2. Cold sores around the mouth and genital area are commonly caused by the Herpes Simplex Virus (HSV) Type 1 and Type 2. HSV-1 is typically associated with oral herpes, causing cold sores or fever blisters around the mouth. HSV-2 is usually associated with genital herpes, causing sores or blisters in the genital area. Both types of HSV are highly contagious and can be transmitted through direct contact with an infected person or through sexual contact.
3.
Papules, pustules, flu-like symptoms, and scars after infection.
Correct Answer
A. Variola Virus (smallpox)
Explanation
The given symptoms of papules, pustules, flu-like symptoms, and scars after infection are characteristic of the Variola virus, which causes smallpox. Measles and German measles do not typically cause pustules or scars, making them incorrect choices. Smallpox is known for its distinct rash of raised bumps (papules) that progress to fluid-filled blisters (pustules), accompanied by flu-like symptoms such as fever, headache, and body aches. After the infection resolves, scarring is a common long-term consequence of smallpox.
4.
High fever for at least three days, cough, coryza (runny nose), conjunctivitis (pink eye), and skin rash. Can lead to pneumonia. (Rubeola)
Correct Answer
C. Measles
Explanation
The given symptoms of high fever for at least three days, cough, coryza (runny nose), conjunctivitis (pink eye), and skin rash are characteristic of measles. Measles is a highly contagious viral infection that can lead to complications such as pneumonia. Poliomyelitis and varicella zoster virus (chickenpox) do not present with the same combination of symptoms, making measles the correct answer.
5.
3 days sick. In pregnant women, babies with defects such as cataracts, heart defects, mental retardation, or miscarriage/still birth. (Rubella)
Correct Answer
A. German Measles
Explanation
German Measles, also known as Rubella, is the correct answer. Rubella is a viral infection that can cause various defects in babies if a pregnant woman contracts the disease. These defects include cataracts, heart defects, mental retardation, or even miscarriage or stillbirth. Measles and Influenza are not specifically associated with these particular defects in babies.
6.
Painful testicular swelling, infertility/sub-fertility.
Correct Answer
C. Mumps
Explanation
Mumps is the correct answer because it is a viral infection that commonly causes painful swelling of the testicles (orchitis) in males. This swelling can lead to infertility or sub-fertility. Measles and rotavirus are not associated with testicular swelling or infertility.
7.
Fever, tiredness, vomiting, neck stiffness, leg and arm pain. Destruction of motor neurons leads to muscle weakness and then acute paralysis.
Correct Answer
A. Poliomyelitis
Explanation
The symptoms described, including fever, tiredness, vomiting, neck stiffness, leg and arm pain, and destruction of motor neurons leading to muscle weakness and acute paralysis, are characteristic of poliomyelitis. This viral infection affects the nervous system, particularly the motor neurons in the spinal cord. The destruction of these neurons results in muscle weakness and paralysis. Measles and varicella zoster virus do not typically cause these specific symptoms or affect the motor neurons in the same way.
8.
Chills, then fever, sore throat, muscle pains, severe headache, coughing, weakness, and general discomfort. Serious cases can lead to pneumonia.
Correct Answer
C. Influenza
Explanation
The given symptoms, such as chills, fever, sore throat, muscle pains, severe headache, coughing, weakness, and general discomfort, are commonly associated with influenza. Influenza is a viral infection that affects the respiratory system and can cause a range of symptoms, from mild to severe. In serious cases, it can lead to complications such as pneumonia. Therefore, based on the symptoms described, the correct answer is influenza.
9.
"Common cold" symptoms
Correct Answer
A. Rhinovirus
Explanation
The correct answer is Rhinovirus. Rhinovirus is a common cause of the common cold. It is a type of virus that infects the upper respiratory system, leading to symptoms such as a runny or stuffy nose, sneezing, sore throat, and cough. Influenza, on the other hand, is a different type of virus that causes the flu, which has similar symptoms but is typically more severe. Hepatitis is a viral infection that affects the liver and does not typically cause symptoms associated with the common cold.
10.
Vomiting, watery diarrhea for 3-8 days, fever and abdominal pain. Can lead to death from dehydration.
Correct Answer
C. Rotavirus
Explanation
Rotavirus is the correct answer because it is a common cause of severe gastroenteritis, characterized by symptoms such as vomiting, watery diarrhea, fever, and abdominal pain. It is highly contagious and primarily affects infants and young children. Rotavirus infection can lead to dehydration, which can be life-threatening if not treated promptly. Therefore, the symptoms described in the question align with those caused by rotavirus.
11.
A- acute, not chronic, appearance of jaundiceB- acute and chronic, death due to complications of cirrhosis, and liver cancerC- Chronic, leads to cirrhosis, can be asymptomatic for 10-12 years
Correct Answer
C. Hepatitis
Explanation
Hepatitis is the correct answer because it is a disease that can have both acute and chronic forms. It can lead to cirrhosis of the liver and can be asymptomatic for a long period of time, typically 10-12 years. Additionally, hepatitis can cause jaundice and can lead to complications such as liver cancer.
