Correct Answer
D. Headache

Explanation
Hookworm infection is caused by parasitic worms that live in the small intestine. The worms attach themselves to the intestinal wall and feed on blood, leading to symptoms such as diarrhea, weight loss, and abdominal pain. However, headache is not typically associated with hookworm infection. Headaches are more commonly seen in other infections or conditions, so it is not a symptom of hookworm infection.

Hookworm eggs are present in which of the following products in infected persons?
- A.
  
  Sweat
- B.
  
  Faeces
- C.
  
  Urine
- D.
  
  Saliva
Correct Answer
B. Faeces

Explanation
Hookworm eggs are present in the faeces of infected persons. Hookworms are intestinal parasites that primarily live in the small intestine of humans. The adult hookworms lay eggs in the intestines, which are then passed out of the body through the faeces. These eggs can contaminate the soil and survive in favorable conditions. When a person comes into contact with contaminated soil, the hookworm larvae can penetrate the skin and enter the bloodstream, eventually reaching the intestines to mature into adult worms. Therefore, the presence of hookworm eggs in faeces is a key characteristic of the infection.

In severe hookworm infection, which of this is not likely to occur?
- A.
  
  Anaemia
- B.
  
  Protein deficiency
- C.
  
  Emaciation
- D.
  
  Dyspnoea
Correct Answer
D. Dyspnoea

Explanation
Severe hookworm infection can cause various symptoms and complications, including anaemia, protein deficiency, and emaciation. Anaemia occurs because hookworms feed on blood, leading to a decrease in red blood cells and hemoglobin levels. Protein deficiency can occur due to the loss of proteins through the hookworm's feeding process. Emaciation, or extreme weight loss, can result from the parasite's nutrient consumption. However, dyspnoea, or difficulty breathing, is not typically associated with severe hookworm infection.

Which of the following hookworm species can not be transmitted from cat to man?
- A.
  
  Ancylostoma americanus

  Ancylostoma tubaeforme
- D.
  
  Uncinarea stenocyphala
Correct Answer
A. Ancylostoma americanus

Explanation
Ancylostoma americanus is the correct answer because it is a species of hookworm that primarily infects humans, not cats. It is transmitted to humans through the skin, usually when walking barefoot on contaminated soil. Ancylostoma brazillense and Ancylostoma tubaeforme are hookworm species that infect cats and can be transmitted to humans. Uncinarea stenocyphala is another hookworm species that infects cats but does not commonly infect humans.

Explanation
The correct answer is Africa. Hookworm infection is more prevalent in Africa compared to other regions. This can be attributed to various factors such as poor sanitation, lack of access to clean water, and inadequate healthcare infrastructure. These conditions create an environment where hookworms can thrive and easily infect individuals. Additionally, socio-economic factors like poverty and limited education contribute to the higher frequency of hookworm infection in Africa.
