1.
In which animal does cholera spread?
Correct Answer
B. Clams
Explanation
Cholera is a bacterial infection that spreads through contaminated water or food. Clams are filter feeders, meaning they filter water to obtain food, and they can accumulate and harbor the cholera bacteria in their tissues. Therefore, consuming raw or undercooked clams can lead to the transmission of cholera to humans.
2.
How does cholera spread?
Correct Answer
A. Water
Explanation
Cholera is primarily spread through contaminated water. The bacteria responsible for cholera, Vibrio cholerae, can survive in water sources such as rivers, lakes, and wells. When a person consumes water or food that has been contaminated with the bacteria, they can become infected with cholera. This is why it is crucial to ensure that drinking water is properly treated and that sanitation practices are followed to prevent the spread of cholera. Sneezing and contact with an infected person can contribute to the spread of other diseases, but they are not the main modes of transmission for cholera. Ingesting the blood of a patient is not a known method of cholera transmission.
3.
When did cholera start?
Correct Answer
C. 1800
Explanation
Cholera is an infectious disease caused by the bacterium Vibrio cholerae. It was first identified in the early 19th century, specifically in the year 1817. Therefore, the answer "1800" is correct as it corresponds to the approximate time when cholera started to be recognized and studied as a distinct disease.
4.
Where did cholera start?
Correct Answer
A. India
Explanation
Cholera is a waterborne disease caused by the bacterium Vibrio cholerae. It is believed to have originated in the Indian subcontinent, specifically in the Ganges River delta in India. Historical records indicate that cholera outbreaks occurred in India as early as the 19th century. The disease then spread to other parts of the world through trade routes and human migration. Therefore, India is considered the place where cholera started.
5.
Which of the below is NOT a syptom of cholera.
Correct Answer
C. Coughing
Explanation
Coughing is not a symptom of cholera. Cholera is a bacterial infection that primarily affects the intestines, causing severe diarrhea and dehydration. Cramps and diarrhea are common symptoms of cholera, as they result from the infection's impact on the digestive system. However, coughing is not associated with cholera, as it primarily affects the respiratory system. Blue blood is also not a symptom of cholera, as the infection does not directly affect the color of the blood.
6.
What do you call countries with reported cholera cases in the last 3-5 years?
Correct Answer
A. Endemic
Explanation
Endemic refers to a disease that is regularly found in a certain population or region. In the context of the question, countries with reported cholera cases in the last 3-5 years can be considered endemic because they have a consistent presence of cholera within their borders. This term distinguishes them from countries that do not have any reported cases or have successfully eradicated the disease.
7.
What is dehydration?
Correct Answer
B. Too little water
Explanation
Dehydration refers to a condition where there is a lack of water in the body. It occurs when the body loses more fluid than it takes in, leading to an imbalance in the body's water levels. This can happen due to various reasons such as excessive sweating, vomiting, diarrhea, or not drinking enough water. When the body is dehydrated, it can cause symptoms like dry mouth, fatigue, dizziness, and decreased urine output. Therefore, the correct answer is "Too little water."
8.
What is the name of the bacteria which causes cholera?
Correct Answer
B. Vibrio
Explanation
The correct answer is Vibrio. Vibrio is the name of the bacteria that causes cholera. Cholera is a highly contagious and potentially life-threatening bacterial infection that affects the intestines. Vibrio cholerae is the specific strain of Vibrio bacteria responsible for causing cholera. It is typically transmitted through contaminated water or food and can lead to severe diarrhea and dehydration if left untreated.
9.
How many cholera epidemics are there so far?
Correct Answer
C. 8
Explanation
The correct answer is 8. This suggests that there have been a total of 8 cholera epidemics so far.
10.
Challenge: What is the current sub-type of cholera bacteria called?
Correct Answer
B. El Tor
Explanation
El Tor is the current sub-type of cholera bacteria. It is a strain of the Vibrio cholerae bacterium that causes cholera. This sub-type was first identified in the 1960s and is responsible for most of the cholera cases worldwide. El Tor is known for its ability to cause mild or asymptomatic infections, which can contribute to the spread of the disease. It has become the dominant strain of cholera globally, replacing the classical strain.
