1.
Someone with active TB disease of the lungs can spread TB germs by:
Correct Answer
A. Coughing, laughing, or sneezing
Explanation
Someone with active TB disease of the lungs can spread TB germs through respiratory droplets that are released when they cough, laugh, or sneeze. These droplets contain the bacteria that cause TB and can be inhaled by others, leading to the transmission of the disease. Sharing needles can also transmit TB if the needles are contaminated with the bacteria. However, sharing forks and knives or using a public washroom does not pose a significant risk of TB transmission.
2.
A person with latent TB does not have any symptoms and cannot spread the disease.
Correct Answer
A. True
Explanation
A person with latent TB refers to someone who has been infected with the tuberculosis bacteria but does not show any symptoms of the disease. In this stage, the bacteria are dormant and not actively multiplying in the body. As a result, the person is not contagious and cannot spread the disease to others. However, it is important to note that latent TB can progress to active TB if the person's immune system weakens, making it necessary for them to receive treatment to prevent the disease from becoming active.
3.
TB affects only the lungs.
Correct Answer
B. False
Explanation
This statement is false because TB, or tuberculosis, can affect not only the lungs but also other parts of the body such as the kidneys, spine, and brain. It is a bacterial infection caused by Mycobacterium tuberculosis and can spread through the bloodstream to various organs. Therefore, TB is not limited to only the lungs.
4.
People with the active disease...
Correct Answer
B. Are infectious and can spread the disease
Explanation
People with the active disease of tuberculosis (TB) are infectious and can spread the disease to others. This is because active TB means that the bacteria causing the disease are actively multiplying in the body and can be expelled through coughing, sneezing, or talking, thereby infecting others who come into contact with the infected person. It is important for individuals with active TB to seek treatment to prevent further transmission and to manage their symptoms.
5.
What fraction of the world's population has TB?
Correct Answer
A. 1/3
Explanation
One-third of the world's population has TB. This means that out of every three people in the world, one person is affected by TB. TB is a highly contagious and infectious disease caused by bacteria, and it primarily affects the lungs. It is a significant global health issue, and efforts are being made worldwide to prevent, diagnose, and treat TB.
6.
It is estimated that 2-3 Billion people are infected with TB bacteria and 5-15% of them will develop active TB disease in their lifetime.
Correct Answer
A. True
Explanation
The statement is true because it is estimated that 2-3 billion people are infected with TB bacteria. Out of these infected individuals, 5-15% of them will develop active TB disease at some point in their lifetime. This suggests that a significant proportion of people who are infected with TB bacteria will go on to develop the active form of the disease.
7.
The probability of developing TB is higher among people:
Correct Answer
D. All of the above
Explanation
People with diabetes have a higher probability of developing TB because diabetes weakens the immune system, making it harder for the body to fight off infections. Living in developing countries increases the risk of TB due to factors such as overcrowding, poor healthcare infrastructure, and limited access to treatment. AIDS or living with HIV also increases the likelihood of developing TB as HIV weakens the immune system, making individuals more susceptible to TB infection. Therefore, all three factors contribute to a higher probability of developing TB.
8.
According to World Health Organization (WHO), between 2000-2014, approximately 43 million lives were saved through diagnosis and treatment.
Correct Answer
A. True
Explanation
Between 2000-2014, the World Health Organization (WHO) estimates that around 43 million lives were saved through diagnosis and treatment. This suggests that the efforts made by WHO during this period were successful in improving healthcare outcomes and preventing deaths. The statement is supported by the data provided, indicating that it is true.
9.
You cannot get TB germs from:
Correct Answer
D. All of the above
Explanation
TB (Tuberculosis) is caused by a bacterium called Mycobacterium tuberculosis, which primarily affects the lungs. It is transmitted through the air when an infected person coughs, sneezes, or talks. Therefore, none of the mentioned activities (sharing saliva through kissing, smoking or sharing cigarettes, sharing drink containers or eating utensils) can transmit TB germs. TB is not spread through saliva, sharing personal items, or casual contact. The correct answer is "all of the above."
10.
TB is the #1 killer among people with:
Correct Answer
D. HIV or AIDS
Explanation
TB (Tuberculosis) is an infectious disease caused by the bacteria Mycobacterium tuberculosis. It primarily affects the lungs but can also target other parts of the body. People with weakened immune systems, such as those with HIV or AIDS, are more susceptible to developing active TB disease. This is because HIV weakens the immune system, making it harder for the body to fight off infections like TB. Therefore, among the given options, people with HIV or AIDS are at the highest risk of developing TB, making it the number one killer among this group.
