Which of the following disease is 100% fatal and mode of transmission is through infected animals?

  1. AIDS

  2. Rabies

  3. Tetanus

  4. Hepatitis-B


Correct Option: B
Explanation:

AIDS is transmitted sexually or through blood transfusion or from mother to fetus.
Tetanus is not transmitted from person to person or from animal to person.
Hepatitis-B is transmitted through blood and infected bodily fluids.
Rabies is a fatal viral disease of mammals, most often transmitted through the bite of a rabid animal.
Therefore, the correct answer is option b.

Which one of the following is an example of zoonosis disease?

  1. Measles

  2. Diptheria

  3. Leprosy

  4. Rabies


Correct Option: D
Explanation:

A zoonotic disease is a disease that is transmitted from animals to humans. They can be caused by viruses, bacteria, parasites and fungi. Measles is a viral disease in humans. Diptheria is caused by bacterium Corynebacterium diptheriae. Leprosy is chronic infection caused by bacteria Mycobacterium leprae.
Rabies is one such zoonotic disease caused by the rabies virus of the genus Lyssavirus.
Thus, the correct answer is option (D), 'Rabies'.

Which of these diseases can spread due to the coughing of the patient?

  1. AIDS, T.B. and hepatitis

  2. T.B., influenza and cholera

  3. T.B. and influenza

  4. T.B. and hepatitis


Correct Option: C
Explanation:

Tuberculosis is a disease caused by the bacterium Mycobacterium tuberculosis. Influenza is caused by Haemophilus influenzae.  The infected person coughs and sneezes. These diseases are transmitted through the air droplets while sneezing and coughing. The causative agent survives in the air droplets and through the air, the disease is transmitted to the other person. 

Thus, the correct answer is option C. 

Symptoms of TB include

  1. Fever

  2. Weight loss

  3. Attacks

  4. Both A and B


Correct Option: D
Explanation:

Early symptoms of active TB can include weight loss, fever, night sweats and loss of appetite. Symptoms may be vague, however, and go unnoticed by the affected person. For some, the disease either goes into remission (halts) or becomes chronic and more debilitating with cough, chest pain and bloody sputum (saliva). 

BCG is vaccine meant for protection against 

  1. Mumps

  2. Tuberculosis

  3. Poliomyelitis

  4. Tetanus


Correct Option: B
Explanation:

Bacillus Calmette–Guérin (BCG) vaccine is a vaccine which is primarily used against tuberculosis. In countries where tuberculosis or leprosy is common, one dose is recommended in healthy babies as close to the time of birth as possible. In areas where tuberculosis is not common, only children at high risk are typically immunized, while suspected cases of tuberculosis are individually tested for and treated.

So, the correct answer is 'Tuberculosis'.

Sign and symptoms of a particular diseases are shown related to tuberculosis?

  1. Evening rise of temperature, coughing and weight loss

  2. Infection is nasal cavity, headache, pain in stomach

  3. Infection in alveoli, chills, fever and cough

  4. Intestinal infection, persistent fever


Correct Option: A

Administering BCG vaccine is a preventive measure against

  1. Tuberculosis 

  2. Typhoid

  3. AIDS

  4. Cholera


Correct Option: A
Explanation:

BCG vaccine stands for Bacillus Calmette-Guerin. It is a vaccine against tuberculosis and for the treatment of some bladder cancers.
So, the correct answer is option A.

Tuberculosis can be prevented through vaccination with

  1. MMR

  2. TAB

  3. ELISA

  4. BCG


Correct Option: D
Explanation:

BCG, or Bacille Calmette-Guerin, is a vaccine for tuberculosis (TB). It is made from weakened tuberculosis bacteria that infect cows, similar to the human form of tuberculosis. The vaccine is 70-80% effective against the most severe forms of TB, such as TB meningitis in children.

So, the correct answer is option D.

Which of the following is/are correct regarding tuberculosis?

  1. It commonly affects the lungs.

  2. Bacteria releases tuberculin toxin.

  3. Patient's sputum contains blood.

  4. All of the above.


Correct Option: D
Explanation:
Tuberculosis, or TB, is an infectious bacterial disease caused by Mycobacterium tuberculosis, which most commonly affects the lungs. It is transmitted from person to person via droplets from the throat and lungs of people with the active respiratory disease. The bacteria release toxins known as tuberculin which destroys the organs it infects. The symptoms of active TB of the lung are coughing, sometimes with sputum or blood, chest pains, weakness, weight loss, fever and night sweats. Tuberculosis is treatable with a six-month course of antibiotics.

Vaccines are available for which of the following disease?

  1. Tuberculosis

  2. Brain tumor

  3. Sickle cell anaemia

  4. Common cold


Correct Option: A
Explanation:

Bacille Calmette-Guerin (BCG) is commonly used against tuberculosis. It is normally given to children as it has been shown to provide very good protection against the disseminated forms of TB in children, including TB meningitis. The other diseases do not have any vaccines yet.

So, the correct answer is option A.
