All of the following is true about the Herd Immunity for infectious diseases EXCEPT: (AI 2005)
- A.
It refers to group protection beyond what is afforded by protection of immunized individuals
- B.
It is likely to be more for infectious diseases that do not have subclinical phase
- C.
It is affected by the presence and distribution of alterative animal hosts
- D.
In the case of tetanus it does not protect the individual.
Correct Answer
A. It refers to group protection beyond what is afforded by protection of immunized individualsExplanation
Herd immunity refers to the protection of a group or community from a contagious disease when a large percentage of individuals in that group are immune to the disease, either through vaccination or prior infection. It is not solely dependent on the protection of immunized individuals, but rather the collective immunity of the entire group. Therefore, the given answer is incorrect.Rate this question:

Herd immunity is not important in: (JIPMER 1993, AI 1995)
- A.
Tetanus
- B.
Pertussis
- C.
Diphtheria
- D.
All
Correct Answer
A. TetanusExplanation
Herd immunity is not important in tetanus because tetanus is not a communicable disease. It is caused by the bacteria Clostridium tetani, which enters the body through wounds or cuts. It does not spread from person to person, so herd immunity does not play a significant role in preventing the transmission of tetanus.Rate this question:

Maternal antibodies are not protective in: (SGPGI 2002)
- A.
Tetanus
- B.
Pertussis
- C.
Diphtheria
- D.
All
Correct Answer
A. TetanusExplanation
Maternal antibodies are not protective in tetanus because tetanus is caused by the toxin produced by the bacteria Clostridium tetani, rather than by the bacteria itself. Maternal antibodies are only effective against the bacteria, not the toxin. Therefore, even if a mother has antibodies against the bacteria, her baby can still be susceptible to tetanus if exposed to the toxin.Rate this question:

Less than 3 days
Correct Answer
A. 7-14 daysExplanation
The usual incubation period of Pertussis, also known as whooping cough, is 7-14 days. This refers to the time it takes for symptoms to appear after exposure to the bacteria that causes the infection. It is important to note that the incubation period can vary from person to person, and some individuals may develop symptoms earlier or later than the average timeframe.Rate this question:

Checking of sputum for AFB comes under: (AIIMS 1995)
- A.
Primary prevention
- B.
Secondary prevention
- C.
Tertiary prevention
- D.
Quaternary prevention
Correct Answer
A. Primary preventionExplanation
Checking of sputum for AFB is a diagnostic test used to detect tuberculosis (TB) infection. Primary prevention refers to measures taken to prevent the occurrence of a disease or condition. In the case of TB, primary prevention includes interventions such as vaccination, health education, and early detection through screening tests like sputum examination. Therefore, checking of sputum for AFB falls under primary prevention as it helps in identifying individuals with TB infection at an early stage, allowing for prompt treatment and reducing the spread of the disease.Rate this question:

- D.
It is performance and analysis of routine measurement aimed at detecting changes in the environment or health status of population
Correct Answer
A. It is a method of identifying the missing casesExplanation
Sentinel surveillance is a method of identifying the missing cases. This means that it is a system that focuses on specific individuals or groups who are more likely to be affected by a certain disease or condition. By monitoring these individuals or groups, any missing cases can be identified and appropriate actions can be taken.

Correct Answer
A. Epidemic typhusExplanation
The given answer, Epidemic typhus, is correct because it is one of the notifiable diseases that are under surveillance. Notifiable diseases are those that health authorities require to be reported when diagnosed in order to track and monitor their occurrence and spread. Epidemic typhus is a bacterial infection transmitted by body lice and can cause severe illness and outbreaks in crowded and unsanitary conditions.

- D.
In the case of tetanus it does not protect the individual.
Correct Answer
A. It refers to group protection beyond what is afforded by protection of immunized individualsExplanation
Herd immunity refers to the protection of a group or community against infectious diseases, which is achieved when a large portion of the population becomes immune through vaccination or previous infection. This immunity not only protects the immunized individuals but also provides indirect protection to those who are not immune. Therefore, the given statement is incorrect as it suggests that herd immunity does not extend beyond the protection of immunized individuals.Rate this question:

- D.
All
Correct Answer
A. TetanusExplanation
Tetanus is not a communicable disease that can be spread from person to person. It is caused by the bacterium Clostridium tetani, which enters the body through wounds or cuts. Therefore, herd immunity is not important in tetanus because it is not a disease that can be prevented through vaccination or through the immunity of a population.Rate this question:

All
Correct Answer
A. TetanusExplanation
Maternal antibodies are not protective in tetanus because tetanus is caused by the bacteria Clostridium tetani, which produces a toxin that affects the nervous system. Maternal antibodies, which are passed from the mother to the baby during pregnancy, do not provide immunity against this specific bacteria and its toxin. Therefore, the baby is not protected against tetanus through maternal antibodies.Rate this question:

- A.
7-14 days
- B.
3-5 days
- C.
21-25 days
- D.
Less than 3 days
Correct Answer
A. 7-14 daysExplanation
The usual incubation period of Pertussis is 7-14 days. This means that after being exposed to the bacteria that causes Pertussis, it takes an average of 7-14 days for symptoms to develop. This period allows the bacteria to multiply and spread in the body before the characteristic symptoms of Pertussis, such as severe coughing fits, begin to appear. Understanding the incubation period is important for diagnosing and managing the disease, as well as for implementing preventive measures to control its spread.Rate this question:

Isolation is not carried out for Plague. Plague is a highly contagious and potentially deadly infectious disease caused by the bacterium Yersinia pestis. It spreads through the bites of infected fleas which live on small mammals such as rats. Isolation is an important measure to prevent the spread of infectious diseases, but in the case of Plague, it is not effective as the disease is primarily transmitted through vectors rather than direct human-to-human contact.Rate this question:

- A.
Virus not found in scab
- B.
Virus can be grown on chick embryo
- C.
Caused by RNA virus
- D.
Does not cross the placental barrier
Correct Answer
A. Virus not found in scabExplanation
Chickenpox is caused by the varicella-zoster virus (VZV), which is known to be present in the scabs of the skin lesions. Therefore, the statement "Virus not found in scab" is incorrect. The virus can be grown on chick embryo, making the statement "Virus can be grown on chick embryo" true. Chickenpox is caused by a DNA virus, not an RNA virus, so the statement "Caused by RNA virus" is false. Lastly, the virus can cross the placental barrier and cause congenital varicella syndrome, making the statement "Does not cross the placental barrier" false.Rate this question:

- C.
6 days after the appearance of rash
- D.
Till the scab falls
Correct Answer
A. As long as patient has feverExplanation
The correct answer is "As long as patient has fever". This means that the infectivity of chicken pox is seen as long as the patient has a fever. Once the fever subsides, the infectivity decreases. It is important to note that chicken pox is highly contagious and can be spread through respiratory droplets or direct contact with the rash. Therefore, it is crucial to take precautions and avoid contact with infected individuals until they are no longer contagious.Rate this question:

A. PolioExplanation
Polio is the correct answer because subclinical infection refers to an infection that does not cause any noticeable symptoms. Polio is known to cause symptoms such as fever, headache, muscle weakness, and paralysis, making it unlikely to have a subclinical infection. On the other hand, mumps, chickenpox, and hepatitis A can all have subclinical infections where individuals may not display any symptoms but still carry the virus.Rate this question:
