Test: Kinds Of Diseases - Question 4

Suzan’s grandfather is suffering from tuberculosis. In which category will you put his disease?

Detailed Solution for Test: Kinds Of Diseases - Question 4

To determine the correct category for Suzan's grandfather's tuberculosis, we need to understand the difference between chronic and acute diseases. Here's a detailed explanation:
Chronic Diseases:
- Chronic diseases are long-lasting conditions that persist over time.
- They often develop slowly and worsen gradually.
- Examples of chronic diseases include diabetes, heart disease, and arthritis.
- Chronic diseases can be managed with proper treatment and lifestyle changes, but they may not be completely curable.
Acute Diseases:
- Acute diseases are characterized by sudden onset and short duration.
- They typically have more severe symptoms.
- Examples of acute diseases include the common cold, influenza, and appendicitis.
- Acute diseases can often be treated with medication and resolve within a relatively short period.
Tuberculosis:
- Tuberculosis (TB) is an infectious disease caused by the bacterium Mycobacterium tuberculosis.
- It primarily affects the lungs but can also affect other parts of the body.
- TB can present in different forms, including latent TB infection (asymptomatic) and active TB disease (symptomatic).
- Active TB disease can be further classified as either chronic or acute.
Applying the information to Suzan's grandfather's case:
- Since the question does not provide any information about the duration or severity of his symptoms, we cannot determine whether his tuberculosis is chronic or acute.
- Therefore, we cannot categorize his disease as chronic or acute based on the given information.
- The correct answer is B: She cannot predict anything from this information.
Test: Kinds Of Diseases - Question 5

Which of the following is not an chronic disease?

Detailed Solution for Test: Kinds Of Diseases - Question 5
Answer:
The correct answer is C: Cold and cough.
Explanation:

  • Elephantiasis: Elephantiasis is a chronic disease caused by the parasitic infection of the lymphatic system. It is characterized by the swelling and thickening of the skin and underlying tissues, typically in the legs and genitals.

  • Tuberculosis: Tuberculosis (TB) is a chronic infectious disease caused by the bacterium Mycobacterium tuberculosis. It primarily affects the lungs but can also affect other parts of the body. TB can be a life-threatening condition if not treated properly.

  • AIDS: Acquired Immunodeficiency Syndrome (AIDS) is a chronic disease caused by the Human Immunodeficiency Virus (HIV). It weakens the immune system, making individuals more susceptible to infections and diseases. AIDS is a serious condition that can lead to death if left untreated.

  • Cold and cough: Cold and cough are acute illnesses caused by viral infections. While they can be recurrent, they are not considered chronic diseases as they typically resolve within a few days or weeks.


Therefore, the correct answer is C: Cold and cough.

Test: Kinds Of Diseases - Question 7

Which of the following is a viral disease?

Detailed Solution for Test: Kinds Of Diseases - Question 7
Rabies is a virus that is usually spread by the bite or scratch of an animal. By the time the symptoms appear, it is generally too late to save the patient.
However, a person who may have been exposed to rabies can usually be treated effectively if they seek help at once.

In the United States, between 1 and 3 people contract rabies each year. From 2008 to 2017, the U.S. saw 23 human cases, eight of which were contracted outside the country. Advances in medicine, awareness, and vaccination programs have reduced the incidence of rabies since the 1970s.

However, globally, it remains a problem, and tens of thousands of deaths result from rabies each year, mostly in rural areas of Southeast Asia and Africa. Over 95 percent of infections are caused by dogs.
Test: Kinds Of Diseases - Question 8

Which of the following is not the mode for the transmission of AIDS?

Detailed Solution for Test: Kinds Of Diseases - Question 8

The mode of transmission refers to how a disease is spread from one person to another. In the case of AIDS, it can be transmitted through various means, but there is one option among the given choices that is not a mode of transmission for AIDS.
Hugging is not a mode of transmission for AIDS. HIV, the virus that causes AIDS, cannot be transmitted through casual contact such as hugging. The virus is primarily transmitted through certain body fluids, specifically:
- Sexual contact: This is the most common mode of transmission for HIV. Unprotected sexual intercourse, including vaginal, anal, and oral sex, with an infected person can lead to the transmission of the virus.
- Through blood transfusions: HIV can be transmitted through contaminated blood or blood products. However, with the implementation of strict screening measures, the risk of transmission through blood transfusions has been greatly reduced in many countries.
- From mother to infant during pregnancy: HIV can be transmitted from an infected mother to her baby during pregnancy, childbirth, or breastfeeding. However, with proper medical interventions, the risk of mother-to-child transmission can be significantly reduced.
In conclusion, hugging is not a mode of transmission for AIDS. It is important to understand the correct modes of transmission to prevent the spread of HIV and protect oneself and others from the virus.

- Common examples of acute diseases include the common cold, flu, and food poisoning.
- The symptoms of acute diseases are often severe and intense.
- Acute diseases generally last for a short period of time, ranging from a few hours to a few weeks.
- Prompt medical treatment and rest are often recommended to manage and recover from acute diseases.
- Unlike chronic diseases, acute diseases do not persist over a long period of time.
- It is important to differentiate acute diseases from chronic diseases, as the management and treatment approaches may differ.
