Test: Kinds Of Diseases - Class 9 MCQ

Infectious disease spreads faster. 
Infectious Diseases are disorders that are caused by organisms, usually microscopic in size, such as bacteria, viruses, fungi, or parasites that are passed, directly or indirectly, from one person to another.
 

Yellow fever virus is mainly transmitted through the bite of theyellow fever mosquito Aedes aegypti, but other mostly Aedes mosquitoes such as the tiger mosquito (Aedes albopictus) can also serve as a vectorfor this virus.

Chronic diseases affect the long term health of a person which may results to death sometimes.It further affects other parts of the body.Sometimes a person may be mentally frustrated due to long term health illness.So it is more hazardous than acute diseases.

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.

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.

Some waterborne pathogenic microorganisms spread by water can cause severe, life-threatening diseases.Examples are typhoid fever, cholera and Hepatitis A or E. Other microorganisms induce less dangerous diseases.Often,diarrhoea is the main symptom.

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.

Acute diseases last for a short period of time.
Explanation:

Acute diseases are characterized by a sudden onset and a relatively short duration. They typically resolve within a few days to a few weeks. Here are some key points to understand about acute diseases:
- Acute diseases have a rapid onset, meaning they develop quickly.
- They are usually caused by infection, injury, or exposure to harmful substances.
- 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.
In conclusion, acute diseases are characterized by a sudden onset and short duration. They are typically caused by infection or injury and can vary in severity. Prompt medical attention and rest are important for recovery.

Helicobacter pylori (H. pylori) is a type of bacteria. These germs can enter your body and live in your digestive tract. After many years, they can cause sores, called ulcers, in the lining of your stomach or the upper part of your small intestine. For some people, an infection can lead to stomach cancer.
