Health and Diseases Quiz

Study Notes

Understanding Health and Disease

Health is defined as a state of complete physical, mental, and social well-being, not simply the absence of disease.
Disease refers to disturbances in physiological or psychological processes of the body, characterized by specific symptoms.

Types of Infectious Diseases

Diseases can be infectious or non-infectious. Infectious diseases are caused by pathogens such as bacteria, viruses, fungi, and parasites.

Pathogen

A pathogen is any organism that can cause disease, including bacteria, viruses, fungi, and parasites.

Spread of Specific Diseases

Hepatitis: Primarily spread through direct contact with infected bodily fluids or contaminated food and water.
Malaria: Transmitted by female Anopheles mosquitoes in clean water environments.
Scabies: Spread through close physical contact with an infected person or sharing clothing and bedding.
Tuberculosis (T.B.): Infection spread through respiratory droplets when an infected person coughs or sneezes.
Dengue: Spread by Aedes aegypti mosquitoes, which lay eggs in water-logged areas; symptoms include high fever, severe headaches, and pain behind the eyes.
Dysentery: Spread through contaminated food and water, often resulting in severe diarrhea.
Ringworm: A fungal infection spread through direct contact with affected skin or contaminated surfaces.
Swine Flu: Spreads through respiratory secretions of infected pigs or humans; symptoms include difficulty breathing, sore throat, and body pains.

Symptoms of Dengue

Acute fever and headache.
Severe pain in the eye socket.
Decrease in platelet count, which may lead to internal hemorrhage.

Other Notable Diseases

Common illnesses include diabetes, common cold, asthma, Down's syndrome, and heart disease, each with distinct causes and symptoms.

Definition of Health

Health encompasses complete physical, mental, and social well-being.
It is not just the absence of disease or illness.

Disease Spread Mechanisms

Hepatitis: Transmitted primarily through contaminated food and water or direct contact with infected bodily fluids.
Malaria: Spread by female Anopheles mosquitoes that bite infected individuals and transmit the parasite.
Scabies: Caused by mite infestation, spread through direct skin-to-skin contact with an infected person or shared clothing and bedding.
Tuberculosis (T.B.): Airborne disease, transmitted when an infected person coughs or sneezes, releasing bacteria into the air.
Dengue Fever: Spread by Aedes mosquitoes, which bite during the daytime and transmit the virus from infected humans.
Dysentery: Caused by bacteria or parasites, transmitted through contaminated food or water, or through close personal contact.
Ringworm: A fungal infection spread via direct skin contact with an infected person or animal and contaminated surfaces.
Swine Flu: A type of influenza virus; spread mainly through respiratory droplets from coughs or sneezes and touching contaminated surfaces.

Definition of Pathogen

Pathogen refers to any microorganism or agent that can cause disease, including bacteria, viruses, fungi, and parasites.

Definition of Infectious Diseases

Infectious diseases are disorders caused by organisms such as bacteria, viruses, fungi, or parasites, often spread from person to person or through vectors like water and insects.

Infection Through Sputum

Sputum, which is mucus produced in the respiratory tract, can carry pathogens and facilitate the spread of respiratory diseases when expelled through coughing.
