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.
