Study Notes

Health and Disease Overview

Illness occurs when harmful germs invade the body, causing infections and diseases, such as the flu.
Two main types of germs: bacteria (living organisms) and viruses (nonliving entities).

Sources of Germs

Germs can be found in:
- Contaminated food and water
- Airborne particles
- Surfaces we touch
- Saliva of insects like mosquitoes

Parasitic Infections

Parasites also lead to infections, which can cause significant health issues.
Common parasites include:
- Hookworms
- Tapeworms
- Lice
- Mites
- Ticks
- Fleas
Effects of parasitic infections:
- Weakness and paleness from parasitic worms
- Skin itching caused by lice and mites

Non-Infectious Health Issues

Not all health problems stem from infections; other causes include:
- Heart diseases
- Diabetes
Congenital problems: Conditions present at birth, including:
- Blindness
- Deafness
- Underdeveloped limbs
Children with congenital problems may face challenges in learning and might look different.

Immune Response and Allergies

The body has mechanisms to combat foreign invaders, like germs.
In some individuals, the immune system overreacts to normal substances, resulting in allergies, which can manifest as:
- Itching
- Runny nose
- Stomach aches
- Breathing difficulties
Common allergens include:
- Milk
- Nuts
- Seafood
- Wheat
- Pollen
- Insect stings (bees, wasps)
- Pets (cats, dogs)
- Certain plants and medications
