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
