- Science: Communicable Diseases
- About communicable Diseases
- Transmittable/ infectious
- Droplets in the air
- Released through sneezing and coughing
- Physical contact
- Spread through actions such as hugging/ touching somebody with the disease/ pathogen
- Contact with contaminated surfaces
- Droplets in the air
- Caused by pathogens
- Virus
- Bacteria
- Fungi
- Examples of communicable diseases
- Common cold
- Smallpox
- Syphilis
- Flu
- Transmittable/ infectious
- About non-communicable Diseases
- Examples of non-communicable diseases
- Diabetes
- Cancer
- Not infections: can't be directly transmitted from one person to another
- However, they can be caught through parasites or insect carriers
- For example, malaria, Malaria isn't contagious and you can't catch it from physical contact with others that are suffering from it; instead, it is transmitted by insect carriers.
- However, they can be caught through parasites or insect carriers

- How health problems interact
- Underlying health issues
- if somebody already has an underlying health issue then they have a higher chance of catching or developing another disease. This can also impact survival chances
- Lifestyle: bad lifestyle choices can impact health
- Smoking
- Too much alcohol
- Unbalanced diet (can lead to obesity)
- Not enough exercise
- Underlying health issues
- First line of defence
- The skin
- Forms an anti-microbial secretion to protect itself
- Cillia
- Goblet cells make sticky mucus to trap particles and bacteria then the cilia act like a brush and sweep them away
- Stomach acid
- Contains hydrochloric acid which kills the pathogens
- Tears, mucus and saliva
- Contain enzymes which can break down the cell wall of most harmful bacteria
- The skin
- Second line of defence
- Immune system
- Ignaz Semmelweis
- He wasn't believed at the time because his theory went against the one at the time and doctors didn't want to be responsible for deaths.
- Evidence of his work still exists today. Some examples of this include the fact that hygiene and hand washing is much more important and equipment is sterilised.
- Found out that the number of cases of puerperal fever (or child-bed fever) greatly decreased when the doctors washed their hands before treating the patients.
- He made the doctors wash their hands in chlorinated lime and cases decreased by 90%.
