what is a disease
a condition where a part of an organism doesnt function properly
what are communicable diseases
diseases that can be spread between individuals
what are non communicable diseases
diseases that cant be transmitted between individuals
what are some examples of non communicable diseases
cancer and heart disease
what could be the other effects of being affected by a disease other than dealing with that current disease
- it could make you more susceptible to other diseases
- as your body may be weakened by the disease and be less able to fight off others
what are pathogens
pathogen such as viruses, fungi, protists and bacteria that cause communicable diseases
what are the pathogens and symptoms for cholera
- the pathogen is a bacterium called vibrio cholerae
- the symptoms are diarrhoea
what are the pathogens and symptoms for tuberculosis
- the pathogen is a bacterium called mycobacterium tuberculosis
- the symptoms are coughing and lung damage
what are the pathogens and symptoms for malaria
- the pathogen is a protist
- the symptoms are damage to red blood cells and to the liver
what are the pathogens and symptoms for stomach ulcers
- the pathogen is a bacterium called heliobacter pylori
- the symptoms are stomach pain, nausea and vomiting
what are the pathogens and symptoms for ebola
- the pathogen is the ebola virus
- the symptom is a haermorrhagic fever (fever with bleeding)
what are the pathogens and symptoms for chalara ash dieback
- the pathogen is a fungus that affects ash tress
- the symptoms are leaf loss and bark lesions
how does cholera spread and how can you reduce or prevent its transmission
- it spreads through contaminated water sources
- you can prevent it by making sure people have clean water supplies
how does tuberculosis spread and how can you reduce or prevent its transmission
- it spreads through the air when infected individuals cough
- you can prevent it by infected people avoiding crowded places, practising good hygiene and sleeping alone
- their house should also be well ventilated
how does malaria spread and how can you reduce or prevent its transmission
- it spreads my mosquitoes acting an animal vectors
- they pass on the protist to humans but dont get the disease themselves
- you can prevent it from using mosquito nets and insect repellent to prevent mosquitoes carrying the pathogen from biting people
how do stomach ulcers spread and how can you reduce or prevent its transmission
- they spread through oral transmission, like swallowing contaminated water or food
- you can prevent them by having clean water supplies and hygienic living conditions
how does ebola spread and how can you reduce or prevent its transmission
- it spreads through bodily fluids
- you can prevent it by isolating infected individuals and sterilising anywhere the virus may be present
how does chalara ash dieback spread and how can you reduce or prevent its transmission
- it spreads by the fungus being carried through the air by the wind
- also spreads when diseased ash tress are moved between areas
- you can prevent it by removing young infected ash tress and replanting with different species
- restricting the movement or import of ash trees
