Communicable Diseases
viruses
spreads
viruses spread by using someone who is already infected. This person interacts with people and can cough and sneeze around them, enabling the virus to spread to them. Viruses also spread through contaminated surfaces, surfaces an infected person has touched such as door handles and table tops
infects
once a virus is in a host's body, it can travel along cells' surfaces until it's proteins start to bind with cells' receptors
reproduces
viruses reproduce by hyjacking and taking over a host cell to create copies of themselves. It involves them attaching themselves to the call, injecting it with their ganetic material and using the cell's resources to assemble new viral particles
can/cant be treated
viruses can be treated in ways such as getting rest, drinking fliuds and through medication in some cases such as paracetemol.
protists
-
spreads
protists can spread in many ways such as through a vector (an organism or molecule that acts as a carrier) such as mosquitos, through contaminated water or food and direct contact with infected individuals and surfaces. They can also spread through airbourne spores from fungal like protists
infects
when a person is bitten by a vector (such as a mosquito) the protist makes it's way into the liver where it infects red blood cells and eventually bursts from the blood cells
can/can't be treated
deseases, such as malaria, that come from protists can be treated using methods such asantimalarial drugs (for malaria) or antiprotozal drugs for other infections. treatment is usually ver strong and difficult as protists are eukaryotes- making them similar to human cells
Fungi
-
Infects
- Spreads microscopic spores that are inhaled into lungs
- Skin contact through cuts
- Direct contact with contaminated surfaces (soil or animal)
Spreads
- Fungal spores released into water
- Spread by contaminated surfaces, people, animals.
Reproduces
- Asexually, through fragmentation, budding or producing mitospores.
- Sexually by producing meiospores
Treatment
- Creams, ointments, shampoos
- Medications, pills, powders
- Antifungals
Bacteria
Infects
- Entering the body through routes such as cuts
- Breathing in droplets
- Ingesting contaminated food or water
- Touching contaminated surfaces and then eyes, nose or mouth
Treatments
- Antibiotics
- Some can't be treated by antibiotics (eg - MRSA
Spreads
- Through direct or indirect contamination
- airborne droplets from coughing or sneezing
- contaminated food or water
- vectors like insects or contaminated animals
Reproduces
- Through and asexual process called binary fission, where a single parent grows, duplicate it's DNA and then divides into two genetically identical daughter cells
-
