what increases probability of catching a communicable disease?
overcrowding, culture and infrastructure, scio-economic factors like lack of trained health workers, poor nutrition, compromised immune system, poor waste disposal, poor swage systems
1 of 8
examples of direct transmission in animals?
kissing body fluids direct skin to skin contact micro organisms from faeces break in the skin animal bite uncture wound or sharing needles contaminated food or water
2 of 8
example of indirect transmission in animals?
socks, athletes foot, veruccas, warts. Cosmetics, cold sorces sharing lipstick. Beeding, gas gangrene. saliva and mucus expelled from talking coughing, influenza tuberculosis
3 of 8
examples of vectors transmit from one host to another in animals?
mosquitoes carry malaria. rats and fleas carry bubonic plague (black death)
4 of 8
what increases the probability of a plant catching a communicable disease?
some varieties less resistant more suseptible to disease. poor mineral nutrition reduced resistance of plants. climate change, increase rainfall and wind, animal vectors enter new areas. damp warm cinditions increase the survival and speed of spores
5 of 8
examples of direct transmission in plants?
ring rot, TMV tomato potato blight, black sigatoka
6 of 8
examples of indirect cntamination in plants?
soil contamination, infected plant leaf bacteria, viruses reproductive spores from protoctista or fungi in the soil. these infect the next crop.
7 of 8
examples of vectors that affect plants?
wind can carry spores, water spores swim in surface water and raindrop splashes, animals feeding birds and insects inoclation by afids. humans hands, formities (clothing socks bedding) farming pactices
