Summary Unit 10: Infectious Diseases Notes

Topic 10 :

Infectious Diseases
1. Make that
infections diseases are caused
by pathogens
and are transmissible


d. share the name and
type of pathogen
Kar causes each
of the following diseases :




cholera → Vibrio cholerae BACTERIUM

Plasmodium Plasmodium
falciparum Pannodiven
Malaria caused
by promises malarial ,
→
,


ovale and Mannerheim vivax PROTOCh STS
.




Thberuwirns BACTERIUM
Mycobacterium Mycobacterium
→ tuberculosis and bovis



HW/ AIDS
immunodeficiency VIRUS
virus MV
by
→ caused human :




Explain
3. how cholera , malaria TB and HIV/AIDS are transmitted
,




Transmission
of Chhun
bacterium Vibrio cholerae
by
→ caused



→ water-borne and
food-borne
→
affects areas with limited sanitation


→
affects people who become in contact with contaminated water /
food
→
present
in
faeces↳
if contaminates a water
supply
-




intensifies the spread

→
spreads through poor sanitation


Transmission
of malaria
transmitted inserts
→
through ↳
female Anopheles mosquitoes
↳
feed on human blood to obtain
protein to

develop 98
↳
pathogen transfer
→ transmitted
through blood
transfusion and unsterile needles



→ can be
transferred to
foetus aims the
placenta

, Transmission
of TB
→
through droplets from coughing / sneering
inhaled
pathogen
→




spreads quickly overcrowded conditions
→ in




→
spread through cattle either
from
contaminated meat or
unparhauised milk




Transmission
of HWIALDS
→ a retrovirus


group of
↳ a diseases with the
ability to make DNA
from RMA because
they have

reverse
transcriptase
transmitted
by
→ nor a vector

↳ unwue malaria




virus is unable to survive
→
externally

eouhanje of body fluids
transmitted driver
→
by

ways of transmission
:




↳ sexual intercourse
↳ blood donation

↳ mother to
foetus aims
placenta
↳ mother child breast milk
