Title: Module 7 - prevention, treatment and control
Post by: Kombmail on October 04, 2019, 08:30:43 pm

hEY guYS can someone help me please with finding sources on malaria for 'investigate and analyse the wide range of interrelated factors involved in limiting local, regional, and global spread?

Hi there,
As you know there are three different levels to control the spread of disease in a population: Local, Regional and Global.
The control methods listed below aren't just specific to malaria and can be applied for most infectious diseases, however I have used malaria as the main example.

Local

• Creating herd immunity through immunisation - for malaria this could include all the people in the population taking malaria tablets (however
  may not be 100% effective)
• Personal hygiene and safe sex practices - for malaria this can be important as once one person has it, it can be transmitted via direct blood
  contact between people eg. needles, from mother to an unborn child, blood transfusion or organ transplant
• Public health campaigns - this can give the local population more information about the disease (eg. malaria) and how to prevent it ie. using
  mosquito nets, wearing insect repellant or taking malaria tablets

Regional

• Environmental considerations
      eg. clean water supplies - draining stagnant water to prevent it becoming a mosquito breeding ground
            sanitation facilities - if disposal of faeces isn't controlled, it may lead to the contamination of water
            climate - the distribution of vectors are affected by the climate eg. the anopheles mosquito which transmits malaria breed in warm, humid
                            climates
            flooding
• Surveillance - could include monitoring the incidence of the disease and taking action if it rapidly increases - for malaria, they may need to drain swamps / mosquito breeding grounds

Global

• Communication between countries and global health organisations about the prevalence and incidence of the disease
• Quarantine - prevent infected people, or the disease entering a disease free country eg. ensuring a mosquito carrying the malaria plasmodium
  does not enter Australia
• Monitoring the movement of infected individuals

If you have the Atar Notes biology course notes book, prevention, treatment and control is covered really well from page 72 onwards

I hope this information is useful!
Good luck  :D
