Immunization

Immunization is aprocess that stimulates the body immune system to defend against attack by a
particular contagious. 
I chose immunization because it affects the children’s health, their parents, siblings
and people that they come in contact with. It is important that children get their immunization because more thanthe child may be exposed to disease that may cause death.  I intend to use this information in my career by counseling my parents on the importance of their children immunization.  I work with families now and it is part of my investigation to ask if children shots are up to date.  If a parent tells me that the child’s shot are not up to date, it is my job to make sure that the child gets their shotsbefore I close out the case.  Now I will
be able to counsel my families on why immunization is important for their child
and the family.  I always knew that immunization were important but never really understand the possible outcomesif the children did not get their immunization. In our text The Developing Person Chapter 5 states that benefits of vaccination ranks among the foremost achievement in modern public health.(Dershewitz, 2002)


I chose to explore children’s immunization on yellow fever in sub-Saharan Africa and tropical South America.  Researching yellow fever I found out that there are three transmission cycles for yellow fever: sylvatic (jungle),intermediate (savannah), and urban. 
The sylvatic(jungle) transmission cycle involves transmission of the virus between nonhuman
primates and mosquito species found in the forest canopy. The virus is
transmitted via mosquitoes from monkeys to humans when the humans encroach into
the jungle during occupational or recreational activities.

In Africa, an intermediate (savannah) cycle involves transmission of YFV from tree
hole-breeding  to humans living or working in jungle border areas. In this cycle, the virus may be transmitted from monkeys to humans or from human to human via these mosquitoes.


The urban transmission cycle involves transmission of the virus between humans and urban
mosquitoes, primarily

In Africa the transmissionin rural West Africa is seasonal, with an elevated risk during the end of the rainy season and the beginning of the dry season (usually July–October). However
it may be episodically transmitted during the dry season in both rural and
densely settled urban areas
.
In South America the risk for infection for is highest during the rainy season (January–May, with a peak incidence in February and March). Given the high level of viremia in humans
and the widespread distribution of many towns and cities are at risk for a
large-scale urban epidemic.

    Making sure that all children have immunization is very important in early care. I agree with you, making sure that children are protected from diseases and virus is one of our responsibilities as caregivers.
