The targeted, selective chemotherapy approach was appropriate in addressing low prevalence infection, effective in reducing prevalence rates and transmission of the disease, and in the present situation, more cost-effective than mass distribution.
Therefore primary prevention strategies must be at the forefront of the regional fight to reduce prevalence rates.
Their contribution has enabled the country to virtually eliminate and/or reduce prevalence rates of the highly infectious but preventable diseases namely: measles, polio, diphtheria, pertussis, smallpox and tetanus.
For example, mathematical models have suggested that dosing frequencies can be reduced to once every 3 months and still reduce prevalence rates in dogs and livestock to less than 1% within 10 15 years (Torgerson, 2003).
1 A key modifiable risk factor for NCDs is overweight and obesity, highlighting the need for policy to reduce prevalence rates of overweight and obesity in order to help reduce the rising levels of NCDs.
The choice of whether to consider these single indicator children as having a health problem is not obvious: excluding them will dramatically reduce prevalence rates as well as sample size, while including them may change the composition of the group by including children with varying levels of severity.
Specifically, manufacturing areas are comparatively exposed to HIV and tuberculosis, so controlling mechanism should be applied to reduce prevalence rate.
5 6 7 8 9 10 Differences between present and previously estimated gains of QALYs can be attributed mainly to the effect of screening on non-aneurysm related mortality and to increased life expectancy, reduced prevalence of aneurysms, higher rate for incidental detection, and a more detailed modelling of the disease process.
Outbreaks reached higher prevalence when groups were larger, but subgrouping reduced prevalence.
For example, prevention efforts focus on upstream interventions to reduce overall prevalence rates while new drug targets are identified to improve individual treatment for those with poorly controlled blood sugar levels.
