Swaziland achieved high routine immunization coverage until the late 1990s provided through the existing health service delivery structures including outreach services. Since 2001, a fluctuation in DPT3 coverage has been experienced. The key challenge is how to increase and sustain high routine immunization to acceptable levels. The Reaching Every District (RED) approach and Child Health Days (CHD) were adopted as remedies to improve immunization coverage.

The country has maintained and achieved all polio free certification indicators. A total of 17 Acute Flaccid Paralysis (AFP) cases have been reported in 2010. A Non-Polio AFP rate of 3.8 /100,000 and stool adequacy rate of 100% (Jan-December 2010) has been achieved. All reported cases were classified and discarded as Non Polio AFP. This has been achieved through conducting active surveillance in all the regions, disease surveillance trainings, sensitization of clinicians and community health workers.

Following the acceptance of the National Polio Documentation Report by the Africa Regional Certification Committee in 2005, the country is determined to maintain its commitment and efforts towards the global goal of polio eradication. All Polio Committees (National Certification Committee, National Task Force for laboratory containment and National Polio Expert Committee) are fairly functional and progress towards polio eradication is monitored by these committees periodically.

Measles case based surveillance has been implemented since 1998 and with all measles surveillance indicators have been achieved in 2010. A Non Measles Febrile Rash Illness (NMFRI) of 170.9/100,000 has been achieved in 2010. A total of 759 suspected measles cases were notified with 615 (81%) having lab samples and results available for 100%. Among the cases that were serologically investigated 41(5.4%) were rubella IgM positive and 303 measles IgM positive.

All four regions have notified at least 1 suspected case/100,000 population. The measles incidence was 25.9/100,000 population reflecting high occurrence due to the measles outbreak experienced since November 2009 resulting from low immunity of the population against measles over years.
