Measles and rubella were common infectious diseases in Egypt during the prevaccine era. Monovalent measles vaccine was introduced in 1977, and measles vaccination coverage increased from <50% to >90% from 1980 to 1999; however, measles outbreaks continued to occur at 2- to 4-year intervals during this period. After the introduction of a second routine dose of measles vaccine as a combined measles-mumps-rubella (MMR) vaccine in 1999 and the implementation of measles immunization campaigns targeting 6- to 16-year-old children during 2000-2003, reported measles cases dramatically decreased by 2003. In 2002, Egypt established a goal to eliminate measles and rubella and to prevent congenital rubella syndrome (CRS) by 2010. Large-scale rubella and measles outbreaks in 2005-2007, however, led to a revision of the plan of action to achieve the 2010 goals. A nation-wide measles-rubella immunization campaign, targeting children, adolescents, and young adults 2-20 years old, was conducted in 2 phases during 2008-2009 and achieved coverage >95%. With the decrease to record low levels of cases of measles and rubella in 2009 and 2010, Egypt should achieve measles and rubella elimination in the near future, but high coverage(>95%) with 2 doses of measles-rubella vaccine needs to be maintained, measles-rubella surveillance strengthened, and CRS surveillance developed.
SUMMARYIntroduction: Egypt adopted a comprehensive strategy to eliminate measles and rubella by conducting a catch up campaign (in 2008) targeting children and young adults in the age group 10-19 years. This study aimed to explore the seroprevalence of rubella among females aged 20 to 30 years in order to provide the Ministry of Health with information to develop future strategies for rubella supplemental immunization activities among women of childbearing age before marriage and conception.Methods: A total of 339 females in the age group 20 to 30 were selected. The study group comprised women who attended the central laboratory of the Ministry of Health for checking up before travelling abroad as pre-travel requirements for visa application. The collected serum samples were tested for rubella-specific IgG antibodies.Results: The overall prevalence of rubella antibodies in the study group was 88.2%. Around 5.0% of females, who reported that they had been vaccinated, were susceptible to rubella. Age, history of measles, mumps and rubella (MMR) vaccination and past history of rubella infection were considered factors associated with seropositivity for rubella.Conclusion: The seroprevalence rate of rubella antibodies among our female study group was considered low.
The introduction of PCV13 would be a good value for money from the government perspective. It would represent a high-impact public health intervention for Egypt and respond to the National Immunization Technical Advisory Group (NITAG) resolution on reducing pneumonia burden and overall child mortality. Strengthening surveillance will be critical to generating high-quality national data, improving future economic analyses that support evidence-based decisions for introducing vaccines and public health interventions, and to monitoring their impact.
Background: If exposed to oral poliovirus vaccine (OPV), persons with primary immune deficiency disorders (PID) are at increased risk of paralytic poliomyelitis; and can chronically excrete poliovirus. However, the risk of excretion of vaccine derived poliovirus among immunodeficient persons (iVDPV) is not well characterized. We present summary of data from poliovirus surveillance project among PID patients collected between 2011 and 2014 from 11 Egyptian Governorates. Methods: Stool was tested for polioviruses in suspected or confirmed PID children regardless of whether Acute Flaccid Paralysis (AFP) was present or not. Those excreting poliovirus were followed until three consecutive negative stool samples were obtained. Results: There were 122 patients with suspected or confirmed PID identified; 13/122 (11%) excreted poliovirus; of these, 6 excreted iVDPVs, the remaining 7 excreted Sabin virus. The duration of iVDPV excretion ranged from 1 to 21 months. AFP was detected in 3/6 (50%) of those excreting iVDPVs. All iVDPV excretors had history of receiving OPV. Conclusions: Chronic poliovirus excretion in PID patients is rare, however, poliovirus eradication requires removal of all polioviruses from circulation; and because PID individuals are not necessarily paralyzed they might be missed by current poliovirus surveillance based on detection of AFP. To achieve poliovirus eradication, surveillance for polioviruses among PID patients should be routinely conducted in all countries, and poliovirus antiviral therapy must be made available for those with chronic excretion.
