“…However, by using all cut-off points -except than 5 U/mL -the prevalence of Pertussis infection was significantly different in terms of gender. In a study among Turkish children (26), IgG titer had no significant correlation with the number of family members, but in another study in Cameroon, (27) significant differences are reported in IgG titer of children according to the number of family members. In our study, we found significant differences in anti-PT IgG levels in cut-points of 40, 50, and 80 U/mL.…”

Background: Pertussis is a highly communicable, vaccine-preventable respiratory disease; which may circulate even in populations with high vaccination coverage. Although frequent, but it is often underestimated as a cause of prolonged cough illness in both children and adults. Without boosting, the protection of the childhood vaccination would be minimal after 10 years. The need for adult booster vaccination depends on the national epidemiology. Objectives: The aim of this study was to evaluate the seroepidemiological incidence of Pertussis in fresh college students in four majors. Patients and Methods: In a cross sectional multicenter study, blood samples were obtained from 1617 junior students of four universities. None had received Pertussis booster vaccine in the preceding 10 years. Serum immunoglobulin G (IgG) antibody for Pertussis toxin antigen was measured. Some social and demographic determinants including age, sex and number of family members were recorded. Results: The mean age of participants was 19.64 ± 2.1 years; positive anti Pertussis toxin IgG levels (by cut point of 94 U/mL) was detected in 31.6%. Positivity rate was associated with sex but not with age or residential area. Conclusions: Pertussis continues to challenge medical and public health professionals. Recent reports of increases in the prevalence and incidence may be because of the limited time of protection of childhood vaccination. Our study can serve as one of the scarce populationbased reports from developing countries. A universal cut point should be determined for diagnosis of seropositivity, and a booster of a cellular vaccine is recommended in adolescence.

“…In a Turkish seroprevalence study, IgG antibodies against pertussis were present only in 1/3 of subjects at the age of 0-73 months, while from 12 to 17 years of age, almost all subjects had anti-PT and anti-FHA antibodies, despite the fact that no second pertussis booster was given [10,17]. Such high seroprevalence rates among adolescents indicate widespread natural contacts with Bordetella pertussis and suggest that the incidence rates of pertussis in Turkey are much higher than that reported in the national surveillance system and, thus, those presented here.…”

Pertussis epidemiology was examined in selected Central and Eastern European countries andTurkey (CEEs) from 1945 to 2005. Epidemiology and immunisation coverage data were collected fromNational Health Departments and Epidemiology Institutes. Pertussis diagnosis was made by the World Health Organization (WHO) clinical criteria, laboratory confirmation and/or epidemiological link, except for Romania (WHO clinical case definition used). In the pre-vaccine era, pertussis incidence (except Turkey) exceeded 200/100,000 (range180-651/100,000), with 60-70% of cases occurring in pre-school children. Until 2007, a second-year booster was givenin Estonia, Lithuania and Turkey, and an additional pre-school booster elsewhere. During 1995-2005, immunisation coverage by the age of 2 years exceeded 80% (range 80-98%) and, excluding Estonia, pertussis incidence was <3/100,000. Age-specific incidence rates rose in 5-14 year olds in Poland, Estonia and the Czech Republic. Incidence rates in children <1 year of age remained unchanged. There were two age distribution patterns. In the Czech Republic and Estonia, 16% of cases occurred in pre-school children and 17% and 22% in children >15 years of age, respectively; in Romania, Turkey and Lithuania, 51%, 71% and 73%, respectively, occurred in pre-school children and <7% in children aged >15 years. Pertussis infection persists, despite high immunisation coverage. Compared with the pre-vaccine era, the age distribution changed differentially in CEEs, with an apparent shift towards older children.

“…The determination of sample size was calculated using the Vaughan's formula as follows [6]: N=PQ/(E/1.96) 2 Where P is the maximum expected attendance rate of pregnant women to antenatal cclinics. Q is 100-P E is the margin of sample error tolerated in percentage (5% being the maximum accepted value).…”

Background: Early antenatal booking leads to early detection and management of abnormalities resulting in a reduction in maternal morbidity and mortality rates. The study sought to determine the frequency of antenatal visits, the gestational age at booking and to audit the provision and examine the utilization of antenatal services provided at Comprehensive Health Centre, Umunya. Methods: A retrospective, cross sectional, descriptive study carried out among women who delivered at comprehensive health center, Umunya from January 2007 to July 2014. A sample size of 323 determined by Vaughan's formula was used. Data was extracted from the patients' records and analysed using SPSS 15. Chi-square tests was used as test of significance at p<0.05. Results: Mean gestational age at booking was (mean±SD), 22.76±8.151 weeks. Approximately, two thirds of the women (66.3%) attended antenatal clinic ≥4 times. The assessment of antenatal care services at the center showed that height and weight measurements were done in 33.7% and 65.9%, respectively. Blood pressure was recorded in 99.7%, while almost all the women (95.6%) had routine iron and folic acid supplementation prescribed. Intermittent malaria prophylaxis was prescribed in 19.5% of the women. Tetanus toxoid immunization was administered in 80.5% of the women. In the examination of the utilization of the services, heamoglobin assessment was recorded in 82% of the women, urinalysis in 292 (90.4%), HIV screening in 99.4%, Syphilis test in 75.5% and Blood group test in 77.7%. Conclusion:The study demonstrates suboptimal provision of services especially with height and weight measurements and prescription of malaria intermittent preventive therapy. It also showed suboptimal utilization of laboratory services.
