RESUMO
The monthly retrospective search for unreported acute flaccid paralysis (AFP) cases conducted as a complementary component of the Spanish AFP surveillance system identified a case of AFP in a child admitted in Spain from Senegal during August 2021. Vaccine-derived poliovirus 2 was identified in the stool in September 2021. We present public health implications and response undertaken within the framework of the National Action Plan for Polio Eradication and the Public Health Emergency of International Concern.

OBJECTIVE: Varicella vaccine was recommended in the Community of Madrid (CM) at 15months of age between November 2006 and December 2013. The objective was to describe the impact of vaccination on the incidence of varicella in the CM during the period 2001-2015. DESIGN: A descriptive study of cases of varicella reported to the Sentinel Physician Network of the CM and the cases recorded in the Minimum Basic Data Set at hospital discharge was carried out. Total incidence of cases and of hospital admissions were calculated, as well as specific incidence by age and sex. RESULTS: The incidence was 94.0% lower between 2012 and 2013 than between 2001 and 2003. Between 2014 and 2015 the incidence was 61.8% higher than between 2012 and 2013. The highest incidence was observed in children aged 0 to 4years except for 2010-2014, which was exceeded by the incidence in children aged 5 to 9. The trend in hospital admissions was also decreasing, with the highest incidence in children aged 0 to 1year, followed by 1-4years. CONCLUSIONS: There has been a significant decrease in the incidence of cases and of hospital admissions by varicella in all age groups after the recommendation to vaccinate at 15months of age, which is compatible with the effectiveness of a dose and its ability to produce immunity group. The withdrawal of this recommendation between 2014 and 2015 has led to an increase in the incidence.

OBJECTIVE: Tuberculosis is a major public health problem and most cases are concentrated in vulnerable populations. The objective was to describe the incidence rates trend in native and foreign population (2009-2018) in Madrid Region. METHODS: Retrospective analysis of cases from the Tuberculosis Regional Registry of cases of Madrid Region 2009-2018. Annual incidence rates were calculated by country of birth (Spain, other), sex and age group (<15, 15-34, 35-44, 45-64, >64), using the annual January 1st continuous register population. The infection rate trend and the annual percentage change (APC) were calculated, along with the best jointpoint adjustment using Jointpoint regression. RESULTS: 7,696 cases were analyzed, 48.2% were foreign-born individuals. Average age in native population was 50 years old (SD: 23.96) and 35 (DS: 36.64) in foreign-born individuals (p<0.001). The overall incidence rate decreased from 17.30 in 2009 to 9.00 per 100,000 in 2018 and was higher in men. Pulmonary tuberculosis reduced from 11.90 to 6.55. Among native population, the incidence of TB fell from 10.29 to 5.24 with an APC of -7.3% (95%IC: -8.9; -5.7) (p<0.05), no jointpoint was identified. Among foreign-born individuals the incidence of tuberculosis declined from 46.54 to 25.49, a joint point was identified in 2013, observing an incidence decrease for the period 2009-2013 and APC of -13.8% (IC95%: -17.5; -10.0). CONCLUSIONS: The global incidence rate in this period has decreased by approximately 7% per year. However, this reduction occurred mainly in native population. In foreign-born individuals the incidence decreased by approximately 14% during the 2009-2013 period, after this period there have been no significant incidence changes.
OBJETIVO: La tuberculosis (TB) continúa siendo un problema importante de salud pública, debido a que la mayoría de los casos se concentran en población vulnerable. El objetivo de este trabajo fue describir la tendencia de las tasas de incidencia en población autóctona y extranjera (2009-2018) en la Comunidad de Madrid (CM). METODOS: Se realizó un análisis retrospectivo de casos del Registro Regional de casos de Tuberculosis de la CM en el período 2009-2018. Se calcularon tasas de incidencia anual por cada 100.000 habitantes, por país de nacimiento (España, fuera de España), sexo y grupo de edad (<15, 15-34, 35-44, 45-64, >64), utilizando las poblaciones de padrón continuo a 1 de enero de cada año. Se calculó la tendencia de las tasas de incidencia y el porcentaje anual de cambio (APC), así como el mejor ajuste del punto de inflexión utilizando la regresión de Jointpoint. RESULTADOS: Se analizaron 7.696 casos, siendo el 48,2% en personas nacidas fuera de España. La edad media en población autóctona fue de 50 años (DS: 23,96) y 35 (DS: 36,64) en inmigrante (p<0,001). La tasa de incidencia global pasó de 17,30 por cada 100.000 habitantes en 2009 a 9 en 2018, siendo superior en hombres. La incidencia de tuberculosis pulmonar pasó de 11,90 a 6,55. En población autóctona, la incidencia de TB pasó de 10,29 a 5,24, con un APC de -7,3% (IC95%: -8,9; -5,7; p<0,05), y no se identificó ningún punto de inflexión. En población extranjera la incidencia de tuberculosis pasó de 46,54 a 25,49, identificándose un punto de inflexión en 2013, con una disminución más acusada de la incidencia para el periodo 2009-2013 debido a un APC de -13,8% (IC95%: -17,5; -10,0). CONCLUSIONES: La tasa de incidencia global en este periodo disminuye cerca de un 7% anual; sin embargo, esta disminución de la incidencia se produce fundamentalmente en población autóctona. En población extranjera la incidencia desciende cerca de un 14% durante el periodo 2009-2013. Tras este periodo no hay cambios significativos en la incidencia.

BACKGROUND AND OBJECTIVE: The availability of antipneumococcal vaccines makes it necessary to go deeply into the knowledge of pneumococcal disease. This study aims at describing the magnitude and incidence of pneumococcal disease in the Region of Madrid from 1998 to 2006. MATERIAL AND METHOD: Retrospective study of Computerized Hospital Discharge Data registered from 1998 to 2006. Incidence per 100,000 inhabitants and lethality were calculated. Temporal evolution was analyzed. RESULTS: 20,813 cases of pneumococcal disease were registered (annual average incidence 41.87/100,000 inhabitants). Incidence was 40.65 for pneumoniae and 0.77 for meningitis. People over 64 years old (185.04) and under 1 year of age (67.22) showed the highest incidence. Lethality was 10.1% (15.8% for meningitis). Incidence in 2004--2006 was lower than 1998--2000 (before the introduction of conjugate vaccine). Incidence trend has declined slightly. CONCLUSIONS: The incidence is higher than that shown by other studies. Selected source of data can explain this difference, since our data included suspected cases. However, pneumococcal meningitis incidence is similar to that described by others.

BACKGROUND: Chickenpox is a contagious airborne disease. Immunization by varicella vaccine is an effective preventive measure. The objective of this study is to evaluate the impact and effectiveness of a single-dose vaccination against chickenpox at 15 months of age. METHODS: Observational study based on data from the Epidemiological Surveillance System of the Autonomous Community of Madrid from 2001 to 2015. The years were grouped into 4 periods according to epidemic cycles and vaccination schedule: 2001-06, 2007-10, 2011-13 and 2014-15. The impact was calculated as Relative Risk (RR) between the incidence of chickenpox in children between 15 months and 13 years of age between 2011-13 and 2001-06 through Poisson regression using notifications made to the Diseases of Compulsory Declaration (DCD) system, the Sentinel Physicians Network (SPN) and hospital discharge records noted as Minimum Basic Data Set (MBDS). The vaccine effectiveness (VE) was calculated using the screening method and a 1:2 case-control study paired by age and paediatrician in population from 15 months to 13 years and between 2007 and 2015 using SPN source data. RESULTS: The RR2011-13/2001-06 using data from the DCD was 0.14 (95% CI: 0.14 to 0.15), 0.07 (95% CI: 0.06 to 0.08) from SPN and 0.17 (95% CI: 0.15 to 0.20) from MBDS. A total of 338 cases were included in the VE screening obtaining an overall of 76.7% (IC 95%: 71.9 to 80.7%). For a case-control study, 120 cases and 247 controls were recruited obtaining a VE of 92.4% (IC 95%: 80.8 to 97.0%). CONCLUSIONS: The single-dose vaccination against chickenpox at 15 months of age has high impact and effectiveness.

BACKGROUND: Immigration from countries having a high prevalence of tuberculosis to other more highly-developed countries has a bearing on the overall evolution of tuberculosis in the latter. This study is aimed at describing the influence of the cases of tuberculosis among foreign individuals on the incidence of this disease in the Autonomous Community of Madrid during the 1996-2004 period. METHODS: The data was taken from the Regional Tuberculosis Case Registry and from the 1996 census and the continuous censuses from 1998 to 2004. The tuberculosis incidence was estimated by country of origin from 1996 to 2004, by gender and by age groups. A calculation was made of the c2 for the linear trend, reasons for incidence and proportion of cases among foreign individuals. RESULTS: The incidence of tuberculosis went from 34.3 cases per 105 inhabitants in 1996 to 16.9 cases per 105 inhabitants in 2004. For those born in Spain, it changed from 33.2 cases per 105 inhabitants in 1996 to 12.7 cases per 105 inhabitants in 2004; and for foreign individuals, from 50.5 cases per 105 inhabitants in 1996 to 42.9 cases per 105 inhabitants in 2004. The reason for the incidence between foreign and Spanish individuals was greater than 1 for all years, the maximum figure having been in 2003, when 4.2 cases were detected among foreigners for every case among Spanish individuals (95% CI 3.7-4.7). The percentage of foreign cases went from 5.2% in 1996 to 35.1% in 2004. CONCLUSIONS: The incidence of tuberculosis among foreigners was greater than among Spanish individuals and did not significantly decrease in the 1996-2004 period, which is contributing to tuberculosis having stabilized. This situation and the characteristics of this population must be taken into account in the efforts for controlling this disease.
