      PERTOSSE in AUMENTO malgrado il VACCINO per la Pertosse....
      COMMENTO
      La celebre e prestigiosa rivista medica Jama pubblica un interessante 
articolo sul numero del 10 dicembre 2003. Vi alleghiamo di seguito 
l'abstract ricavabile da Med-Line ( 
www.nlm.nih.gov
).
      Vi si riporta che i casi di pertosse sono cresciuti tra gli 
adolescenti e gli adulti  in concomitanza con un innalzamento delle 
coperture vaccinali di neonati e bambini a partire dal 1980, con un aumento 
dei casi negli anni '90 rispetto agli anni '80.

      CONTEXT: Reported cases of pertussis among adolescents and adults have 
increased since the 1980s, despite increasingly high rates of vaccination 
among infants and children. However, severe pertussis morbidity and 
mortality occur primarily among infants. OBJECTIVE: To describe the trends 
and characteristics of reported cases of pertussis among infants younger 
than 12 months in the United States from 1980 to 1999. DESIGN, SETTING, AND 
PARTICIPANTS: Cases of pertussis in infants younger than 12 months in the 
United States reported to the National Notifiable Disease Surveillance 
System of the Centers for Disease Control and Prevention between 1980 and 
1999, and detailed case data from the Supplementary Pertussis Surveillance 
System. MAIN OUTCOME MEASURES: Incidence and demographic and clinical 
characteristics of cases. RESULTS: The incidence of reported cases of 
pertussis among infants increased 49% in the 1990s compared with the 
incidence in the 1980s (19 798 vs 12 550 cases reported; 51.1 cases vs 34.2 
cases per 100 000 infant population, respectively). Increases in the 
incidence of cases and the number of deaths among infants during the 1990s 
primarily were among those aged 4 months or younger, contrasting with a 
stable incidence of cases among infants aged 5 months or older. The 
proportion of cases confirmed by bacterial culture was higher in the 1990s 
than in the 1980s (50% and 33%, respectively); the proportion of 
hospitalized cases was unchanged (67% vs 68%, respectively). Receipt of 
fewer doses of vaccine was associated with hospitalization, when cases were 
stratified by age in months. CONCLUSIONS: The incidence of reported cases of 
pertussis among infants increased in the 1990s compared with the 1980s.
      The limited age group affected, the increased rate of bacteriologic 
confirmation, and the unchanged severity of illness suggest that an increase 
in infant pertussis has occurred apart from any change in reporting. 
Strategies are needed to prevent the morbidity and mortality from pertussis 
among infants too young to be fully vaccinated, according to the current 
recommended schedules of vaccination in the United States.

che tu non hai letto o non hai capito altrimenti non l ' avresti postato 
dal momento che l ' articolo 
- NON dice che NON ci si deve vaccinare 
- che le vaccinazioni fatte negli anni 80 era meglio farle in una fascia di
eta' piu' inoltrata
- come stanno facendo ora negli Stati Uniti 
buonasera eh !
