In Spain, whole cell pertussis vaccination started in 1975, with three doses before the age of 6-7 months. Doses at 15-18 months and 4-6 years were introduced in 1996 and 2001, respectively. Spain switched to an acellular vaccine in 2005. From 1998 to 2009, pertussis incidence rates remained ≤1.5 cases/100,000 inhabitants but increased from 2010 to 7.5(More)
OBJECTIVE To identify risk factors predictive of nosocomial infection in an intensive-care unit (ICU) and to identify patients with a higher risk of nosocomial infection using a predictive model of nosocomial infection in our ICU. DESIGN Prospective study; daily concurrent surveillance of intensive-care-unit patients. SETTING/PATIENTS All patients(More)
Objective: Comparison of statistical methods and measurement scales to identify nosocomial infection risk factors in intensive care units (ICU). Design: Prospective study in 558 patients admitted to the ICU of a referral hospital between February and November 1994. Methods: Analysis using three logistic regression models, three standard Cox regression(More)
Enterovirus D68 was known to be the cause of mild to severe respiratory infections, but in the last few years it has also been associated with myelitis and paralysis. This report describes the first EV-D68 detections in acute flaccid paralysis cases occurring between December 2015 and March 2016 in Spain.
The mumps vaccine (Jeryl-Lynn-strain) was introduced in Spain in 1981, and a vaccination policy which included a second dose was added in 1995. From 1992-1999, a Rubini-strain based vaccine was administered in many regions but later withdrawn due to lack of effectiveness. Despite high levels of vaccination coverage, epidemics have continued to appear. We(More)
BACKGROUND Pertussis is a re-emerging disease worldwide despite its high vaccination coverage. European and Latin-American countries have used different surveillance and vaccination policies against pertussis. We compared the epidemiology of this disease in two Ibero-American countries with different vaccination and surveillance policies. METHODS We(More)
