ABSTRACT
A total of 752 horses were involved in the CES Valencia Spring Tour 2021. Due to an equine herpesvirus-1 (EHV-1) outbreak, the competition was cancelled and the site was locked down. The objective of this study was to describe epidemiological, clinical, diagnostic, and outcome data of the 160 horses remaining in Valencia. Clinical and quantitative polymerase chain reaction (qPCR) data were analysed for 60 horses in a retrospective case-control observational study. The risk of developing clinical manifestations was explored using a logistic regression approach. EHV-1 was detected by qPCR, genotyped as A2254 (ORF30) and isolated on cell culture. From the 60 horses, 50 (83.3%) showed fever, 30 horses (50%) showed no further signs and 20 (40%) showed neurological signs, with eight horses (16%) hospitalised, of which two died (3%). Stallions and geldings were six times more likely to develop EHV-1 infection compared to mares. Horses older than 9 years, or housed in the middle of the tent were more likely to develop EHV-1 myeloencephalopathy (EHM). These data show that for EHV-1 infection, the risk factor was male sex. For EHM the risk factors were age > 9-year old and location in the middle of the tent. These data highlight the crucial role of stable design, position, and ventilation in EHV-outbreaks. It also showed that PCR testing of the horses was important to manage the quarantine.

Se realizó un estudio retrospectivo de las 1596 pacientes que parieron en el cuatrimestre Enero, Abril del 2002 en el Hospital General Docente Ernesto Guevara de la Serna con el objetivo de conocer la infección puerperal; se demostró un predominio de partos por vía transpelviana. La infección puerperal se comportó de manera de similar en el parto transpelviano y por cesárea con 17 y 13 casos respectivamente. Las causas más frecuentes fueron la endometrítis, sepsis urinaria y la sepsis de la herida quirúrgica tanto en el parto transpelviano como en la cesárea, el germen que predomino fue la Echericha coli(AU)
A retrospective study of 1596 female patients whose delivery took place from January to April 2002 was carried out in Ernesto Guevara de la Serna General Teaching Hospital with the objective toresearch on the incidences of puerperal infection the predominant number, 17, was for the patients with a transpelvic via delivery, and 13 for cesarian section. In the two cases the most frequent causes of infections were endometritis, urinary sepsis and sepsis in the wound and the germ was Echerichacoli(AU)
