RESUMO
In September 2018, monkeypox virus was transmitted from a patient to a healthcare worker in the United Kingdom. Transmission was probably through contact with contaminated bedding. Infection control precautions for contacts (vaccination, daily monitoring, staying home from work) were implemented. Of 134 potential contacts, 4 became ill; all patients survived.

During August 2015, a boil water notice (BWN) was issued across parts of North West England following the detection of Cryptosporidium oocysts in the public water supply. Using prospective syndromic surveillance, we detected statistically significant increases in the presentation of cases of gastroenteritis and diarrhoea to general practitioner services and related calls to the national health telephone advice service in those areas affected by the BWN. In the affected areas, average in-hours general practitioner consultations for gastroenteritis increased by 24.8% (from 13.49 to 16.84) during the BWN period; average diarrhoea consultations increased by 28.5% (from 8.33 to 10.71). Local public health investigations revealed no laboratory reported cases confirmed as being associated with the water supply. These findings suggest that the increases reported by syndromic surveillance of cases of gastroenteritis and diarrhoea likely resulted from changes in healthcare seeking behaviour driven by the intense local and national media coverage of the potential health risks during the event. This study has further highlighted the potential for media-driven bias in syndromic surveillance, and the challenges in disentangling true increases in community infection from those driven by media reporting.

Infant botulism is a rare disease in the UK, with the first case being recognized in 1978 and only five subsequent cases being reported before 2007. This study reports two unlinked cases of infant botulism, caused by two distinct strains of Clostridium botulinum (toxin types A and B, respectively), that occurred within a single month in the south-east of England in October 2007. The use of real-time PCR to detect C. botulinum neurotoxin genes in clinical specimens to improve the diagnostic procedure and to follow carriage of the causative organism in the infant gut is described. The laboratory investigation of these two cases demonstrated that a combination of the mouse bioassay, real-time PCR assays and conventional microbiological culture can provide rapid confirmation of a clinical diagnosis and affect patient management. Both infants (aged 4 and 8 months) were previously healthy prior to the onset of symptoms, and in both cases, a diagnosis of infant botulism was delayed for at least 10 days after initial admission to hospital. Once diagnosed, one of the infants was the first in the UK to be treated with human-derived botulism immunoglobulin. Real-time PCR was used to demonstrate that C. botulinum was excreted in the infants' faeces for up to 68 and 81 days, respectively. Despite the infrequency of infant botulism in the UK, clinicians should be aware of this rare but serious condition and should seek microbiological advice when presented with young infants with compatible symptomologies.

We measured the hepatitis B (HB) vaccination uptake in 249 London babies born in 2004 to HBsAg positive mothers. Two thirds (69%) received three vaccinations and half (49%, 95% CI 43-56) received a complete course (four doses). Complete immunization was associated with sector of delivery (p<0.001), recording of the GP details in case notes, having booked for antenatal care, having a good command of English, and receipt of written information on HB. A third of the babies (33%) had a post-vaccination test; when the mother had other children, 39% of the oldest children were vaccinated; information on partner's vaccination was available for 12%. This study highlights that appropriate counseling and information should be provided to the mothers, and the importance in London of arrangements for integrated care across acute and primary care services.
