Monkeypox outbreak predominantly affecting men who have sex with men, Madrid, Spain, 26 April to 16 June 2022.

Up to 22 June 2022, 508 confirmed cases of monkeypox (MPX) have been reported in the Madrid region of Spain, 99% are men (n = 503) with a median age of 35 years (range: 18-67). In this ongoing outbreak, 427 cases (84.1%) reported condomless sex or sex with multiple partners within the 21 days before onset of symptoms, who were predominantly men who have sex with men (MSM) (n = 397; 93%). Both the location of the rash, mainly in the anogenital and perineal area, as well as the presence of inguinal lymphadenopathy suggest that close physical contact during sexual activity played a key role in transmission. Several cases reported being at a sauna in the city of Madrid (n = 34) or a mass event held on the Spanish island of Gran Canaria (n = 27), activities which may represent a conducive environment for MPX virus spread, with many private parties also playing an important role. Because of the rapid implementation of MPX surveillance in Madrid, one of the largest outbreaks reported outside Africa was identified. To minimise transmission, we continue to actively work with LGBTIQ+ groups and associations, with the aim of raising awareness among people at risk and encouraging them to adopt preventive measures.

[Outbreak of Trichophyton tonsurans ringworm in a health area of the Community of Madrid (Spain)]. / Epidemia de tiña por Trichophyton tonsurans en un área sanitaria de la Comunidad de Madrid (España).

BACKGROUND: Trichophyton tonsurans is a dermatophyte fungus that can cause ringworm outbreaks. In our health area in September 2013, two cases of T. tonsurans ringworm were diagnosed in children who lived in a Children's Centre. AIMS: To determine the origin and extent of the outbreak. METHODS: Mycological cultures of scalp and skin samples from the contacts of the diagnosed cases were performed, as well as environmental samples from the Children's Centre. The patients started with a treatment for their ringworm, and an environmental disinfection of the centre was performed. RESULTS: Twelve cases of ringworm were detected, along with three asymptomatic scalp carriers of T. tonsurans among 20 children in the Centre. The index case was a resident in whose family, that had just returned from their country of origin, Nigeria, three cases of ringworm were diagnosed. From November 2013 to February 2014 another five cases of ringworm were diagnosed among schoolmates of three cases from the Children's Centre. CONCLUSIONS: The antifungal treatment of the children resulted in the mycological and clinical resolution, and from February to November 2014 no other cases of ringworm by T. tonsurans in the same health area were diagnosed.

[Outbreak of Legionnaires' disease in a restaurant in the Community of Madrid, Spain]. / Brote de legionelosis en un restaurante de la Comunidad de Madrid.

BACKGROUND: on June 27, 2012, 46 cases of community- acquired Legionnaires'disease were detected in the Public Health Service area 8 of the Community of Madrid. All of them had been in the same restaurant of the city of Móstoles within the incubation period of the disease. METHODS: this is a descriptive study. Variables studied in the patients were: demographic data, medical history, symptoms, clinical course and diagnostic tests. For qualitative variables, frequencies and percentages were calculated. For quantitative variables, mínimum, máximum and average of values were calculated. In water samples taken on risk devices, we studied chlorine concentration, pH, temperatura and presence of Legionella. RESULTS: Legionella pneumophila Serogrupo 1, Subgrupo Pontiac Allentown/France was isolated from the water culture from the sand filter of the outside fountain's treatment plant; this result coincided with the strain isolated from respiratory samples of 4 patients. On the other hand, in biofilm samples obtained from the champagne bucket it was detected by PCR the presence of Legionella pneumophila whose gene sequencing was identical to that found in a respiratory sample of one patient. CONCLUSION: Legionella pneumophila serogroup 1 subgroup Pontiac Allentown/France serotype 448 was isolated in water samples, and this Legionella coincided with the one isolated from respiratory samples of some patients. So, we could show the link between environmental risk factor and the disease. This link was also confirmed by genetic sequencing with PCR.
