A study of nearly 3,000 Latin Americans who attended the Hospital Clínic in Barcelona over 17 years showed that 47% were infected by the parasite that causes Chagas disease. Of these, 17% also presented cardiac alterations derived from the disease. The study reveals that there is under-diagnosis in Spain, as there is in endemic areas. However, due to the characteristics of the research, the authors point out that "these data cannot be used to estimate the prevalence of infection in the general Latin American population living in Spain", which is notably lower according to other studies. The results are published in the journal PLoS Neglected Tropical Diseases.

The Centre for the Coordination of Alerts and Health Emergencies (CCAES) reported yesterday that last February Germany reported two cases of dengue (one confirmed and one probable), along with four cases compatible with epidemiological links, in residents of Germany who had travelled to Ibiza during the incubation period. One of the potential vectors of dengue is the Aedes albopictus mosquito, which was first detected in Ibiza in 2014. According to the CCAES, the risk of new autochthonous cases appearing in Ibiza, "at this time of low vector activity, is considered low".

Several media outlets are reporting cases of "camel flu" or MERS-CoV at the World Cup in Qatar, including three French national team players. However, no cases have been confirmed and the news reports speak of non-specific symptoms that could be due to any other infectious condition. This coronavirus, discovered in 2012, has a high case fatality rate and before the start of the competition, the WHO had already asked fans travelling to the country to watch out for possible symptoms.

The Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has recommended granting marketing authorisation for the tetravalent dengue vaccine (live, attenuated) Takeda. The vaccine is intended to prevent disease caused by dengue virus serotypes 1, 2, 3 and 4 in people aged four years and older. Although an approved vaccine already exists, according to the EMA, this quadrivalent vaccine shows increased protection in children and people over 45 years of age.

A study published today in The Lancet examines the clinical manifestations of monkeypox in 181 patients at three sexual health clinics in Madrid and Barcelona.

A study published today analyses 185 cases of monkeypox reported in Spain up to 11 July.

Today the World Health Organisation declared smallpox a Public Health Emergency of International Concern. The move was announced at a press conference by its director general, Tedros Adhanom, despite a lack of consensus in the International Health Regulations Emergency Committee.

Castilla-La Mancha has sealed a farm in Toledo after a minor was hospitalised (and later discharged) after drinking water from a tap. Analyses by the Instituto de Salud Carlos III have confirmed that it is not cholera. Although the bacteria consumed is the same, in this case it did not contain the toxins that cause the disease.

On 18 May, the Ministry of Health confirmed to SMC Spain that eight suspected cases "clinically compatible" with monkeypox had been detected. The same afternoon, the Consejería de Sanidad de la Comunidad de Madrid reported that it had detected 23 possible cases of infection. These cases need to be confirmed after testing. At least 7 cases have been confirmed in the UK and Portugal. This is a rare zoonotic viral disease and there is no vaccine or specific treatment available. Treatment is symptomatic and supportive. Most cases are resolved favourably.
