Analysis of the two asymptomatic cases of H5N1 avian influenza detected in Spain in autumn 2022 in workers at a poultry farm in Guadalajara has confirmed the theory that no actual infections occurred, but that both were in contact with genetic material of the virus found in the environment. Spain has recently modified its protocols, according to the analysis published in Eurosurveillance.
After the World Cup in Qatar, National Microbiology Centre researcher María Iglesias wonders where the social alarm about an alleged outbreak of MERS came from and takes the opportunity to explain some concepts of the virus and its surveillance.
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.
In a briefing organised by the Science Media Centre Spain, Amparo Larrauri and Francisco Pozo, researchers at the Health Institute Carlos III, explained how three respiratory viruses are coexisting this autumn: influenza virus, respiratory syncytial virus (responsible for most bronchiolitis) and SARS-CoV-2.
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 in The Lancet Infectious Diseases analyses the response of seven monkeypox patients diagnosed in the UK between 2018-2021, treated with the antivirals brincidofovir and tecovirimat.
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.
Following the detection of several cases of people infected with the simian smallpox virus in the UK, health authorities are concerned that there may be EU-wide transmission with undetected infections, both within and outside the country. In Spain, the Community of Madrid has identified 23 possible cases of infection.
In the first months of 2022, avian influenza has hit birds in Spain with unprecedented intensity. All outbreaks are now closed and the epidemiological situation is favourable, but we must not let our guard down. The risk of the virus jumping to humans is considered low.
Climate change will lead to at least 15,000 new cross-species virus transmissions by 2070, as habitat shifts on a 2°C warmer planet will bring previously distant animals closer together. This result, published in Nature, points to increased exposure of humans to pathogens from wild animals.
