In recent weeks, the UK Health Safety Agency has detected an unusual increase in infections with Streptococcus pyogenes bacteria. At least 13 children under the age of 15 have died from this pathogen, which is responsible for mild infections but also for more serious conditions such as invasive disease. The Spanish Society of Paediatric Infectious Diseases has reported that there have been some deaths in Spain - the Community of Madrid has reported two deaths - and is analysing whether there has been an unusual increase in cases. 
 

The UK Health Safety Agency (UKHSA) has detected an unusual increase in Streptococcus pyogenes infections in the last month. This bacterium is responsible for mild infections, but also for more serious conditions such as scarlet fever and, above all, invasive disease. The British authorities have raised the alarm after at least eight children died from this pathogen. In Spain, the Spanish Society of Paediatric Infectious Diseases has reported that there have also been some deaths and is analysing whether there has been an unusual increase in cases.

The WHO has published the first list of priority fungal pathogens, which affect more than 300 million people and kill at least 1.5 million people every year. However, funding to control this scourge is less than 1.5 % of that devoted to infectious diseases.

The first study of UK cases of the current monkeypox outbreak finds differences between the symptoms of these patients and those of previous outbreaks in other parts of the world. The work is published in the journal The Lancet Infectious Diseases.

The rise in cases of asthma, allergies and digestive tract diseases, among others, could be linked to changes in the microbiome. US researchers are propose to combat this trend by having us all save samples of our own gut microbiota when we are young and healthy, for later use in an autologous faecal microbiota transplant.

Communicating outbreaks of infectious diseases is not easy, especially when they affect population groups that may face discrimination. Cases of monkeypox among men who have sex with men remind us of the importance of reporting without stigma.

The UK has detected "circulating vaccine-derived poliovirus type 2" in residual samples collected between February and June. Although no symptomatic cases have been found so far, the finding underlines the importance of keeping the population vaccinated.

Respiratory Syncytial Virus (RSV) was responsible for more than 100,000 deaths in children under the age of five worldwide in 2019, a study published in The Lancet estimates. The authors highlight the "urgent need" for vaccines.
