Living near green spaces over a long period of time is associated with better health, an association more marked in women and white people than in men and black people, according to a study conducted in four US cities. The analysis concludes that exposure to urban green space between 1985 and 2006 is associated with slower epigenetic ageing, and that this association is stronger in disadvantaged neighbourhoods. The international team publishing this paper in Science Advances includes a researcher from ISGlobal in Barcelona. 

From May to August 2022, 157,580 deaths were recorded, 20.5% more than in the same months of 2019, before covid. This increase in mortality was mainly among people aged 75 years and older. Of the causes of death directly related to the heat, heat stroke and dehydration stood out. These are some of the provisional data published by the National Statistics Institute (INE) in relation to deaths in 2022. Covid-19 was the most frequent cause of death, with 31,559 people dying, 20% less than in 2021.

People who had a lower respiratory tract infection—such as bronchitis or pneumonia—before the age of two have twice the risk of premature death from respiratory disease in adulthood, according to a study published in The Lancet. The research is based on long-term data from over 3,500 people born from 1946 onwards in England, Scotland and Wales. According to the study, one in five premature deaths in this representative sample could be due to respiratory infections. The team adjusted their estimate by taking into account factors such as socioeconomic status in childhood and smoking in adulthood.  

In the last few days, several media have published that the end of the obligatory use of face masks in public transport is near. According to today's Vozpópuli, the Alerts Committee is expected to approve the change from compulsory to recommended use next week.

This week the National Statistics Institute (INE) shared the final figures for deaths by cause of death for the year 2021: 39,444 people died from identified covid-19, 34.6% less than in 2020. It also offered preliminary data for the first six months of 2022.

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.

The WHO's Global Influenza Surveillance and Response System recorded outliers for influenza illness in 16 countries, including Spain, in early 2020. This would mean an average of 13 weeks before the first reported covid-19 peak, according to research published in PLoS Medicine.

A study published today in The Lancet claims that there are no benefits to alcohol consumption for young people between the ages of 15 and 39. However, the authors claim that in adults over the age of 40 consuming a small amount may confer some health benefits.

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.
