In June, 207 people died in Hego Euskal Herria from heat and 27 others died in the first four days of July

There have been 153 deaths attributable to high temperatures in the first days of July throughout the Spanish state, and about 1,000 (937) were recorded last June, according to data from the Daily Mortality Monitoring System(MoMo) of the Carlos III Health Institute.

In June, the Autonomous Community of the Basque Country recorded the highest number of deaths attributable to heat, namely 153 and Katalunia 127. 

In the other communities, deaths from high temperatures were recorded in June: 73 in Andalusia; 45 in Aragón; 51 in Asturias; 50 in Cantabria; 90 in Castilla y León; 30 in Castilla-La Mancha; 62 in Comunidad Valenciana; 7 in Extremadura; 88 in Galicia; 93 in Madrid; 3 in Murcia; 54in Navarra; and 13 in La Rioja.

In the Balearic Islands, the Canary Islands, Ceuta and Melilla there were no heat-related deaths.

In the first four days of July, according to data published by the Momo system of the Carlos III Health Institute (Ministry of Science, Innovation and Universities), 24 deaths have already been recorded in Andalusia; 3 in Aragón; 3 in Asturias; 6 in Cantabria; 5 in Castilla y León; 3 in Castilla-La Mancha; 57 in Catalonia; 6 in Comunidad Valenciana; 6 in Extremadura; 6 in Galicia; 4 in Madrid; 9in Navarra; 18in Euskadi; and 1 in Rioja.

What is the Momo system, and how does it work?

The MoMo system examines daily mortality for all causes, including those associated with high temperatures in the  range, but not only doesit count deaths from a heat stroke, but all deaths that may be associated with the worsening of other heat diseases (usually cardiovascular, respiratory, or kidney).

The MoMo system estimates overmortality by comparing the deaths that have occurred with those expected in a given territory and period. It makes it possible to detect this additional mortality for all causes, and therefore to estimate deaths attributable to events of extreme temperatures, such as heat or cold. However, it does not determine the individual causesof death, but the patterns associated with heat waves, intense cold, or other periods of overmortality.

This system publishes the figures every day, but these are not definitive, because it recalculates the numbers continuously, increases the number of deaths that may have been reported late in the basement, so that the figures are constantly updated, and are not considered final and consolidated until several weeks later.
