Flu Threatens Christmas as Health Authorities Issue Warnings Across Europe

As Christmas celebrations draw near and families prepare to gather, hug, and exchange kisses, health systems across Europe are sounding the alarm over a rapid spread of influenza, with hospitals approaching capacity.

In Spain, the latest data from the Carlos III Health Institute show that flu cases are still rising, albeit at a slower pace. 

During the 50th week of the year, infection rates exceeded 446 cases per 100,000 people. While the curve has begun to level off, experts warn that the country is nearing the peak of the outbreak at a particularly sensitive time that coincides with the Christmas holidays, according to Spain’s 20 Minutos newspaper.

Doctors, especially in emergency departments, report a noticeable increase in hospital admissions, particularly among the elderly, patients with heart and respiratory conditions, those with chronic illnesses, and infants. 

The Spanish Society of Emergency Medicine says that influenza A is currently the dominant strain, with two highly contagious subvariants driving the growing pressure on healthcare services.

Health officials caution that the main risk lies not only in the virus itself, but also in large family gatherings and indoor celebrations, where infections spread easily through close contact, droplets, and traditional holiday greetings such as kisses.

Authorities are urging preventive measures during the festive season, including avoiding close contact when symptoms appear, frequent handwashing, and wearing masks in crowded places.

Although Spanish media have not issued a blunt “no kissing at Christmas” warning, the message is clear: holiday joy can quickly turn into illness if precautions are ignored. This Christmas, many Europeans face a difficult balance, how to celebrate safely without overwhelming health systems once the festivities end.
