Scabies and bedbugs: pests return to Madrid-Barajas airport

Scabies and bedbugs: the return of pests we thought were gone

Diseases that epidemiology textbooks considered nearly eradicated are back in the headlines. Scabies, bedbugs and other conditions linked to overcrowding are behind outbreaks in schools, hotels and even Terminal 4 of Adolfo Suárez Madrid-Barajas airport, where more than 30 workers have suffered bites in the past month. This is no minor issue: it points to a public health problem, but also to a failure of infrastructure management.

An airport as an infection hotspot

The reports coming out of Barajas are not about delays, but about parasites. According to the information released, bedbugs, fleas, ticks and cockroaches have turned Terminal 4 into a hotspot that directly affects staff. One worker says that after sitting down for 15 minutes, she accumulated between 30 and 40 bites. The number of homeless people sleeping at the airport has multiplied tenfold, according to complaints from the employees themselves. The measures taken so far have not brought the situation under control.

Who is to blame: the debate over the origin

In the face of these outbreaks, a narrative has emerged blaming the resurgence on the arrival of migrants. That story, however, clashes with the data from Spain's public health system itself: scabies and bedbugs thrive in cities without large migration flows and spread in nurseries, care homes and overcrowded transport systems. Some argue the key lies in structural conditions: overcrowding, understaffed sanitation services and cuts to public health. The evidence suggests parasites don't care about passports, but they do thrive on poor hygiene and poor oversight.

If the Barajas outbreak teaches us anything, it's that modern medicine can treat the itching but cannot replace prevention. Outbreaks will keep appearing as long as the link between public health and material conditions is ignored. Next time a story about scabies makes the news, perhaps we shouldn't look at who is arriving, but at who is receiving them.
