Hepatitis A at a nursery on Gran Canaria: what happened — and what parents need to know

Let's start with the established facts. The starting point was a sick child at a nursery on Gran Canaria; the protocol that was then triggered uncovered five more cases — all in children. Two of the small patients needed brief hospital treatment but have already been discharged; the others are being monitored at home. The responsible health councillor stressed that all the children are in good health. A few days after it came to light, the outbreak is officially considered controlled.

What hepatitis A is — and what it isn't

An important distinction is needed here, one that headlines often blur: hepatitis A is not the same as hepatitis B or C. While B and C are spread mainly through blood and bodily fluids and can become chronic, hepatitis A is a liver inflammation transmitted faecal-orally — that is, through traces of stool, usually via contaminated hands, food or water. That is precisely why it occurs more often where many people are in close quarters and hygiene matters most, such as nurseries.

The good news: hepatitis A almost always clears up on its own and does not become chronic. In young children in particular it is often mild, sometimes even without symptoms. Typical signs, when they appear, are fatigue, nausea, loss of appetite, abdominal pain and — the best-known sign — a yellowing of the skin and eyes (jaundice).

What the authority is doing

The approach follows a well-rehearsed protocol. At its centre is so-called post-exposure vaccination: children and staff at the nursery who are not yet immunised are vaccinated, alongside diagnostic tests of close contacts through primary care. Notably, what the authority expressly does not consider necessary: the nursery need take no special measures — beyond the hygiene rules recommended anyway. Closure is not on the table.
