A four-year-old holidaymaker from Austria was treated with antivenom at KBC Rijeka and is in a stable condition. The campsite has not been named. What is confirmed about the case – and what to do after a snakebite.
What is confirmed about the case in Istria
A four-year-old holidaymaker from Austria was bitten in Istria on 21 August 2026 by a snake described in reports as a nose-horned viper, or poskok. According to information reported by HRT, the bite occurred at an unnamed campsite when the child lifted a small stone while playing outdoors.
The child was taken to the Clinical Hospital Centre Rijeka for treatment and received antivenom. On 23 August, paediatric surgeon Marko Radman said that the boy was stable and out of danger. Health Minister Irena Hrstić also confirmed his stable condition and said Croatia had sufficient stocks of the required antivenom.
The campsite rightly remains unnamed
Neither the name nor the precise location of the campsite was published in the reliable report. There is also no evidence of negligence by the operator, an unusual concentration of snakes or a danger to other guests. Golden Beach therefore names no suspected business and does not turn this individual case into a campsite warning.
Snakes are part of the natural environment in Istria and other regions of Croatia. An animal under a stone is not evidence of a poorly maintained campsite. The key issue here is not finding someone to blame but the medical response after the bite and simple precautions when playing, hiking and working outdoors.
Why small children require particularly close monitoring
The paediatric surgeon treating the boy pointed to children's lower body weight: even a smaller quantity of venom can have more severe effects in relation to their size. Children therefore need rapid specialist assessment and particularly close monitoring after a possible venomous-snake bite.
That does not mean parents should estimate the amount of venom or severity themselves. Even a bite that initially looks minor can change. The Croatian Institute of Public Health, HZJZ, treats every venomous-snake bite as a medical emergency and advises against waiting for clear symptoms.
The first minutes: call 112, reassure and immobilise
The official HZJZ guidance says to call 112 or the emergency medical service immediately. The bitten person should lie down or sit still, move as little as possible and be reassured. The affected arm or leg should be immobilised without restricting blood flow.
Remove rings, watches and tight items before swelling develops. The bite site can be covered with a clean, dry dressing. Marking the edge of any swelling and noting the time helps the medical team track its progression – but in no way replaces prompt transport for treatment.

The first minutes
What is expressly harmful after a snakebite
Do not cut the wound, suck out the venom or apply ice. Tying off the limb with a belt, cord or tourniquet can cause additional tissue damage and is not first aid. Do not immerse the affected area in water. HZJZ also advises avoiding alcohol as well as aspirin or ibuprofen.
Nobody should try to catch or kill the snake to take it to hospital. Exact species identification is not required for medical care. A photograph may be useful if it can be taken from a safe distance without delay or approach, but personal safety and the emergency call take priority.
The nose-horned viper is recognisable – but camouflage beats the textbook
The nose-horned viper, Vipera ammodytes, is often described by its dark zigzag pattern and small horn at the tip of its snout. Colour, markings and visibility can vary, however. Among pale karst, leaves, dry-stone walls and grass, an animal can disappear from view much faster than a field-guide photograph suggests.
Keeping your distance is therefore more important than making a certain identification. Croatia's Environment Ministry lists the common European adder and meadow viper alongside the nose-horned viper as native venomous snakes. Anyone who sees a snake should stop, back away calmly and leave it an escape route. Touching, harassing or pulling it out with a stick is the wrong response.
Stones, wood and shoes: prevention without fear
Children should not lift stones, boards or pieces of wood with bare hands outdoors or reach into spaces they cannot see. Sturdy shoes, long trousers and watching the next step reduce the risk when walking through scrub, dry-stone walls and rocky grassland. Shoes left outside should be shaken out before being put on.
These precautions are not a reason to avoid natural areas. Snakes generally try to avoid people and bite mainly when surprised, cornered or touched. Calm behaviour offers better protection than frantic searching or pre-emptively killing animals around accommodation.
The reliable interim position
What is confirmed is the reported bite, treatment with antivenom at KBC Rijeka and the four-year-old's stable condition on 23 August. The campsite, exact location, any official investigation of the grounds and any further medical update after that date have not been published.
The practical consequence for holidaymakers is clear and enduring: do not wait and see or attempt home treatment after a possible venomous-snake bite; report it as an emergency. Keeping calm, immobilising the limb and arranging rapid professional transport are correct. Cutting, sucking, tying off, cooling and catching the snake are wrong.
