An unexplained rash resembling bite or sting marks has plagued beachgoers in Clovelly and other Sydney beaches this summer.
Despite extensive investigation, experts remain baffled as to the cause of the skin condition, sparking concern among locals.
In recent weeks, numerous locals, particularly those frequenting beaches like Clovelly, have reported developing peculiar rashes on their skin after swimming. The rash patterns vary from red blotches to tiny raised bumps, prompting speculation about potential causes and raising questions about the safety of popular beach spots.
On a recent Sunday in February 2024, a swimmer emerged from Clovelly Beach with red blotches covering her legs and feet, joining the ranks of those affected by this mysterious phenomenon. Despite her lack of discomfort whilst in the water, the appearance of these blotches has left her and others bewildered.
Whilst some experts suggest sand flies, a type of biting midge, as the likely culprits behind these rashes, others remain unconvinced. The Queensland Museum, reviewing images of the affected individuals, admitted uncertainty about the cause but also leaned towards sand flies due to their typical delayed reaction, causing localized hive responses.
Sand flies or biting midges, known for their tiny size and inconspicuous nature, pose challenges in detection but are widespread across Australia. However, the localised nature of the bites raises doubts among experts, leading to speculation about the involvement of crustaceans such as scavenging amphipods or isopods.
Conclusive evidence remains elusive thus the true cause of the rashes remains shrouded in uncertainty.
According to the Australian Environmental Health Guide, biting midges will not transmit diseases to humans but it can cause painful and irritating bites. The severity of reactions varies, with some individuals experiencing red swollen bites measuring several centimetres in diameter.
Symptoms may include pain, itching, blistering, and weepiness, lasting for days or weeks. Desensitisation may occur in individuals continuously exposed to midges, whilst tourists or others may suffer severe reactions requiring medical attention.
