Summary
Snakebites in Hong Kong children are rare but can cause significant illness. A small snake bite may lead to envenomation, while a large snake bite may not, highlighting the unpredictable nature of snake venom.
Area of Science:
- Toxicology
- Herpetology
- Pediatric Emergency Medicine
Background:
- Snakebites in children and adolescents are infrequent in Hong Kong.
- While rarely fatal, snakebites can lead to considerable morbidity and public fear.
Observation:
- Two cases illustrate that snakebite severity is not correlated with snake size.
- A child experienced envenomation after a second bite from a small green snake, requiring intensive care and antivenom.
- An adolescent sustained only minor soft tissue injury from a large python bite.
Findings:
- Snakebite morbidity spectrum is independent of snake size.
- Sequential bites from snakes can occur, with envenomation potentially happening on subsequent bites.
- Small snakes can be venomous, and large snakes may not always deliver venom.
Implications:
- Public awareness is needed regarding the potential for envenomation from smaller snakes and sequential bites.
- Risk mitigation strategies, including avoiding snake habitats during peak activity times and wearing protective gear, are crucial.

01:28Rabies
Rabies is a lethal zoonotic disease caused by a single-stranded, negative-sense RNA virus of the Lyssavirus genus, within the family Rhabdoviridae. Its primary mode of transmission to humans is through bites or saliva-contaminated scratches from infected mammals such as dogs, bats, raccoons, or foxes. Transmission can also occur if infectious saliva contacts abraded skin or intact mucous membranes, including the conjunctiva.Viral Entry and Early ReplicationOnce introduced at the bite or scratch...
01:46Types of Selection
Natural selection influences the frequencies of particular alleles and phenotypes within populations in several different ways. Primarily, natural selection can be directional, stabilizing, or disruptive. Directional selection favors one extreme trait and shifts the population towards that phenotype while selecting against individuals displaying alternate traits. Stabilizing selection favors an intermediate trait with a narrow range of variation. Deviation from the optimal phenotype towards an...
