rabbit ringworm (dermatophytosis) in Singapore

updated 13 May 2026 by xavier fok

ringworm isn’t a worm. it’s a fungal infection of the skin. in rabbits, it causes circular patches of fur loss with scaly skin. it’s contagious to other rabbits and to humans (zoonotic).

SG humidity favours fungal growth. ringworm is regional concern.

the appearance

what to look for:

early stage

circular patch of fur loss
1-3 cm diameter typically
scaly skin underneath
mild redness

established

multiple patches possible
skin thickening
crusts and scabs
mild itching (sometimes)

locations

face
ears
paws
back commonly

the cause

fungal organisms:

Trichophyton mentagrophytes (most common)
Microsporum canis (secondary)
environmental spores

these survive in environment for months.

the transmission

how it spreads:

direct rabbit-to-rabbit contact
contaminated bedding, toys, brushes
environmental contamination
to humans (zoonotic)
to other pets (cats, dogs)

the diagnosis

vet approach:

visual examination
Wood’s lamp (UV light) — some species fluoresce
fungal culture (definitive, 1-3 weeks)
skin scraping examination

the treatment

multi-pronged:

topical antifungal

miconazole cream
enilconazole rinse
daily application
4-6 weeks

systemic antifungal

itraconazole
griseofulvin
prescribed by vet
4-8 weeks

environmental decontamination

bleach solution on hard surfaces
discard contaminated soft items
thorough cleaning weekly

the SG vet protocol

what to expect:

confirmed diagnosis (Wood’s lamp + culture)
treatment plan
isolation recommendation
environmental cleaning guidance
treat all in-contact pets

the zoonotic concern

humans can catch it:

symptoms in humans

circular red rash
itchy
spreads if not treated
common locations: arms, neck, scalp

precautions

gloves when handling sick rabbit
wash hands thoroughly
monitor own skin
see GP if rashes appear
children especially susceptible

family safety

separate rabbit during treatment
household-wide attention

the cost reality

treatment:

diagnosis (culture): SGD 100-200
topical medication: SGD 30-60
systemic medication: SGD 80-200
recheck visits: SGD 60-100 each
total typical: SGD 300-600

the SG-specific notes

three things relevant:

1. humidity helps fungus

SG climate favourable
ventilation reduces risk
AC environment less hospitable

2. multi-pet households

cats and dogs can catch and transmit
treat all suspected
environmental clean essential

3. shelter rabbits

ringworm sometimes present in shelter
screen new acquisitions
quarantine 2-4 weeks before introducing

the home isolation

during treatment:

separate room for affected rabbit
own bedding, food bowls
glove handling
minimise contact
shower after handling

the environment cleaning

protocols:

daily

enclosure surfaces wiped
food and water bowls cleaned

weekly

thorough cleaning with diluted bleach (1:32)
ventilate well after
replace soft items if possible

post-recovery

complete deep clean
discard hard-to-disinfect items
some recommend new items

the senior rabbit consideration

seniors:

weakened immune system
longer recovery
more aggressive treatment
monitor for spread

the multi-rabbit consideration

bonded pairs:

treat both
isolate together
environment shared
bond preserved

the differential

similar appearance:

mites: our diagnosis via skin scrape
bald patches: our bald patches guide
treponema: our syphilis guide
vet differentiates

the prevention

practical:

quarantine new rabbits (2-4 weeks)
avoid contact with unknown rabbits
clean environment regularly
monitor skin condition

what owners often get wrong

three patterns:

using human antifungal cream without vet. wrong dosage, irritation
not treating environment. reinfection guaranteed
assuming healed when fur returns. culture-clear required, treat longer

bald patches causes — differential
skin yeast Malassezia — another skin issue
syphilis treponema — different infection
introducing new rabbit — quarantine
