Lice Transmission
Lice Transmission
Lice spread primarily through prolonged, close physical contact. Items like hats and clothing can carry lice, but spreading this way is less common.

Study Notes
Lice Transmission
- Lice do not typically spread rapidly.
- Transmission relies heavily on close physical contact, often prolonged contact.
- Infectious period is linked to the presence of the lice on the host.
- Secondary spread, through items like hats, combs, or clothing, though possible, is significantly less common compared to direct contact.
- Infestations don't automatically propagate wildly throughout a population.
- Spread is primarily limited by the necessity for direct head-to-head contact, making large-scale outbreaks less likely.
- Individual hygiene practices and limiting the frequency of close contact are key preventive measures.
- High-density environments or close-quarters living situations may see increases in the possibility of transmission.
- However, even in such settings, large-scale outbreaks don't typically occur without other enabling factors.
- Rapid transmission is not the norm for lice infestations.
