The most frequent way to acquire lice is through direct contact between heads, as the lice move by transferring from one person’s scalp to another’s by moving along the hair strands. Lice cannot fly or jump, but they can crawl on objects that touch the human head, such as hats, towels, brushes, or pillows. Only the body louse is known to spread the disease.
The main mode of spread for pubic lice is through intimate sexual contact between individuals.
It is important to note that dogs, cats, and other pets do not contribute to the transmission of pubic lice among humans.
What are the symptoms of Lice infestation?
Symptoms of Head lice
The presence of head lice can cause a strong urge to scratch or rub the scalp due to the uncomfortable sensation it creates.
Repetitive scratching can result in skin inflammation and reddening, particularly in the areas of the scalp and the back of the neck.
Body licesymptoms
Infestations of body lice often cause intense pruritus, which is an unpleasant sensation in the skin that causes an urge to scratch.
The allergic response can manifest as small raised marks resembling welts, along with potential redness and swelling.
Fatigue and other general symptoms may also be present.
What are the complications arise due to Lice infestation?
When the skin’s integrity is compromised, it can result in a higher susceptibility to secondary bacterial infections such as impetigo.
Skin conditions like cuts, wounds, or excessive scratching from infestations or itching can create openings in the skin that allow bacteria to enter and cause infection.
Lice, particularly body lice, can act as vectors for transmitting certain diseases to humans. These diseases include the following:
Relapsing fever is caused by various species of the Borrelia bacteria and is characterized by recurring episodes of high fever, chills, and body aches.
How to prevent strategies against Lice infestation?
Educate children to avoid head-to-head contact at school and other settings.
Immerse combs and brushes that have been used by someone with head lice in hot water for a duration of 5 to 10 minutes.
Avoid contact with furniture, cushions, bedding, or rugs that have recently been in contact with a person who has lice.
Ensure a comprehensive vacuuming of the floor and furniture, paying particular attention to the areas where the infested individual has spent time.
