Chigger Bites: What You Need to Know
Chigger bites, also known as tungiasis, are caused by tiny larvae of mites that burrow into the skin, leading to irritation and discomfort. This condition is common in tropical and subtropical regions, especially in areas with tall grass and vegetation.
Cause of Chigger Bites
Chigger Larvae
These tiny larvae attach to the skin, particularly in areas where clothing fits tightly, and feed on skin cells, causing an inflammatory reaction.
Feeding Habits
Chiggers do not burrow deep into the skin but create a feeding tube called a stylostome, which they use to extract fluids from the skin.
Infestation
They can be found in tall grasses, wooded areas, and other outdoor settings where they await a host to attach to.
Symptoms of Chigger Bites
1
Intense Itching
The most prominent symptom, often appearing within a few hours to days after the bite.
2
Red, Raised Bumps
Small, swollen lesions may develop at the bite site, often resembling a small red dot or a raised bump.
3
Possible Secondary Infections
Scratching can lead to infections due to bacteria entering the skin, increasing discomfort and prolonging healing.
4
Other Symptoms
In some cases, blisters, pus-filled sores, or a rash can develop around the bite area.
Treatment Options for Chigger Bites
Topical Corticosteroids
Creams or ointments containing hydrocortisone can reduce itching and inflammation.
Antihistamines
Oral antihistamines can help alleviate itching and may be recommended if itching is severe.
Antibiotics
If a secondary infection occurs, topical or oral antibiotics may be prescribed to treat the infection.
