The body louse, also called cootie, is a parasite that lives on the human body. These infections are spread through person-to-person contact, poor personal hygiene, and people living in crowded conditions.
symptoms, are –
1. Body Lice
These infections are spread through person-to-person contact, poor personal hygiene, and people living in crowded conditions.
Symptoms – Intense itching, rashes, red bumps on the skin, darkened or thickened skin (especially near the groin or waist)
2. Scabies
It is one of the major skin diseases caused by poor personal hygiene. It occurs when someone comes in close contact with a person having scabies mites or when people live in crowded unhygienic conditions.
Symptoms – Itching (at night), rashes, sores and thick bumps on the skin.
3. Trachoma
The bacterium, Chlamydia trachomatis, causes trachoma. It occurs due to poor hygiene or close personal contact. It is a common public health problem that causes visual impairment or blindness in the worst cases.
Symptoms – Mild itching in the eyelids and eyes, continuous eye discharge, eyelid swelling, photophobia, eye pain, eye redness and vision loss.
4. Lymphatic Filariasis
It is a neglected tropical disease (NTD). Infected mosquito bites spread it. Microscopic thread-like worms that reside in the human lymph system cause this disease. This is an extremely rare disease that needs medical diagnosis.
Symptoms – Inflammation, lymphedema, hydrocele and oedema.
5. Head Lice
The most typical sign of head lice is itching on the scalp. This allergic reaction to head louse bites causes itching and an itchy feeling brought on by hair movement. As a result, sleeping becomes agitated and uncomfortable.
Symptoms: Itching, nicks in the hair, tickling in the scalp.
6. Staph Infections
Staph bacteria infections can present with various symptoms, such as swelling, redness, and pain. If the infection is on the skin, it may manifest as a boil or pimple. If it happens on a bone, it might result in discomfort, swelling, and redness in the affected area.
Symptoms: Food poisoning, fever, diarrhoea, vomiting, and nausea.
7. Candidiasis
The yeast Candida albicans is the source of the fungal infection called candidiasis. It is usually found on the skin or in the mouth, throat, gut, and vagina. Before treatment, if the illness spreads throughout the body, it results in fatal heart, brain, kidney, or circulation infections.
Symptoms: White patches on the skin look like peeling or crusting in the genital areas.
8. Athlete's Foot
Athlete's foot is a fungal infection that usually starts between the toes from sweating from wearing shoes that are too small. The affected area results in a scaly, itchy rash that frequently leads to peeling skin.
Symptoms: White-coloured rash in between toes, itching, scaling.
9. Ringworm
Ringworm is a rash that appears as an itchy, circular ring on the arms, legs, torso, and buttocks. On white skin, the colour changes to red; on black and brown skin, it changes to reddish, purplish, brown, or grey.
Symptoms: Red rashes, itching, scaling.
10. Giardiasis
Giardiasis is a self-limiting infection of the intestine caused by Giardia lamblia. It spreads most easily through poor hygiene practices or contaminated water intake, and it is common in places with poor sanitation.
Symptoms: Diarrhoea, abdominal cramps, nausea, vomiting, weight loss.
11. Pinworm Infection
These are small intestinal parasites transmitted through poor hygiene practices, such as not washing hands properly after passing stool. You can also contact them if you come in contact with open stools.
Symptoms: Itching at the anus, irritability, difficulty sleeping, visible worms in stool or around the anus area.
12. Impetigo
Impetigo mainly affects infants and children. Impetigo is a highly contagious bacterial infection of the skin caused by poor hygiene, such as infrequent hand washing or touching infected sores.
Symptoms: Rapid development of red sores that rupture quickly, followed by oozing that forms a yellow-brown crust; itching; swollen lymph nodes.
13. Pubic Lice (Crabs)
Pubic lice are parasitic insects that occur in coarse hair of genital areas; however, sometimes, they can also be seen in other body hair. Poor hygiene and close contact pass these lice on.
Symptoms: Itching in the pubic area, visible lice or eggs in the hair, and secondary bacterial infections due to scratching.
