Infectious Skin Diseases

Infectious Skin Diseases

Infectious skin diseases are also known as contagious skin diseases. It means that the rash can spread from one person to another, by skin to skin contact or by touching a surface like table tops, bedding which has the germ on it. The infecting organism can be a virus, a bacteria or a fungus. It can get into skin commonly through a minor scratch or cut which damages the skin surface and destroys the barrier to infection. Described below are some common infectious skin diseases which can affect both adults and children.

Below listed are all kind of skin diseases:

Ring worm Infection (Tinea)

Ring worm Infection

Ring worm infection is a highly contagious skin disease. It has nothing to do with worms, but it is caused by a fungus. It can appear in any area of the body. The rash is red or pink with a ring like pattern, a raised border which is sometimes scaly and center of the patch clears up when the lesion increase in size. It can be associated with Athletes foot and Jock itch which are also fungal infections. Ring worm infection is a very itchy rash and scratching can lead to infection.

It is common in people who live in warm, humid climates. It can occur in people with diabetes, obese individuals and people with poor hygiene.

Management is by starting an appropriate antifungal cream. Treatment is long term (up to about 6 weeks). Usually after total clearance, continue applying at least for 1 more week as there is a chance of reappearance of the rash in a few weeks if the fungal infection is not cured properly.

Keep the rash area clean and dry.

Prevention is better than cure. Shower twice a day, if you sweat a lot and if you live in warm humid conditions. Wear clean clothes, socks and underwear daily.

Since Ring worm infection is very infectious do not share your towels or clothes with others.

Scabies

Scabies

Scabies is caused by a mite who burrows in to skin. The reaction from the skin towards the mite causes a red, papular (like bumps) rash which is intensely itchy. It is a common skin condition which is highly infectious. It is spread in overcrowded places like extended care facilities, homeless shelters and nursing homes through bedding and furniture. That doesn’t mean that people who practice good hygienic practices cannot get the infection.

Scabies can be treated easily by prescription of a scabicide (Medicine that kills the scabies mite). However adherence to the instructions during treatment is a must for cure. Medication should be applied all over the body except face (neck down up to toes).

As scabies is highly contagious, treatment should be done not only for the patient but his or her close contacts as well. Treatment is not complete unless you wash and dry your clothes, towels and bed linen as well, because the mite can survive in these and re-infest the person.

Chicken pox and Shingles

Chicken Pox

Chicken pox

Chicken pox is an infection caused by the Varicella zoster virus. Rash is itchy and painful with small fluid filled blisters (vesicles). As it is highly contagious, patient needs isolation. Chicken pox can be associated with cold symptoms and fever. When blisters are broken, scabs and crusts appear over them and usually heal within 2 weeks.

Home remedies

Calamine lotion can be applied over the rash to soothe the area. OTC Acetaminophen (Tylenol) can be taken for pain and fever and an antihistamine like Loritidine/ cetirizine/ fexofenadine or chlorpheniramine can be used to relieve symptoms of cold and itching.

Shingles

Shingles

Once Chicken pox rash is resolved, the virus stays dormant inside the body. It can reactivate during periods of low immunity such as in elderly, cancer patients, then it is called shingles. It is a very painful rash which occurs in a certain area of the body with blisters. The pain can last up to 2-3 weeks even after rash settle. That pain is referred to as post herpetic neuralgia.

Home remedies

  • Cool the rash with cold compresses
  • Apply calamine lotion to the blisters for soothing effect
  • Try an over the counter pain killer like Tylenol (acetaminophen) or ibuprofen to reduce pain.

But it is better to seek medical help especially if rash worsens and pain is unbearable.

Shingles can be prevented by giving Shingles vaccine to people over 50 years of age.
