What About Mrsa Infections
MRSA stands for methicillin-resistant Staphylococcus aureus. It is a form of Staphylococcus aureus or “staph” bacteria that is resistant to certain antibiotics. It is transmitted by directly contacting an infected person, touching contaminated surfaces, or sharing personal items that have been in contact with infected skin. MRSA is a large problem in hospitals or health care facilities . MRSA also can infect people in the community, however, such as children at day care centers and children who are involved in sports that involve close contact. This is known as community-associated MRSA or CA-MRSA.
MRSA infections can appear like a pimple or boil, with redness, swelling, pain, or pus. Serious infections may spread into the blood and cause blood infections. If you experience a MRSA infection, your doctor may drain the infected area and prescribe antibiotics such as linezolid, clindamycin, or doxycycline. Do not try to drain the wound yourself! This can worsen the infection or spread it to others.
To prevent the spread of MRSA, here are some helpful tips:
- Cover your wound with clean, dry bandages until the affected area is completely healed.
- Maintain good hand hygieneyou and those in close contact with you should wash hands frequently with soap and water.
- Do not share personal items, such as linens and clothing, with others.

It can resemble eczema. Bedbugs cause a series of eruptions where they pierce the skin.

Causes And Risk Factors
In general, rashes are caused by skin inflammation which in turn can have many causes. One of the most common forms of a rash is contact dermatitis, which occurs when a substance of some sort irritates the skin. Contact dermatitis may cause mild redness of the skin or a rash of small red bumps. A more severe reaction may cause swelling, redness and larger blisters.
Common causes of contact dermatitis and its resulting rash include:
- Poison ivy or poison oak
- Soaps, detergents, shampoos, deodorants, perfumes and lotions, especially ones with danger synthetic scents
- Household chemicals like bleach
- Prolonged exposure to heat
- Prolonged exposure to moisture
- An allergy to a medication
- A side effect or photosensitivity to a medication
When it comes to rash risk factors, having a viral, bacterial, fungal or parasitic infection all put you at greater risk for developing a rash. Also, a family or personal history of allergies or asthma raises your rash risk. Since rashes are commonly the result of contact with poison ivy, poison sumac, and poison oak or from insect bites then its not surprising that people who spend more time outdoors have a higher risk of developing a rash.
Now that weve talked so much about the various rash types, causes and risk factors, lets get to the solution sections: how to get rid of a rash.
What Is The Treatment For A Rash
Most rashes are not dangerous. Many rashes last a while and get better on their own. It is therefore not unreasonable to treat symptoms like itchy and/or dry skin for a few days to see whether the condition gets milder and goes away.
Nonprescription remedies include the following:
- Anti-itch creams containing 1% hydrocortisone cream can be effective
- Oral antihistamines like diphenhydramine and hydroxyzine can be helpful in controlling the itching.
- Moisturizing lotions
- Fungal infections are best treated with topical antifungal medications that contain clotrimazole , miconazole , or terbinafine .
If these measures do not help, or if the rash persists or becomes more widespread, a consultation with a general physician or dermatologist is advisable.
There are many, many other types of rashes that we have not covered in this article. So, it is especially important, if you have any questions about the cause or medical treatment of a rash, to contact your doctor. This article, as the title indicates, is just an introduction to common skin rashes.

Are Antibiotics Effective For A Cold Flu Or Covid
Antibiotics are used to kill bacterial infections they are not effective against viral infections, such as a cold, the flu, COVID. They also do not work against fungal infections, like ringworm or vaginal yeast infections.
You should avoid demanding an antibiotic from your healthcare provider when you have a viral infection as it will not cure your infection and might make it worse. In addition, this adds to the problem of antibiotic resistance, and it costs you money you do not need to spend. Your doctor can offer symptomatic treatment to ease your viral infection, or prescribe specific anti-viral medications if appropriate.
If you eventually need an antibiotic because of a secondary bacterial infection that might occur later, your doctor will prescribe it then.
