During humid weather, skin infections are very common. Now, they do happen through the entire season, but humid weather is when you should be extra careful.

Skin infections can be contagious and have to be managed effectively and quickly. If not, you risk infecting other people, and the circle continues.

Types of skin infections

There are four types of skin infections. Causes of each type depending on the source of infection. The four types of skin infections are bacterial, viral, fungal, and parasitic. Bacterial and viral infections are hard to contract.

However, fungal infections can spread very easily and quickly. In some cases, skin infections can be caused by an injury, especially when your injury is exposed to the environment. In this case, the injury attracts germs, and they can infect your skin.

In most cases, skin infections are minor, and with the proper care and hygiene, you can take care of them in a few days. However, if the skin infection lasts more than three days, you should schedule a visit to the doctor, preferably a dermatologist to see what the problem is. In some cases, you might have to receive a more concentrated form of treatment.

Bacterial infections

You can say that bacterial infections are the most common type of skin infections. They can range from mild, to even life-threatening. Majority of bacterial infections are caused by just two types of bacteria, a variant of Streptococcus (the same bacteria causing strep throat) and Staphylococcus aureus.

In most cases, bacterial infections can be treated with home remedies, and by a general physician. Rarely, complex bacterial infections require the help of a specialist dermatologist.

Here are some common bacterial infections:

  • Cellulitis affects two deeper layers of the skin, which are the dermis and the subcutaneous tissue. Can be caused by the two main bacteria, but also other types of bacteria
  • Erysipelas is commonly referred to as St. Anthony’s Fire, because it is painful, and often accompanied by an intense burning sensation in the skin
  • Folliculitis is a common infection caused by clogging and infection of the hair follicles. You will notice tiny and red bumps filled with pus
  • Impetigo is another infection affecting the top layer, and it is also known as the epidermis. This infection is highly contagious. It happens more commonly in children than in adults
  • One of the most complex bacterial infections is Methicillin-resistant Staphylococcus aureus or MRSA. It is resistant to standard antibiotic treatment and requires special care by a dermatologist

Viral skin infections

As the name suggests, viral infections are caused by a virus. Most of the viruses causing skin infections can cause other skin conditions as well. In most cases, viral infections are mild, but can sometimes be severe.

Here are the most common ones:

  • Measles, a highly contagious infectious disease caused by the measles virus. In some cases, measles can cause an epidemic, as they spread easily between children. In addition to skin rash, symptoms include fever, cough, runny nose, and inflamed eyes
  • Chickenpox is also highly contagious. The viral infection causes an itchy rash, accompanied by small and fluid-filled blisters
  • Shingles are another infection caused by the varicella virus. Same as chickenpox, the infection causes a painful rash, and can occur anywhere on the body
  • Warts are growths on your skin caused by the HPV virus. Commonly, they appear on your fingers, but also on the soles of your feet. Genital warts are sexually transmitted disease

Fungal skin infections

Fungal skin infections usually develop in damp areas of your body. The reason is simple, wet and damp areas are a perfect breeding ground for fungus. Usually, those areas include the armpit and the feet. In most cases, fungal infections are not contagious, and they are not life-threatening.

The common fungal infections are:

  • Athlete’s foot
  • Ringworm
  • Nail fungus
  • Yeast infections
  • Oral thrush
  • Diaper rash

Parasitic skin infections

Last, but not least, we have parasitic skin infections. As the name suggests, they are caused by a parasite. They spread beyond the skin, into your bloodstream and organs. While they are not life-threatening, parasitic infections are highly uncomfortable.

The most common ones are:

  • Lice
  • Scabies
  • Bedbugs
  • Cutaneous larva migrans

Symptoms of a skin infection

As mentioned previously, depending on the type of skin infection, the symptoms can vary. But there are some general and common symptoms you will notice, like redness of the skin and rash.

Other symptoms include itching, pain, and tenderness of your skin.

If you notice pus-filled blisters, that do not improve over a period of a few days, you should visit a doctor.

Signs of severe infections include:

  • Blisters
  • Skin sloughing
  • Skin breakdown
  • Us
  • Dark, and necrotic-appearing skin
  • Skin that becomes discolored
