Skin infections are a common medical condition that occurs when harmful bacteria or fungi infiltrate the skin, causing inflammation and various symptoms. Proper treatment is crucial to prevent the infection from spreading and causing further complications. Fortunately, there are several effective strategies to treat skin infections and promote healing.

  1. Topical antimicrobial agents: One of the main treatments for skin infections consists of the use of topical antimicrobial agents. These medications, available in cream or ointment form, are applied directly to the affected area to attack and eliminate infectious microorganisms. Depending on the severity of the infection, a healthcare professional may prescribe an over-the-counter antimicrobial cream or a stronger prescription ointment.
  2. Oral antibiotics: In more severe cases of skin infections, oral antibiotics may be necessary to fight the infection and promote healing. Oral antibiotics act by attacking bacteria or fungi from inside the body, inhibiting their growth and spread. It is important to follow the prescribed dosage and complete the entire antibiotic treatment to completely eradicate the infection.
  3. Wound Care: Proper wound care is vital for effective treatment of skin infection. Cleaning the affected area with mild soap and water, patting it dry, and applying an appropriate bandage can promote healing and prevent new infections. Additionally, regularly changing the bandage and keeping the wound clean and dry are essential steps in the healing process.

Skin Infection Treatment: An Overview

Topical medications: Depending on gravity and type of infection, health professionals can prescribe topical medications to apply directly in the affected area. These medications usually contain antibiotics, antifungals or antiviral agents, and help eliminate microorganisms that cause infection. It is important that patients follow the prescribed application guidelines, including the frequency and duration of use.

  • Antibiotics: topical antibiotics, such as ne o-cypirocin, are usually used to treat bacterial skin infections. They act inhibiting the growth and spread of bacteria, helping the healing process.
  • Antifungal: In cases of fungal skin infections, antifungal creams or ointments such as clotrimazole or terbinafine may be recommended. These medications help eliminate excessive fungus growth and relieve symptoms such as itching and redness.
  • Antivirals: certain skin infections caused by viruses, such as herpes simple or chickenpox, may require antiviral medications such as acyclovir or family to control viral replication and reduce the duration and severity of symptoms.

In addition to topical medications, systemic treatments may be necessary for the most serious or deep skin infections that cannot be treated effectively only with topical applications. These treatments are usually administered orally or intravenously and are designed to attack infection from inside the organism. It is important to keep in mind that systemic medications should only be prescribed and controlled by health professionals.

Oral antibiotics Bacterial skin infections Amoxicillin, cephalexin
Antifungal tablets Systemic fungal infections Fluconazole, Itraconazole
Antiviral medications Viral skin infections Valacyclovir, Famciclovir

Understanding Skin Infections

Common causes of skin infections

  • Bacterial infections: bacteria can penetrate the skin through cuts, scratches or insect bites, giving rise to infections such as cellulite or impetigo.
  • Fungal infections: fungi prosper in warm and humid environments, and usually cause skin infections such as athlete or dye.
  • Viral infections: Certain viruses, such as herpes simple herpes virus or human papillomavirus, can cause skin infections such as lip herpes or warts.

Recognize symptoms:

  1. Redness and swelling: skin infections usually cause redness and swelling located around the affected area.
  2. Itching and irritation: Persistent itching and irritation are common symptoms of skin infections, especially those caused by fungi.
  3. Pain and discomfort: Some skin infections can cause pain or discomfort, especially when pressure is applied to the affected area.
Types of skin infections Common symptoms Treatment options
Cellulitis Redness, swelling, heat, pain Oral antibiotics, rest, elevation
Athlete’s foot Itching, peeling, blisters, cracked skin Topical antifungal creams, keep feet dry
Herpes simplex Painful blisters, ulcers, tingling sensation Antiviral medications, pain relievers

It is important to note that seeking medical care for skin infections, especially if symptoms worsen or persist, is essential to obtaining an accurate diagnosis and an appropriate treatment plan.

By understanding the causes and recognizing the symptoms of various skin infections, people can take the necessary precautions and seek appropriate treatment to promote healing and prevent the spread of infections to others.

Common Types of Skin Infections

Bacterial Infections

One of the most common types of skin infections are bacterial infections. These occur when bacteria invade the skin through cuts, abrasions or other forms of skin damage. Staphylococcus and Streptococcus are the two main types of bacteria that cause skin infections. Staphylococcal infections can manifest as impetigo, cellulitis or abscesses. On the other hand, streptococcal infections usually cause erysipelas or cellulitis.

  • Impetigo: This highly contagious bacterial infection usually affects children and usually begins as red sores around the nose and mouth. These ulcers gradually burst and form scabs.
  • Cellulitis: This infection affects the deeper layers of the skin and underlying tissues. It is characterized by redness, swelling, heat and tenderness in the affected area.
  • Abscess: An abscess is a collection of pus caused by a bacterial infection. It appears as a swollen, painful lump filled with fluid.

Bacterial skin infections can be treated with antibiotics, which can be given orally or topically depending on the severity of the infection. It is important to follow the prescribed treatment regimen and complete the full course of antibiotics to ensure complete eradication of the infection.

Fungal Infections

Fungal skin infections, also known as dermatophytosis or ringworm, are caused by fungi that thrive in warm, moist environments. These infections can affect various parts of the body, such as the scalp, feet, groin, and nails.

  1. Athlete’s foot: This common fungal infection affects the feet, especially between the toes. It causes itching, redness, peeling and blisters.
  2. Jock itch: Jock itch, or tinea cruris, is a fungal infection that affects the groin area. It presents as a red, itchy rash with a well-defined border.
  3. Ringworm: Despite its name, ringworm is not caused by worms, but by a fungus. It can appear on various parts of the body, resulting in a ring-shaped rash with red, scaly edges.

Athlete’s foot Itching, redness, peeling, blisters
Jock itch Itchy red rash with a defined border
Tub Ring-shaped rash with red, scaly edges

Antifungal medications, such as topical creams or oral tablets, are commonly used in the treatment of fungal skin infections. It is important to maintain good hygiene practices and keep the affected area clean and dry to prevent further spread of infection.

Diagnosing and Treating Skin Infections


When a patient presents with symptoms of a skin infection, the first step in diagnosis is usually a complete physical examination. This exam may include evaluating the affected area for redness, swelling, warmth, and tenderness. Additionally, the patient’s medical history will be taken into account, including underlying illnesses, recent injuries or surgeries, and previous skin infections.

Common diagnostic tests for skin infections include

  • Bacterial culture: A sample can be collected from the infected area and sent to a laboratory for analysis. This test helps identify the specific bacteria causing the infection and determine the most appropriate antibiotic treatment.
  • Biopsy: In some cases, a small sample of the affected skin may be taken for biopsy. This helps rule out other skin conditions and confirm the presence of a skin infection.


Treatment of skin infections depends on the type and severity of the infection. Mild infections are usually treated with topical antibiotics or antifungal creams. However, more serious infections may require oral antibiotics or antifungal medications. To prevent the reappearance or development of antibiotic-resistant bacterial strains, it is essential to complete treatment with the prescribed medication, even if symptoms improve.

Prevention and monitoring:

  1. Good hygiene practices, such as regular hand washing, can help reduce the risk of skin infections.
  2. Avoiding close contact with people who have known skin infections can also minimize the chances of transmission.
  3. Follo w-up quotes with health professionals are important to control the evolution of treatment and guarantee the complete resolution of the infection.

Antibiotic Therapy for Skin Infections

1. Staphylococcal infections: Staphylococcus aureus is a common bacterium that can cause various skin infections, from minor folliculitis to more serious conditions such as cellulite or abscesses. The treatment of staphylococcal infections usually consists in the use of antibiotics such as sewth, dicloxacillin or cephalexin. These medications are usually effective against Staphylococcus aureus and help eliminate bacteria that cause infection.

  • Habitual antibiotics for staphylococcal infections:
    1. Cloxacillin
    2. Dicloxacillin
    3. Cephalexin

2. Streptococcal infections: streptococcal bacteria, particularly Streptococcus pyogenes, can also be responsible for various skin infections, such as impetigo, erisipela or necrotizing fasciitis. Antibiotic therapy is crucial to treat streptococcal infections, and among the antibiotics prescribed are usually penicillin, amoxicillin or erythromycin. These medications help eradicate bacteria and prevent infection from spreading.

It is important to note that the appropriate diagnosis and identification of the causative body are essential to determine appropriate antibiotic therapy. In some cases, oral antibiotics can be enough, while the most serious infections may require intravenous administration. It is imperative to follow the prescribed treatment course and complete the complete antibiotic course to ensure that infection is effectively and to minimize the risk of antibiotic resistance.

3. Staphylococcus aureus infections resistant to meticillin (SARM): SARM is a type of bacteria resistant to many common antibiotics, which makes infections caused by SARM more difficult to treat. To combat SARM infections, antibiotics such as clindamycin, trimetoprim-sulfamethoxazole (TMP-SMX) or doxycycline are usually used. However, the choice of antibiotics for SARM infections can vary depending on the severity and location of infection.

Habitual antibiotics for SARM infections: Route of administration
Clindamycin Oral or intravenous
Trimetopriga-sulfamethoxazole (TMP-SMX) Oral
Doxycycline Oral

In general, antibiotic therapy plays a crucial role in the treatment of skin infections caused by bacteria. However, it is important to consult a healthcare professional to obtain an accurate diagnosis and adequate antibiotic prescription, since the choice of antibiotics can vary depending on the specific infection and the individual factors of the patient.

Home Remedies and Self-Care for Skin Infections
