Staph infections have a multitude of different causes, such as: Open wounds – This is by far the biggest cause of staph infection. Any open wound, even ones as small as a paper cut, are vulnerable to being infected. Staph bacteria will enter the body through any open wound, so it is important to properly treat, disinfect, and bandage any wounds.
Common signs include redness and pain around the area of the surgical wound. A cloudy or purulent fluid may drain from the wound, indicating infection. Fever is another common symptom, which may accompany other signs such as increased warmth, swelling, or delayed healing at the surgical site. Additional symptoms may also occur, depending on the ...
Chronic ulcer symptoms usually include increasing pain, friable granulation tissue, foul odour, and wound breakdown instead of healing. [3] Symptoms tend to worsen once the wound has become infected. Venous skin ulcers that may appear on the lower leg, above the calf or on the lower ankle usually cause achy and swollen legs.
A boil, also called a furuncle, is a deep folliculitis, which is an infection of the hair follicle. It is most commonly caused by infection by the bacterium Staphylococcus aureus, resulting in a painful swollen area on the skin caused by an accumulation of pus and dead tissue. [1] Boils are therefore basically pus-filled nodules. [2]
A gunshot wound (GSW) is a penetrating injury caused by a projectile (e.g. a bullet) shot from a gun (typically a firearm). [11] [12] Damage may include bleeding, bone fractures, organ damage, wound infection, and loss of the ability to move part of the body. [2]

Sometimes a disease may be present without showing any signs or symptoms when it is known as being asymptomatic . [ 13 ]
The lymph nodes are found in proximity to unique white blood cells that engulf or metabolize pathogens (bacteria and viruses) and defective or cancerous cells, preventing infections and malignant cancer cells from spreading. [5] Infection spreads out of the wound site to enter the lymphatic system. The wound may be small or it may be an abscess ...
