Which finding suggests cellulitis or a more aggressive infection requiring medical attention?

Red streaks extending up an arm or leg toward the body center

Constant monitoring for secondary bacterial infection is necessary following any coral injury, as this is a frequent complication. Several signs indicate that the infection may be progressing into something more serious, such as cellulitis, demanding immediate medical consultation. These red flags include any spreading redness of the skin immediately surrounding the original wound site. More alarming signs are the appearance of red streaks extending centrally up an affected limb (indicating lymphangitis), the draining of pus, or the development of a thick crust over the wound. Systemic symptoms like fever, chills, or severe fatigue also signal that the infection is becoming aggressive and requires professional intervention, potentially involving intravenous or oral antibiotics.
