Skin infections, common in India due to heat, humidity, and dust, arise when pathogens breach the skin barrier. Bacterial infections like pyoderma and fungal infections such as ringworm are prevalent. Early recognition of symptoms is crucial to prevent complications. Key signs include persistent redness and swelling that may spread, and warmth to the touch, indicating the immune system's fight against invaders. Red streaks can signal the infection entering the lymphatic system.
