Cellulitis is an inflammation of the connective tissue underlying the skin, that can be caused by a bacterial infection. Cellulitis can be caused by normal skin flora or by exogenous bacteria, and often occurs where the skin has previously been broken: cracks in the skin, cuts, burns, insect bites, surgical wounds, or sites of intravenous catheter insertion. The mainstay of therapy remains treatment with appropriate antibiotics. Skin on the face or lower legs is most commonly affected by this infection, though cellulitis can occur on any part of the body. Cellulitis may be superficial — affecting only the surface of the skin — but cellulitis may also affect the tissues underlying the skin and can spread to the lymph nodes and bloodstream. ...

The female mosquito (in almost all species) sucks the blood of mammals, including humans. Mosquito bites often swell up hours after happening, causing a red ringed white bump about a centimeter in diameter. This bump can itch for days and over-scratching the bite can cause it to bleed. Continued over-scratching can cause scars. Mosquito bites can transmit diseases, such as Malaria, Dengue and West Nile Virus, so authorities in many areas take measures to reduce mosquito populations through pesticides or more organic means. An easy way to reduce mosquito populations in a residential area is the removal of standing water (where mosquitoes breed), and the use of repellents, such as DEET. ...
