There are a lot of different diseases around the world. Some are highly infectious and some are very deadly. There are a lot of different kinds of diseases. In this essay, I will be talking about four different infectious diseases.
The first disease I will be talking about is the Influenza, or the flu. The flu is a type of disease that is caused by a virus. Symptoms include a sore throat, runny nose, congestion, and cough. Flu includes fever, headaches, and muscle soreness. The first sign of the Flu is often a sudden fever, aches or pains, weakness or loss of appetite. In particular, having a cough and a fever together can be a good indication that you have the Flu.
The second infectious disease I will be talking about is strep throat. Strep throat is a bacterial infection that can make your throat feel sore and scratchy. If untreated, strep throat can cause complications such as kidney inflammation or rheumatic fever. The first sign of a strep throat is a sore throat that usually starts quickly and can cause pain when swallowing, a fever, red and swollen tonsils, and sometimes has white patches or streaks of pus.
The third infectious disease is the stomach flu. The stomach flu is caused by a virus, but not the flu virus, so it’s not actually a flu. Bacteria and parasites also can cause it. Stomach flu can causes diarrhea, nausea, and possibly vomiting. You may also have headaches, fevers, chills and pain in your stomach. The one that is caused by a virus makes you feel sick 12 to 48 hours after you are exposed to it, and it can last up to three days. If it is caused by bacteria or parasites, it may last longer. It can be dangerous for people who have other health conditions and with babies or older people.
The last one I will be talking about is cellulitis. Cellulitis is caused by bacteria that enters your body through a cut or crack in the skin. Cellulitis is caused by Staphylococcus and Streptococcus bacteria. Skin injuries such as cuts, insect bites, or surgical incisions are commonly the sites of infection. You may feel pain in skin, warmness in skin, blisters, red rashes, or swelling. You can also have chills, fever, or malaise. Most people have pus; this is very common. In most cases, the skin on your lower legs is affected, although the infection may occur anywhere on your body or face. This disease affects the surface of your skin, but it may also affect the underlying tissues. Cellulitis can also spread to your lymph nodes and bloodstream.
