For this summative assessment I need to write a research paper about a disease that I will choose on my own. Diseases are divided into two categories. Those categories are viral and bacterial. The disease that I chose is sore throat and it is an bacterial disease. Bacterial disease usually can be avoided by artificial immunity which includes vaccine but artificial immunity doesn’t have any effect on viral diseases. The disease that I chose is one of the most common diseases of the world, and it isn’t very harsh, this means you can’t die from it. The sore throat is painful, dry and a scratchy feeling in the throat. Each year there are reported more than 13 million visits to doctors office for this case. Sore throat is divided into three different categories. Those categories are pharyngitis, tonsillitis and laryngitis. Pharyngitis affects the area right behind the mouth. Tonsillitis is swelling and redness of the tonsils, the soft tissue in the back of the mouth. Laryngitis is swelling and redness of the voice box, or larynx. Some of the symptoms for sore throat are when your throat feels burning, raw, scratchy, irritated, tender and dry. Sore throat often happens with other diseases. This means that while you have sore throat you even have other diseases. Some of them are fever, sneezing, cough, headache, body ache, appetite loss etc. There is not only one cause for sore throat but there are a lot of them. The most common cause is getting cold and other viral infections. These viruses cause about 90% of sore throats. Allergies cause sore throats too. The immune system reacts to allergy triggers and it can cause throat irritation. Injuries can be a big factor on sore throats. Some examples of this are when you yell frequently, getting a piece of food stuck in your throat, cut or hit in the neck etc. Dry air too is one of the other reasons, it can suck moisture from the mouth and throat, and leave them feeling dry and scratchy. And the last one that I am going to explain is chemicals, smoke and other irritants. Some of the most common irritants are: cigarettes and other tobacco, cleaning products and other chemicals and air pollution. So in a way this is how sore throat is transmitted in the community. Sore throat is not one of those diseases that happens in a specific country, it can happen in any place of the world. But how does the sore throat affect your body? The viral cells will replicate and attack certain parts of the body. If your immune system can’t conquer the virus completely, then the virus may enter the bloodstream and cause the pain and soreness of your throat and other symptoms of the particular illness. Certain areas of the throat may even swell, like your tonsils, which is a sign that your immune system is still in the fight to destroy the invading cells. The most common treatment for this disease is vaccine or antibiotics so in other words artificial immunity.
