There are different types of infectious diseases, and their symptoms may vary but in general they make you feel sick and trigger a nauseating feeling.
Infectious Disease Types
Hepatitis
Hepatitis, a viral infection refers to a condition in which the liver gets inflamed. Skin discoloration (yellow) and dark urine are some of the most common symptoms of hepatitis. Treating hepatitis at the earliest is necessary. This is because, if hepatitis B or C left untreated can cause irreversible liver damage.
Pneumonia
Pneumonia is nothing but the infection of the lungs. The disease is typically marked by inflammation of the lungs and is often the result of bacterial or viral infection. People who have contracted this infection often complain about breathing problems and chest pain. Blood tests and chest X-rays are the diagnostic tools used to confirm the presence of pneumonia. In rare cases, seasonal flu or common cold aggravate and cause pneumonia.
Tuberculosis (TB)
TB is typically marked by frequent episodes of coughing. Tuberculosis is basically a bacterial infection of the lungs and symptoms are usually noticed when the disease reaches the advanced stage. Being an airborne infection, it can affect anyone, irrespective of age. As the disease progresses, cough worsens and produces blood. This bad cough usually persists for more than 3 weeks and causes chest pain.
Oral Thrush
Oral thrush is classified as a fungal infection. This condition is the result of overgrowth of fungus in the lining of the mouth. Oral thrush triggers an uncomfortable feeling inside the mouth. This happens because white lesions develop on the tongue and in severe cases these open wounds are also seen on the gums and the tonsils. Oral thrush is frequently diagnosed in infants but in most cases, it is a minor issue. However, to reduce the pain around the mouth the doctor may prescribe some antifungal infections.
Malaria
Malaria is classified as a parasitic infection. The parasite enters our body through mosquito bites. In other words, the mode of transmission of the infection is through contact with the mosquito. A person affected with malaria typically experiences high fever and excessive sweating.
Dengue Fever
This is a viral infection caused by mosquito bites. The mosquito Aedes aegypti acts as the virus carrier and when it bites, the virus gets transmitted into the body. The viral infection causes a sudden increase in body temperature that usually ranges between 104-105 degree Fahrenheit. Other than high fever, the patient may also show red rash on many areas of the skin.
Cholera
Cholera is categorized as a bacterial infectious disease that affects the intestines. In this condition, the bacterium resides in the small intestine and secretes a toxin. This eventually causes diarrhea and abdominal pain. Drinking contaminated water or eating unhygienic food is the main culprit behind cholera. Watery diarrhea caused due to cholera can make the person dehydrated. So taking fluids from time to time is necessary to prevent dehydration.
On the whole, identifying the infection is necessary before giving any medications. A bacterial infection is usually treated with antibiotics whereas people suffering from fungal infections are given antifungal medicines. In case of parasitic infections like malaria, antimalarial medications are commonly prescribed to reduce the severity of symptoms.
