Infectious Diseases Causes, Signs, Symptoms, Treatments
Infectious disorders are the name that's given to disorders that are caused by organisms such as viruses, bacteria, parasites, and fungi. Many organisms can live both on and inside of our bodies, and they're normally quite harmless, or even helpful. However, in certain conditions, some organisms might prompt the onset of disease. Sometimes, infectious diseases might be passed from person to person, while in other cases, they could be transmitted through the bites of animals or insects. Other infectious diseases can be acquired by consuming contaminated water or food that have been exposed to specific organisms in the environment.
Infectious Diseases Signs and Symptoms:
The signs and symptoms of infectious diseases can vary according to the organism that's causing the infection. Usually, they include some manner of fatigue and fever. Milder infections might respond to home remedies and bed rest, while some more life-threatening infections can often require hospitalization. Each infectious disease comes with its own range of symptoms, and general signs may include:
- Muscle aches
Infectious Diseases Causes:
The causes of infectious diseases can be quite varied. Sometimes, they're caused by bacteria, single-celled organisms that are responsible for conditions like urinary tract infections, strep throat, and tuberculosis. Infectious diseases can also be caused by viruses. These organisms are much smaller than bacteria, and cause a range of dangerous diseases, ranging from the common cold, all the way to AIDs.
Infectious diseases may also be caused by fungi. Many different skin concerns, such as athlete's foot, or ringworm, are caused by fungi, and other types of fungi can build up in the nervous system or lungs. Additionally, malaria is often caused by a tiny parasite transmitted through the bite of a mosquito. Other types of parasites can be transmitted to humans from animal feces.
Infectious Diseases Treatments:
Generally, knowing what is causing your infectious disease allows your doctor to choose the right treatment. Antibiotics are a common cure for infectious diseases. Some types of bacteria are particularly susceptible to particular types of antibiotics, and treatment can be targeted when your doctor understands what you're fighting. Additionally, though antibiotics are often reserved for bacterial infections, they can sometimes be given for other concerns too, which is why the overuse of antibiotics has become a serious concern in modern medicine.
Antivirals can be used to treat some viruses. For instance, anti-viral medicine cannot be used to cure things like Influenza and Herpes. Alternatively, for infectious diseases caused by fungi, antifungals can be used to treat a range of infections. Some fungal infections, particularly those that impact the mucous membranes or lungs, can be treated using an oral antifungal. Some of the most severe internal fungal infections might require the use of intravenous medications.
Finally, one of the treatment options that can be used for certain types of infectious disease may be anti-parasitic. These treatments are used for conditions that are caused by tiny parasites, such as malaria. Though there are drugs that can help to treat these diseases, certain parasites have developed a resistance to those drugs.
