Infections
Occur when pathogens invade the body and cause disease •can be local or systemic
Infections are caused by microorganisms such as bacteria, viruses, fungi, and parasites. These microorganisms enter the body through various means such as contaminated food or water, animal bites, sexual contact, or through the air we breathe.
Infections can vary in severity from mild to life-threatening, and symptoms may include fever, fatigue, inflammation or swelling, pain, and redness or discharge from affected areas.
Prevention of infections can be achieved through proper hygiene practices such as hand washing, covering the mouth when coughing or sneezing, and avoiding contact with infected individuals or contaminated materials. Vaccinations are also a highly effective way to prevent certain infections.
Treatment of infections often involves the use of antibiotics, antiviral drugs, or antifungal medications depending on the specific type of infection and its severity. In some cases, treating the symptoms of the infection such as reducing fever or managing pain may be necessary.
It is important to seek medical attention if symptoms of an infection persist or worsen, as untreated infections can lead to complications such as organ damage, sepsis, or in severe cases, even death.
