The most common types of infections are bacterial, viral, fungal, and parasitic. Each has its own set of characteristics and symptoms.
Infections can spread through various routes, including direct contact with an infected person, airborne transmission, consumption of contaminated food or water, and vector-borne transmission through insects like mosquitoes.
Common symptoms include fever, fatigue, cough, sore throat, body aches, and inflammation. Symptoms vary depending on the type of infection.
Good hygiene practices like regular handwashing, safe food handling, avoiding close contact with sick individuals, and getting vaccinations can help prevent infections.
You should see a doctor if you have persistent high fever, severe symptoms, difficulty breathing, prolonged illness, or if you're at risk of complications due to a pre-existing condition.
No, antibiotics only work against bacterial infections. They are ineffective against viral, fungal, and parasitic infections.
Many infections can be effectively treated with appropriate medication like antibiotics for bacterial infections, antiviral drugs for viral infections, and antifungal medications for fungal infections.
Antibiotic resistance occurs when bacteria evolve and become resistant to the effects of antibiotics. This makes infections harder to treat and increases the risk of disease spread, severe illness, and death.
Yes, it's possible to have an asymptomatic infection where you carry the infectious agent but do not exhibit symptoms. However, you might still be contagious.
The immune system fights infections through a complex network of cells, tissues, and organs. It identifies and attacks foreign invaders like bacteria and viruses, often creating antibodies to protect against future infections.
