bacterial infectious diseases

Bacterial infectious diseases are illnesses caused by harmful bacteria, tiny organisms that can invade the body and multiply. They can lead to various health issues, from mild infections like strep throat to severe diseases such as pneumonia or tuberculosis. Bacteria can spread through direct contact, air, or contaminated food and water. Symptoms often include fever, fatigue, and localized pain. Treatment typically involves antibiotics, which target and kill the bacteria. However, antibiotic resistance is a growing concern, making prevention—like vaccination and good hygiene—essential in controlling these infections.
