The Sneaky Invader: How Pneumococcus Enters Your Body
Pneumococcus is transmitted through close contact or airborne droplets. It typically starts by colonizing the nose and throat, often without causing symptoms. However, if it manages to breach your body's defenses, it can spread to other areas, leading to infection. The bacteria's ability to adhere to human cells and form protective biofilms makes it a formidable foe.
The Bacterial Armor: Understanding Pneumococcus's Defenses
Pneumococcus has a secret weapon: its capsule. This outer layer acts like a shield, protecting the bacteria from your immune system. There are over 100 different types of capsules, which is why developing effective vaccines has been challenging. The bacteria can also change its surface proteins to adapt to different environments in your body, making it even harder to fight.

The Battle Within: Your Body's Response to Pneumococcal Infection
When pneumococcus invades, your body launches a strong inflammatory response. While this is meant to fight the infection, it can sometimes cause more harm than good. The inflammation can lead to tissue damage and the symptoms we associate with pneumococcal diseases, such as fever, cough, and difficulty breathing.
