Infections
Chest infections
Unless you live in a bubble, infections are part of daily life and the occasional fever or flu is something you'll get over without too much trouble. However, they're very much at the low end of the infection scale. There are a host of headline-making conditions out there such as sepsis or tuberculosis that could result in a prolonged stay in hospital.
Chest infections
Chest and lung infections (often called lower respiratory tract infections) occur when viruses, bacteria, or fungi invade your airways or lung tissue. The most common types are bronchitis and pneumonia.
Childhood infections
Infections are a normal part of childhood and help develop the immune system, with most children getting 6 to 8 respiratory or stomach infections a year. While most are viral and resolve with rest and fluids, you should monitor for high fever, lethargy, or dehydration.

ENT infections
Ear, nose, and throat infections are common and usually mild. Learn what causes them, how to treat them, and when they might need medical attention.
Fungal infections
Fungal infections can affect skin, nails, and lungs. Learn about common types, symptoms, and simple treatments that help clear them up.
Gastrointestinal infections
Gastrointestinal infections can be caused by viruses, bacteria, and parasites. Most cases clear up in a few days, but high fever, vomiting, or bloody stool need medical attention and preventing dehydration is essential.
Medicines for infections
Antibiotics and antifungals are used to treat infections. Learn when these medications are needed and how to take them safely and effectively.
Meningitis and sepsis
Meningitis (inflammation around the brain/spine) and sepsis (blood poisoning) are life-threatening medical emergencies. Immediate medical attention is vital.
