Otitis media, commonly known as an ear infection, occurs in the middle ear, located right behind the eardrum. It’s caused by bacteria or viruses from the nose and throat becoming trapped, leading to inflammation and fluid buildup. This condition differs from otitis externa (swimmer’s ear), which is an infection of the outer ear. To understand more about ear infections, visit Ohio State Medical Center.

Another health concern is toxoplasmosis, a disease that can be transmitted from cats to humans. Symptoms include muscle aches, fever, and headaches, with more severe cases presenting confusion, seizures, vomiting, or diarrhea. Basic hygiene, such as wearing gloves when handling potentially contaminated material, is crucial for prevention. For detailed information on toxoplasmosis, visit Cornell Feline Health Center.

Gastroenteritis, often mistaken for stomach flu, is an inflammation of the intestines caused by viruses, bacteria, or parasites.

Various viruses like adenoviruses and astroviruses can cause gastrointestinal infections, especially in children. Symptoms primarily include diarrhea, and in some cases, complications like intussusception can occur. For an in-depth look at gastrointestinal infections, visit A.T. Still University.

Vertigo, or dizziness, can occur in children with or without an eardrum problem. The inner ear’s vestibular system, responsible for balance, is often affected in these cases. Most related issues resolve after treating the underlying minor illnesses. To learn more about vertigo in children, visit Children’s Hospital of Philadelphia.

Nausea, vomiting, and diarrhea are less common symptoms of COVID-19, but can also indicate gastroenteritis or food poisoning, often caused by norovirus.
