Respiratory syncytial virus (RSV) infects the lungs and breathing passages and is the leading cause of
pneumonia in young children. It is also a common cause of bronchiolitis, which is an inflammation of
the small airways in the lungs. RSV usually goes away on its own, but some children may need to be
hospitalized if they have difficulty breathing.

Pneumonia is a serious lung infection that can be caused by bacteria, viruses, or fungi. Pneumonia
can cause fever, coughing, and difficulty breathing. Pneumonia can be dangerous, especially for
young children, so it’s important to see a doctor if your child has any symptoms.
6.Meningitis
Meningitis is an inflammation of the membranes that surround the brain and spinal cord. Meningitis

Sinusitis is the technical term for a sinus infection. It is caused by a build-up of fluid in the

the face, post-nasal drip (mucus dripping into the throat), sore throat, cough, and bad
breath

and adults can get it. Symptoms include skin rash, fever, mouth sores, and flu-like symptoms
10.Gastroenteritis
Gastroenteritis is also known as the stomach flu, but it is not the flu at all. But like the flu, it is caused
by a virus that can spread quickly. Symptoms include nausea, vomiting, and diarrhea. Usually, the
symptoms pass within a couple of days and treatment includes rest and giving fluids to avoid
dehydration due to vomiting and diarrhea.
11. Ulcerative Colitis
Ulcerative colitis is a chronic inflammatory condition that affects the colon (large intestine) and
