There are two types of meningitis: Viral and Bacteria. There are different causes as to why they are caused. Viral meningitis is caused due to several viruses. Viral meningitis could take a long time to leave the body and is not curable through antibiotics. These viruses cause viral meningitis usually during summer or around fall. It is not very serious or damaging. Bacterial meningitis, on the other hand, is caused by bacteria. There are different types of bacteria which affect children and adults. Bacterial meningitis is treated with antibiotics and it is important that they be treated in time to avoid the risk of brain damage. You should consult your physician to know about the right vaccinations to prevent meningitis in children, adults or even military officers who live in dorms.
