At the back of your throat, two masses of tissue called tonsils act as filters, trapping germs that could otherwise enter your airways and cause infection. They also produce antibodies to fight infection. But sometimes the tonsils themselves become infected. Bacterial and viral infections can cause tonsillitis. A common cause is Streptococcus (strep) bacteria. Tonsillitis EBV usually is caused by the Epstein-Barr virus (EBV). It is most often seen in teens and young children. Children can get the virus, but it often goes unnoticed because their symptoms are mild. Older adults usually don’t get Tonsillitis EBV, because they have better immunity to the virus.The most common symptoms of Tonsillitis EBH are high fever, a severe sore throat, swollen lymph nodes (sometimes called swollen glands) and tonsils, and weakness and fatigue.
