Bacterial colds are infections of the upper respiratory tract caused by bacteria, which have a certain ability to heal themselves and have a relatively good prognosis. Mild bacterial colds can recover slowly by drinking more water, taking more rest and eating more vegetables and fruits. However, heavy bacterial colds may take longer to heal on their own and may be complicated by other diseases such as bronchitis and laryngitis, so you should use medications such as cold and fever pellets in a timely manner. Bacterial infections often cause elevated blood counts, and antibiotics such as macrolides and cephalosporins should also be used. During the treatment period, take more rest and eat a light diet with less spicy and greasy food.
