Bacterial infections in the throat are caused by two factors: 1) a decrease in the body’s immune system, including the external invasion of wind and cold evil, as well as their own physical weakness; 2) a sudden infection caused by foreign bacteria or a small amount of pathogenic bacteria that have existed in the throat for a long time; a bacterial infection in the throat will cause a series of symptoms such as coughing, sore throat, spitting, etc., and in severe cases, it may induce systemic symptoms such as coldness, fever, and weakness. In severe cases, systemic symptoms may be induced, with a series of inflammatory manifestations such as peripheral chills, fever and malaise, which can be treated symptomatically with sensitive antibiotics.
