Scarlet fever can eat leeks. Scarlet fever is an acute infectious disease caused by hemolytic streptococcal infection. The bacterial components of the bacteria itself and the toxins and proteases it produces are involved in the pathogenic process, causing a series of septic, toxic and allergic lesions. Streptococcus bacteria mostly invade the human body from the respiratory tract, first causing pharyngobuccal inflammation and tonsillitis, and under the action of the protease it produces, the inflammation spreads and causes tissue necrosis. At the same time, due to the action of heat-causing exotoxin (rubella toxin) produced by bacteria, it can cause systemic toxemia. It can be seen that scarlet fever is a disease caused by bacteria, and there is no clear relationship with the type of food consumed, therefore suffering from scarlet fever does not affect the consumption of leeks. However, if the patient is allergic to leeks or uncomfortable after using leeks, then it is recommended not to eat leeks. The treatment of the disease should be carried out under the guidance of a physician to avoid delaying the condition, and attention should be paid to a balanced diet during the period of illness.
