How long does angina just won't infect?

summary

Pharyngitis is an acute inflammation in the pharyngeal region, which is a special type of pharyngitis. Pharyngeal isthmus is a ring structure in the vertical plane of pharynx. The upper part is the free edge of uvula and bilateral soft palate, the lower part is the root of tongue, and the left and right sides are palatoglossal arch and palatopharyngeal arch. These four sides constitute a narrow ring, which is called pharyngeal isthmus. Angina can be caused by bacteria, viruses and other bacteria, manifested as sore throat, dry throat, foreign body sensation, herpes, ulcers, and other symptoms similar to acute tonsillitis. Angina symptoms? Let's talk about it

How long does angina just won't infect?

Because the onset time of angina is generally about 1 week, if the patient is cured, angina will also lose its infectivity, but if the patient's immunity is relatively poor, the disease lasts for a long time, it may also lead to recovery after 2 weeks. Therefore, pharyngitis is generally not infectious in 1 ~ 2 weeks.

Herpangina is usually cured in about 7 days, so if it is cured herpangina patients, the virus has entered the decline period, not infectious. However, some patients are not cured after 7 days of illness, so the infected enterovirus is still infectious. Therefore, whether herpangina is infectious is not determined by time, but by whether the patient is cured. Therefore, when children's symptoms such as fever, oral ulcer, drooling and sore throat disappear, the infection rate of herpangina will increase, It can be basically judged that herpangina has been cured.

Herpangina belongs to viral infection. From the incubation period of herpangina, enterovirus begins to replicate in large quantities, and the viral replication stage is also the most infectious stage. With the development of the disease, herpangina gradually enters the onset and recovery period, and the infected enterovirus also enters the decline period.
