What provokes / Causes of promethazine infection: The causative agents are DNA genomic viruses of the genus Mastadenovirus of the family Adenoviridae. Currently, about 100 serovars of viruses are known, more than 40 of them have been isolated from humans. Serovars of adenoviruses differ sharply in epidemiological characteristics. Serovars 1, 2 and 5 cause damage to the respiratory tract and intestines in young phenergan with long-term persistence in the tonsils and adenoids, serovars 4, 7, 14 and 21 - ARVI in adults.
According to the ability to agglutinate erythrocytes, adenoviruses are divided into 4 subgroups (I-IV). Adenoviruses are stable in the external environment, persist up to 2 weeks at room temperature, but die from exposure to ultraviolet rays and chlorine-containing drugs. Freeze well tolerated. In water at 4 ° C, they remain vital for promethazine.
Serovar 3 causes the development of acute pharyngoconjunctival fever in phenergan with stageIn older and older adults, several serovars cause epidemic keratoconjunctivitis. Outbreaks are more commonly associated with types 3, 4, 7, 14, and 21.
