Since July 15th, the child has been suffering from a persistent cough and has been on intravenous fluids for seven days, but has not fully recovered. How long does it take for such a condition to completely recover? According to traditional Chinese medicine, this is mainly due to unintentional exposure to wind and cold in daily life and sensation. There is still no complete recovery, and medication needs to be continued. It may take 5-7 days to recover. Pay attention to staying warm, avoid cold and raw foods, which are beneficial for recovery. It is also necessary to take oral lung-moistening and expectorant medicine, give the child plenty of water, enhance their immune system, monitor body temperature, and have a follow-up medical check-up after medication ends.
