The course of pneumonia in infants is usually about 10 days, and can be longer or shorter depending on the causative agent and the accompanying symptoms, or the nature of the pneumonia. Common viral pneumonia usually heals in about 7-10 days. In the case of bacterial pneumonia, anti-infective treatment will mostly heal in about 10 days. If you are suffering from mycoplasma pneumonia, the course of treatment should be longer, about 2 weeks to heal, but mycoplasma infection in the case of more active treatment, more in place, the acute phase is usually better controlled in about 1 week, the remaining 1 week is basically the consolidation of treatment with drugs to achieve a full course of anti-mycoplasma infection. There are some babies with pneumonia that are not related to infection, but to their own constitution and allergies, which require active efforts to find allergens and effective isolation.
