Is Second Time dengue curable?
“There are four different serotypes (which can be understood as “types”) of dengue. So, if you were to get infected by the first serotype, it is equally possible for you to get infected by the second, third and fourth. It’s just that you will be immune for life against the first serotype.”
When should you go to hospital for dengue?
Most cases of dengue fever go away within a week or two and won’t cause any lasting problems. If someone has severe symptoms of the disease, or if symptoms get worse in the first day or two after the fever goes away, seek immediate medical care. This could be an indication of DHF, which is a medical emergency.
