Yes, I believe that this would require immediate medical attention. Insect bites have the tendency to become
infected (secondary bacterial infection) and if not treated, the infection may get worse and may involve
larger areas of skin and subcutaneous tissues (this is called cellulitis, and is serious once larger areas of
skin becomes involved).
A course of antibiotics may be needed, as well as shots of anti-tetanus vaccines or immunoglobulins.
Regards and God bless.
