Thank you for your query on Healthcare Magic,
These are looking like pustules developed because of secondarily infected mosquito bite lesions.
If the lesions are big with pus filled they need deroofing of the lesions under sterile conditions for pus dicharge and topical antibiotic
If they are small, they just need topical antibacterial cream application thrice daily for 5 days.
So consult your doctor for examination and drug advise.
Hope I have answered your query.
