Stay in Brazil, surrounding people often get abscess that ooze later. How can I prevent my family from contracting it?
Thanks for writing to us.
From the description it seems you are talking about cutaneous leishmaniasis which is endemic in Brazil. It is characterised by red skin rashes which become indurated and then ulcerate eventually to heal with scar formation.
Leishmaniasis is a parasite infestation caused by sandfly bite.
No drugs or vaccines are available to prevent the same. These measures are usually advised to prevent the same
Avoid outdoor activity after dusk to prevent sandfly bite
Wear protective clothing. Wear full sleeved clothes
Use mosquito nets with very thin mesh.
Apply insect repellents over exposed body parts
Treat your home with pyrethroid based insecticides.
As it is endemic in brazil, a consultation with local doctor would give a better insight of disease and modes of prevention available over there.
Hope that helped. Should there be any other query, please write back.
Thanks for writing back.
Before I go further with this discussion, I would like you to know that the diagnosis suggested is based on the description provided and the endemicity of the same in Brazil. However the diagnosis can only be confirmed with proper tests and clinical examination.
Now to clear your doubts
Multiple bites are not required to cause multiple tumours. The causative agent of this disease is a Protozoa which infests sand fly. So when sand fly bites, this Protozoa gets transferred to human body and presents as number of cutaneous ( skin) lesions.
Sand flies are too small, so it is not necessary that you will catch a sandfly in action! In fact most of the times these mostly escape notice.
Now as your nephew and daughter both had similar lesions. I would advise that you consult a local doctor to get the lesions examined, so that a proper diagnosis is made and appropriate treatment be suggested. Leishmaniasis needs a proper cure.
Hope that helped. Take care
Thanks for writing back.
As dermatology is completely a visual field, I would really appreciate if you could attach an image of concerned lesions so that I can help you in a better way. The possibility of leishmaniasis was only suggested based on description provided.
Hoping to hear from you soon.
