Hi..
Can understand your concern...
As per your complain
fever and rashes in an infant while cutting or eruption of first tooth can occur as a result of "TEETHING".
Fever occurs due to inflammation in the gums during the teething process while rashes occurs on the cheeks,around the mouth and other parts of body like hands and chest due to
drooling of excessive saliva and the different parts exposed to the saliva can get bacterial accumulation and rashes..
The best way to treat the fever and rashes is by giving
Acetaminophen to the infant as well as maintaining dry and clean body surfaces by persistent wiping with a sterile cotton and applying baby cream..
Try to feed the baby with more of water and liquid to maintain hydration..
Roseola or Rose rash of infants is a viral infection caused by Human
herpes virus 6 and 7 and is seen in children below 2 years of age and has a specific pattern in which there is fever for about 3 days followed by rashes occurring when the child starts recovering from fever starting from trunk and progressing to neck and face..
In this case also Acetaminophen is given to reduce fever as
antiviral drugs are not effective in curing the disease..
But in your case teething seems to be the cause for fever and rashes..
I would suggest you to consult a Paediatrician and get clinically evaluated and treatment can be planned after proper diagnosis..
Hope this information helps..
Thanks and regards..
