Hello and welcome to Healthcare magic.
High grade fever
and the other symptoms you describe are not suggestive of meningitis
Only thing that you should check is neck stiffness
.There will be pain in neck associated with usual fever cause.but in meningitis it will be very severe,so that the child will not be able to flex his neck.Which means that,in a sitting position, if you try to bend his head down to touch the chest,the child will scream with extreme pain.Additionally the child will look very sick and vomiting
may be present.Occassional seizures(fits) can also occur.
If you see any of these signs,rush him to the nearest Pediatrician
