How is rotavirus disease diagnosed?
 Confirmation of a diarrheal illness such as rotavirus
requires laboratory testing

special testing with enzyme immunoassay or
polymerase chain reaction
– Such testing is not commonly available or necessary

Is there a vaccine against rotavirus?
 Currently there are 2 rotavirus vaccines:
– RotaTeqTM
– RotarixTM
 Main characteristics

– Both protect against severe forms of rotavirus disease
– Both do not protect against diarrhea caused by other agents
than rotavirus

 Our country is about to introduce RotarixTM
 Next modules of this training will explain how to:
 Store the vaccine
 Determine vaccine eligibility
 Administer the vaccine
 Record the vaccine
 Monitor adverse events following immunization (AEFIs)
 Communicate with caretakers about the vaccine
