The manual should be used in conjunction with the training provided in a Collaborating Centre or Regional Laboratory and contact with that centre should be maintained in order to provide quality assurance and frequent updates of methods. For some of the techniques described, a single method is provided, indicating general consensus among the network of rotavirus laboratories. Where multiple methods
