These NICs collect specimens in their country, perform primary virus isolation and preliminary antigenic characterization.

During an outbreak, virus isolation and electron microscopy are most often not feasible options.

This form was marked by a fever that occurred after the usual incubation period and could be confirmed only by antibody studies or, rarely, by virus isolation.

Common laboratory tests for chikungunya include RT-PCR, virus isolation, and serological tests.

Now for the next stage of the virus isolation.
