1. This is a virological mystery that needs to be solved, 2. This is excellent science with biological and virological importance. 3. The National Influenza Centre routinely carried out virological testing of respiratory samples from hospitals and polyclinics. 4. Vaccination is limited chiefly to laboratory workers directly involved with the virus or its close virological cousins. 5. Right now, we are seeing people like Michael who are having less than satisfactory virological responses. 6. Cell-to-cell transmission through virological synapse in human retroviruses is also inhibited by tetherin. 7. It has also been suggested that tetherin may be involved in the structural integrity of the virological synapse. 8. But the preliminary studies indicate that such transmission is inefficient in virological terms, meaning that it spreads slowly. 9. Heterozygosity for this mutant allele also has shown to improve one's virological response to anti-retroviral treatment. 10. "The primary problem, " he says, " is no longer virological but social ."
