TABLE 2.
ACV-resistant isolates identified in survey, by ACV treatment history and immunologic status
| Immune status | Treatment status | No. of patients | No. (%) of patients infected with resistant isolates |
|---|---|---|---|
| Immunocompetent | Untreated | 708 | 3 (0.42)a |
| Immunocompetent | ACV treatedb | 149 | 1 (0.67) |
| Immunocompromised | ACV treated | 95 | 6 (6.3) |
| Immunocompetent | Unknown | 918 | 1 (0.11) |
a
These numbers relate to the number of patients shedding ACV-resistant virus. A series of resistant isolates from a single patient were scored only once.
b
Most patients were receiving episodic treatment.
