Whether the recurrent episode is symptomatic or asymptomatic may depend, at least in part, on the number of virus particles present at the skin surface.
Asymptomatic infection of controls is possible and may be common.
In this leaflet, it is recommended that family practitioners perform screening examinations on asymptomatic men over the age of 50 every 2 years.
In each case, the second or third infections were several weeks after the previous one and followed a prolonged asymptomatic period.
This approach will, we believe, prove more economical in the long-term, making the patient asymptomatic and removing the need for repeated hospital admissions.
The development of collateral circulation is more prominent in younger children, and asymptomatic cases with extensive occlusions are seen only among children.
Although symptomatic recurrences are greatly reduced with suppressive therapy, there remains a potential problem of asymptomatic viral shedding.
All patients are alive and asymptomatic on no medication during a follow-up period of two months to 3.1 years (mean 1.04 years).
