The sequence of events in this case is consistent with transmission by transfusion of HIV-contaminated plasma collected from a donor during the eclipse period of acute infection (i.e., the interval between infection and the development of detectable concentrations of HIV RNA in plasma) to a recipient treated with medication that suppressed HIV replication, reduced the CD4 lymphocyte count, and blunted the humoral response to HIV infection.

But several features of the newly discovered radio-emitter, including its fluctuating eclipse period, indicate this pulsar may be undergoing a different, possibly earlier, stage of evolution than the "black widow" -- one in which gravitational capture of matter from the companion also contributes to the eclipsing phenomenon, he and Lyne say.
Wildlife officials at the Van Vihar National Park, who for the past seven days were keeping a close watch on the animals to analyse the impact of eclipse on them, said that during the eclipse period, the tigers behaved differently.
For HIV infection, the period after infection until virus is detectable by methods such as PCR is called the "eclipse period," and the period until antibodies to the virus are detectable by serologic methods is called the "window period." On the basis of the limited data available, the average eclipse period for HIV infection is estimated to last 10-15 days but can be longer (1,3).
