Norovirus is one of the leading causes of acute gastroenteritis worldwide. Although it is becoming clear that viral excretion in the stool continues even after the clinical symptoms have disappeared, the factors that determine its duration remain unknown. Between 2007 and 2009, all inpatients and medical staff at our hospital who showed symptoms of a new onset of gastroenteritis were asked to submit a sample for norovirus testing by real-time RT-PCR. One of the 273 patients included tested positive for GI norovirus, and a further 89 were positive for GII norovirus. Of these 90 norovirus-positive individuals, 76% excreted norovirus RNA in the stool for more than 7 days. The inpatient group contained more long shedders than the medical staff group (5/32 versus 1/39, P<0.05). The median viral shedding duration was 19.3 and 15.2 days for inpatients and medical staff, respectively. Among hospitalized patients, younger individuals, those with a higher viral copy number, and individuals receiving immunosuppressive therapy tended to require a longer time to eliminate the virus. These patients should therefore be monitored and managed carefully to prevent nosocomial spread of the disease.
The luminosities, colors and H\alpha\ emission for 429 HII regions in 54 LSB
galaxies are presented. While the number of HII regions per galaxy is lower in
LSB galaxies compared to star-forming irregulars and spirals, there is no
indication that the size or luminosity function of HII regions differ...
We introduce an epidemiological model where infectives leave the
Epidemic, either by recovery or sampling, after some random time which may
Follow an arbitrary distribution.
We derive an expression for the likelihood of the phylogenetic tree of
Sampled infectives under our general epidemiological...
Is it true that a graph with a sufficiently small number of k-cliques and
k-anticliques must contain an induced copy of every k-vertex graph? Here we
prove this claim for k = 3 with a sharp bound. A similar phenomenon is
established as well for tournaments with k = 4.
