The serial interval can be defined as the time interval between a primary case presenting with symptoms and its infectee developing symptoms [7], [8].
A primary case was defined as illness in the first person in a cabin to report ILI symptoms; a co-primary case, as illness in a person who reported symptom onset within 24 hours after a primary case; and a secondary case, as illness in a person whose symptoms developed >24 hours after symptom onset in the primary case-patient.
The role of disturbances in carcinogenesis is well documented and generally accepted, but probably underestimated as a primary cause (Fig. 3, case B versus case C).
Therefore, in addition to ultrastructural changes, decreased expression and the altered expression pattern of nephrin and podocin indicate that podocyte injury and dysfunction likely occurred as a primary event in the present case.
A household contact was any person who lived in the same household as a confirmed primary case-patient and >1 overnight stay after onset of illness in the person who was the primary case-patient (16).
What I've learnt in the process of trying to engineer serendipity is that it is tough to put forward serendipity as a primary use-case.
Cancer registration in Sweden does not use death certification as a means of primary case ascertainment, and the registry, therefore, misses a small proportion of fatal cancers that most other cancer registries would detect and register as 'death-certificate-initiated' cases (Parkin and Bray, 2009).
Eleven patients with secondary cases acquired their infection as a household contact and had only 1 patient with a fully investigated primary case as a possible source.
Ghaziani, who is gay, lived in Chicago's Boystown for much of the aughts, and he uses Chicago as the primary case study.
The added heft and weight make it feel like a much more comfortable handful than many current-day devices, which can tend to feel cheap or less than substantial, especially when they use plastic as their primary case material.
