Two clocks decide the response window. PHLT 8072's natural history profile example for Week 3 sets dengue's human and mosquito incubation periods on one timeline for a composite coastal county.

What a finished PHLT 8072 Week 3 natural history profile looks like
At its center sits a single horizontal timeline, drawn across the top of the first page and labeled a schematic without day counts. It begins with an infective bite, marks the intrinsic incubation period in the person, then a viremic window during which a feeding Aedes mosquito can acquire the virus. A second bar starts at that feed: the extrinsic incubation period, while the virus travels to the mosquito's salivary glands before the insect can transmit. Below the timeline, three paragraphs match responses to intervals. Case reporting and household inquiry begin only after illness is recognized, which may fall late in the viremic window. Bite avoidance by a viremic person acts inside that window. Larval and adult mosquito control act on the second clock. The page ends by listing what the profile leaves uncertain, including inapparent infections.
How a PHLT 8072 Week 3 example is structured
The timeline comes before any prose, because the profile's claim concerns sequence and a reader should see the intervals before meeting an argument about them. Terms are fixed early: incubation for the time to symptoms, latency for the time to infectiousness, and the infectious period for the stretch when a mosquito could be infected, since these three drift apart for a vector-borne agent. One sentence goes to the Ross-Macdonald line of models, for the insight that the extrinsic incubation period competes with the mosquito's own survival, so fewer insects live long enough to transmit when that interval runs long. Responses are then ordered by which clock they act on, person first and mosquito second. The uncertainty section closes the profile and treats inapparent infection as a structural gap in any response that starts from reported cases.
One timeline, two bars
Intrinsic and extrinsic incubation share an axis, marked schematic, with the viremic window where they meet.
Three terms kept apart
Incubation, latency and the infectious period are defined separately because for this agent they end at different points.
What the person's clock allows
Reporting and household inquiry wait on recognized illness, which can leave little of the viremic window to act in.
What the mosquito's clock allows
Larval and adult control act during the interval before a newly infected mosquito can transmit.
Infections nobody reports
Inapparent cases feed mosquitoes without ever reaching a clinic, a gap in any response built from case reports.
Where marks go in PHLT 8072 Week 3
Defining the intervals before using them decides most of the grade. Profiles that treat incubation and infectious period as one number lose ground at once, and this one separates three terms in its opening section. The second clock draws the largest block: recognizing that the mosquito's incubation period opens a window for vector control that case-based measures cannot reach is the insight the week is built to test. The Ross-Macdonald sentence is credited when it explains why that window matters, not when it is merely cited. Matching each response to an interval earns structural credit. Naming inapparent infection as a gap adds a share for realism. Weaker profiles quote day counts without sources, draw the timeline for the person only, or recommend responses without saying which interval each one fits.

PHLT 8072 Week 3 questions, answered
What is the extrinsic incubation period?
The interval between a mosquito taking in virus from an infected person's blood and becoming able to pass it on through a bite. During that time the virus replicates and reaches the salivary glands. Temperature affects its length, which is why the profile treats it as variable and gives no day count. A custom profile for another vector-borne agent describes that agent's equivalent interval from cited sources.
Why not give the incubation periods in days?
Because the profile is about how intervals relate, and any figure quoted without a source would read as a finding. Published references give ranges for both periods, and a paper for your course should cite them directly. The schematic shows order and overlap, which is what the response argument needs. When your prompt asks for durations, the custom sample takes them from a named reference and credits it.
Does the profile tell residents how to protect themselves?
It does not. Bite avoidance and mosquito control appear only as responses whose timing is analyzed in an invented county, never as recommendations for anyone. Personal protection advice comes from health departments and clinicians. Households, cases and the coastal setting were all assembled for the page. A custom profile follows whatever setting your prompt describes and keeps the same distance from advice.
