Sentence examples for period vector from inspiring English sources

When the vectorial capacity of a mosquito for an arbovirus is considered, many factors come into play, including mosquito survivorship, density, proportion of infected mosquitoes that are feeding, extrinsic incubation period, vector susceptibility, and density of susceptible hosts (27 ).

The second section (II) includes the extrinsic incubation period, vector death rates and signifies the amount of time the virus is developing inside the vector taking into account the lifespan of the vector.

Assuming Δt as the sampling period, observation vector is Y(N) = [δ(0), δ Δt), ⋯ δ(NΔt)] T. The parameter vector can be solved by using the least square method as follows.

Midge biting rate, extrinsic incubation period and vector mortality rates are all known to be temperature dependent, and all influence the transmission of a vector borne disease [ 18].

The incubation period after vector transmission is also highly variable (typically 2 6 months but varying from 10 days to >10 years [ 1]).

For example, during the period of vector activity, dengue cases obtained from mandatory notification or from the laboratory network are immediately reported by the French Institute for Public Health Surveillance to the regional officers supervising the enhanced surveillance system.

During the period of vector activity (May November), the estimated number of dengue cases was 39 (95% CI 26 87) for 2007 and 189595% CI 14 37) for 2008 in the 4 departments where the Ae. albopictus mosquito was established at that time; the estimated number was 36 (95% CI 24 79) for 2009 and 234 (95% CI 216 264) for 2010, when a fifth and sixth department, respectively, became affected (Table 2).

(26 The first equation indicates that in each period M vectors of state x t|t ij are generated, and each of them is weighted by the probabilities of coming from a given regime St−1 and of being in another regime S t.

From the weekly GWM locations for the epidemic period geographic vectors were created and analyzed to establish a statistical mean direction for each of the three moving patterns of the GWM.

If zoonotic, transmission of SBV could have occurred through vector-borne transmission during the period of high vector density in summer and fall 2011.

Increased average temperatures could prolong peak periods for vector-borne diseases (6) and extreme weather events such as cyclones and floods can create ideal conditions for the spread of vector-borne and diarrheal diseases such as cholera (7).
