In Ghana to date Mosquito Alert has received a total of 98 reports from 47 participants. Of these, 40 (41%) are reports of adult mosquitoes, 17 (17%) are reports of mosquito breeding sites, and 41 (42%) are reports of mosquito bites.

Reports

By administrative subdivision

The following plots show the number of reports received to date by report type, aggregated at two administrative levels.

Over time

The first plot shows the cumulative number of reports received countrywide. The remaining plots show, for the 10 administrative units (at each available level) from which the most reports have been sent, the cumulative reports over time (line plots) followed by the daily reports stacked over time (area plots).

Sampling Effort

Mosquito Alert estimates sampling effort as the expected number of participants who send at least one report from a given 0.025° longitude/latitude grid cell on a given day (the expected-value measure, SE_expected, rather than the simple probability of at least one report). Summed across grid cells and days, it can be read as the expected number of participants sending at least one report from an area over the period. Each grid cell is assigned to an administrative unit using the location of its centre.

Worldwide, the cumulative sampling effort to date is 53,461 (the expected number of participants sending at least one report, summed across all grid cells and days), drawn from 162,179 grid cells and 1,904,740 participant-days recorded between 2014-06-14 and 2026-07-14.

In Ghana, the cumulative sampling effort is 19 — about 0.03% of the worldwide total (ranking 111 of 213 countries), across 144 grid cells.

By administrative subdivision

The following plots show the total sampling effort to date by administrative unit, at the two administrative levels.

Over time

The first plot shows this country’s cumulative sampling effort over time. The remaining plots show the cumulative sampling effort over time for the 10 administrative units (at each available level) with the most sampling effort.

Operating Systems

Of the total of 98 reports that Mosquito Alert has received to date from Ghana, 83 (85%) were sent from Android devices and 15 (15%) were sent from iOS devices. The following plot shows the time series of total cumulative reports sent from iOS and Android devices from the start of the project in 2014 to date.
