Mosquito and vector surveillance

Mosquitoes counted before they spread disease.

Dengue, malaria, West Nile and other vector-borne diseases follow mosquitoes, and mosquitoes follow heat, rain and standing water. Counting traps that report daily, with weather and water sensing, show where populations are growing so control teams act before cases rise.

  1. Health · Mosquito and vector surveillance

    Disease follows the mosquito

    Dengue, malaria, West Nile and other vector-borne diseases follow mosquitoes, and mosquitoes follow heat, rain and standing water. Invasive species are spreading into new areas. Manual trap counts arrive weeks late, after populations have grown and control is harder. Measurement turns that risk into decisions made in time.

  2. What is measured

    Counts, weather and water

    Counting traps across suburbs and wetlands count mosquitoes every day and group them by type. Weather stations in the network measure temperature, humidity and rain, and level sensors at drains, ponds and storm channels show where water stands long enough for breeding.

    Counting traps · Weather stations · Standing water sensors
  3. The base node

    Pulses forecast

    The node turns daily counts into population trends, links them with heat, rain and standing water, forecasts the next breeding pulse and ranks areas for control teams, so effort goes where populations are about to grow. Nothing is lost when a link drops; the node keeps it.

  4. Radio and links

    Suburbs and wetlands

    Traps and sensors across suburbs and wetlands reach gateways over a low-power link, on batteries and small solar panels. Gateways and the node send data over cellular to the health authority and its control teams. Each link is chosen for the place, not from a catalogue.

    LoRaWAN · Public cellular
  5. How it works

    From heavy rain to targeted control

    Heavy rain fills storm channels in two districts and warm nights follow. Standing water sensors stay high and the node forecasts a breeding pulse within days. Control teams clear and treat the channels; the next counts stay flat where the pulse was due.

    Scope with the health authority

    The scope reads the authority’s vector species, diseases, past outbreaks, existing traps and control teams. Nexus Observatory Inc. returns the trap network, forecasting design and a price per area and per year. Every assumption in the scope is written down and priced.

  7. From order to operation · Survey

    Survey breeding sites

    Crews and entomologists survey breeding sites, trap positions by habitat and housing, standing water, gateway coverage and access. Findings are mapped with photographs. Every finding is kept with the site record for the crews who follow. Findings shape the kit for each site before anything is built.

  8. From order to operation · Permits

    Land and community notice

    Land owners and the city approve trap and sensor sites, and communities are told what the traps do. Every approval is kept with the area record. Approvals are tracked site by site, so nothing waits unseen. No crew goes to site before its approvals are in place.

  9. From order to operation · Build

    Build and validate

    Counting traps are validated against manual identification, weather and water sensors calibrated, radios paired and the node configured and enrolled with its identity. Test results travel with the kit to the site. Nothing ships until the whole kit has passed its tests together.

  10. From order to operation · Install

    Install the network

    Crews install traps, weather stations and water sensors, raise gateways on rooftops and set up the node at the health authority. Every point is mapped and photographed. The site record is updated before the crew leaves. Crews follow the site safety plan throughout the work.

  11. From order to operation · Commission

    Commission against manual counts

    Each node proves its identity. Trap counts are compared with entomologists’ manual identification over several weeks, and alerts are tested with control teams. Results are signed and kept with the site record. Acceptance is recorded with the owner before handover.

  12. From order to operation · Operate

    Target control

    Health authorities see populations by area and the conditions behind them. Control teams are sent where populations are growing, breeding sites are cleared after rain, and every action is recorded with later counts. Reports for owners and funders come from the same record.

  13. From order to operation · Maintain

    Service and revalidate

    Traps are serviced and revalidated against manual counts each season, batteries replaced, sensors recalibrated and software updated in rings. Every change is kept with the area record. Spares and procedures travel with the crews. Maintenance history stays with each site for its whole life.

  14. Data products

    For authorities and control teams

    Health authorities and entomologists receive mosquito population trends; control teams receive areas ranked for control; public health planners receive breeding pulse forecasts; regional and international surveillance receive vector records, each tied to trap, area and date. Each product carries its site, time and quality flags.

    See the data products
  15. Evidence

    Surveillance to guidance

    Surveillance follows the invasive mosquito guidelines and supports the global vector control response, and records support reporting under the international health regulations. Every count keeps its trap and validation, and every action its later counts. Records are open to the people who must check them.

01The place and its hazards

Where it runs, and what can go wrong.

Operating contextThe global vector control response calls for strengthened surveillance, invasive mosquito surveillance in Europe follows published guidelines, and countries report public health events under the international health regulations. Manual trap counts are slow and sparse, and arrive after populations have grown.

Hazards

  • Mosquito populations growing unseen
  • Invasive species spreading into new areas
  • Rain and heat that trigger breeding
  • Manual trap counts arriving weeks late
  • Control spread thinly instead of targeted

02What must be measured

What, where, how often, and under which rules.

Each measurement names where it is taken, how often, and the public standard or regulation behind it. Numbers in the sources column open the cited source below.
