1. Mosquitoes as a Vector of Disease in Ireland
George Sharpson
P.E.H.O.
Fingal County Council.

2. La Reunion Outbreak in 2006. Chicungunia Epidemic in 2006.
A quarter of the Population affected.
Many Severe Cases.
155 Deaths.
Primarily in elderly people.

3. Chikungunya, a virus spread by mosquitoes
Symptoms :
‘Chikungunya’ from a Kimakonde language, meaning ‘to be contorted', due to joint pain(arthalgia)
High Fever
Rash
Death
Majority, mild and self limiting.

4. The Vector Aedes albopictus Asian tiger Mosquito.
Previously the host was Ades aegypti.
This species jump took scientists by surprise.

5. EuroSurveillance.org
EuroSurveillanceReleased report of Chikungunya Virus in Ravenna Italy in 2007.
Traveler from India carried Virus in June 2007(index case)
By August 334 cases
Previously never been a problem in Europe
Asian tiger is native to Italy
Bit the traveller to Italy
Spread the disease to other hosts.

6. Spread Throughout Italy by end 2007. Into parts France by 2008
Global Warming may become a factor.
Mild winters.

7. The Situation in Ireland
HPSC (Health Protection Surveillance Centre) concerned over Ireland ‘s exposure
Ireland & Britain could be next.
Ireland has approx types of Mosquito.
Types unknown.
National monitoring project.
Consulted Dr. Tom Kelly Senior Lecturer, Department of Zoology, Ecology & Plant Science, University College Cork.

8. Training at UCC EHOS 2 day course in Cork. Mosquitoes Caught.
Frozen or gassed.
Identification using microscopes.
Manuals provided.
Classifications of Irish & British (6 Genae- Anopholies,Culex, Orthopodomyia,Adies, Culisetta,Coqullettidia).

9. Eisen Trap How to trap a mossie? Killgerm –Eisen Trap
Attracted to Sweet Scent Lure
Fan draws mossie into net.
Mossie taken back to lab for freezing and identification

10. Choice of location Project started in 2009. Malahide Castle
Fingal Co Co controlled property.
Electricity available
Dry Environment.
Known Mossie hangout.

11. Problems Sweet Scent lure not effective
Very difficult to identify after freezing
Misidentifications.
Very few catches
tried different traps using CO2, light etc. without success.

12. Findings. The majority of mosquitoes seen were found to be ornitologic
i.e. depending on birds as hosts rather than humans, with accidental human biting.

13. UCC identified the following
Culex pipiens, the vector for WNV in the United States is also common here. Although it generally only bites birds it was felt that further clarification should be sought on whether it will also bite humans.
C. annulata,
Aedes detritus (which will bite humans) were most common.
and A. clavigar.
NO Aedes albopictus were found to date.

14. Change of Tack! UCC recommends a change in strategy.
Larval Stages to be caught and identified.
This has been tried and tested in UCC and works.
Next Step is to rewrite the software!

15. Thank You. Any Questions?
