Japanese encephalitis virus 

Japanese encephalitis virus (JE virus) was detected in Victoria for the first time early in 2022. JE virus is a rare, but potentially serious, infection of the brain caused by a virus spread to humans through mosquito bites.

The virus is mostly spread to humans from pigs via mosquito bites and cannot be spread from human to human. It also cannot be spread by eating pork. 

A comprehensive response across human and animal health sectors is under way in Victoria and to implement control measures. Examples of this response include; vaccinating those at risk, surveillance of animals for JE virus, public health information, and mosquito testing and control activities.

The Beat the Bite website on the Better Health Channel provides information about mosquito borne diseases and mosquito bite prevention for the general public. Find out more by clicking here.

JE virus study

The Victorian Department of Health and Ovens Murray Public Health Unit are conducting a study in this area to understand more about the risk of JE virus.


JE virus is a rare but potentially serious mosquito-borne disease.

By providing blood for this study, you will help us understand how many people have been infected with the virus. This will help us plan our vaccination and other prevention activities.

What’s involved?

To participate, you will need to:

  • Complete a short questionnaire
  • Give a small blood sample – if you are already getting blood taken for another reason this will not require an extra needle

You will be informed of your individual test results.

Who can be involved?

Participants must not have been:

  1. Previously vaccinated for JE virus
  2. Previously diagnosed with JE virus
  3. Born in one of the following countries: Bangladesh, Brunei, Burma, Cambodia, China, Guam, India, Indonesia, Japan, Laos, Malaysia, Nepal, North Korea, Pakistan, Papua New Guinea, Philippines, Russia, Saipan, Singapore, South Korea, Sri Lanka, Taiwan, Thailand, Timor-Leste or Vietnam  

All ages are welcome, however children aged under 18 years must be accompanied (and have consent provided) by a parent or guardian.

How do I take part?

This study is being conducted through your local pathology providers.

  • Dorevitch Pathology Wodonga – 101 Hume St , open Monday to Saturday, 7.30am to 5pm
  • Dorevitch Pathology Wangaratta – 74 Ovens St, open Monday to Friday 7am to 5pm and Saturday 8am to 11am.
  • Dorevitch Pathology at Rutherglen Medical Centre, 1/172 High St, open Monday to Thursday 8am to 11am.

You will be provided with a study information sheet. If you are happy to participate, please complete the consent form and questionnaire. Once these are completed, a staff member will give you a pathology slip for the study so that you can have your sample collected.

The results of the study will be pooled and published together. No individual results will be published. We will provide you with a summary of the study results once they are available. The study findings will also be published in both investigator theses and journals.

If you have any questions about this study, please do not hesitate to contact the Ovens Murray Public Health Unit on phu.communications@awh.org.au or by phoning (02) 6048 1000.
