Colusa County has reported its’ first confirmed human case of West Nile Virus for 2016.  The case was the more severe neuro-invasive form of the illness that causes meningitis.  The patient, an adult, is recovering at home.  The patient resides outside of the Colusa Mosquito Abatement District.

Most people (70-80%) who become infected with West Nile virus do not develop any symptoms. About 1 in 5 people who are infected will develop a fever with other symptoms such as headache, body aches, joint pains, vomiting, diarrhea, or rash. Less than 1% of people who are infected will develop serious illness.


Although Colusa County reports few WNV cases each year, 2 cases in 2015 and 3 in 2014, this does serve as a reminder that residents should take simple precautions to avoid exposure to mosquitos.  The 4 “D”s is an easy way to remember how to prevent mosquito bites.

1. DEET – Apply insect repellent containing DEET, picaradin, oil of lemon eucalyptus or IR3535 according to label instructions. DEET can be used safely on infants and children two months of age and older. 

2. DAWN AND DUSK - Mosquitoes bite in the early morning and evening so it is important to wear proper clothing and use repellent if outside during these times.

3. DOORS AND WINDOWS - Make sure doors and windows have tight-fitting screens and are free of tears or holes, to keep out mosquitoes.

4. DRAIN - Mosquitoes lay their eggs on standing water. Eliminate or drain sources of standing water such as flower pots, old car tires, bird baths, pet bowls and buckets.  Report swimming pools that are not being properly maintained.
