The Louisiana Department Of Health has reported five cases of neuro-invasive West Nile virus in Louisiana, which is the most severe of the different virus strains.

The neuro-invasive strain can cause paralysis, brain damage, and even death as it attacks the brain and spinal cord. However, it is more prevalent in humans with weaker immune systems and those who are sixty years or older.

Researchers say currently there's no medicine to treat the neuro-invasive strain, but it is the most rare type of West Nile virus.

Experts say to protect yourself by wearing long sleeves and pants in areas where mosquitoes are thick and to wear bug spray.  Also, eliminate standing water around your home.
