It has been announced by health officials that first human West Nile case of this year in Tarrant County has been confirmed in the southwestern area of the county. Tarrant County Public Health Director Vinny Taneja said the unidentified patient has got West Nile neuroinvasive virus, which is a very severe form.

The health department didn't reveal if the person is male or female or was suffering from any other health conditions.

As per reports, University of North Texas Health Science Center students are studying the mosquitoes in a lab dish. Symptoms for the severe form of the condition include stupor, neck stiffness, coma, disorientation, tremors, muscle weakness, convulsions and paralysis. This form of the virus could be fatal.

Approximately 1% of those who are attacked by an infected mosquito develop the more serious type of the condition.

According to Taneja, "We did get a history of mosquito bites. This person did recall being bitten by mosquitoes in recent weeks. A couple of neighboring counties have seen cases, and this might be the beginning of where we start seeing more human cases".

It has been reported that as much as 80% of those who were attacked by West Nile have no symptoms and approximately 20% will develop West Nile fever. Symptoms of the condition include nausea, fever and fatigue together with muscle and joint aches. Most of the patients recover on their own, however this can take a number of weeks.

In 2014, the first out of 16 Tarrant County human West Nile cases was reported on August 4. There were no reports of death.
