Correction: this is not the worst season for West Nile fever in USA
In a previous alert, Sitata referred to the current West Nile fever transmission season as one of the worst ever in the USA. The original source was in error. The season so far this year is rather mild with only slightly more than 300 reported cases so far.
Sitata regrets the error in the previous alert. The risk for the general traveller remains low.
