Around 8 in 10 people infected with West Nile virus don’t show symptoms. These symptoms can often be confused with those of other viruses, so the majority of West Nile cases are never diagnosed. The CDC’s tally for West Nile cases this year is likely an undercount, since several states have reported additional human cases in recent weeks. Raman said he’s worried about more West Nile transmission during monsoon season in the Las Vegas area, which is expected to start soon. The county announced in late June that one person, a blood donor, had tested positive for West Nile virus.
