The Centers for Disease Control and Prevention released new data reporting a record number of cases of tickborne diseases, increasing from 48,610 in 2016 to 59,349 cases in 2017.

Why it matters: All types of tickborne diseases rose, including Lyme disease, Rocky Mountain spotted fever and Powassan virus disease. But, the U.S. is not prepared to control the growing threat posed by ticks, mosquitos and fleas because 84% of local vector control organizations lack at least one critical capacity, per an earlier CDC report.

The exact reason for the rise in diseases is unclear to this point. Tick numbers vary from year to year, depending on variables like rainfall, humidity, temperature and host populations. Plus, the number of reported illnesses is also likely larger than what is reported, according to the CDC, since underreporting these disease is common.

What's next, per CDC: The country must develop better techniques to control tick populations and prevent the spread of the diseases. The country needs to improve upon surveillance, diagnostics, reporting and vector control. The development of new vaccines also may also help.

Hurricane Zeta has killed at least one person after a 55-year-old man was "electrocuted by a downed power line" in Louisiana as the storm caused widespread power outages Wednesday night, per AP.

What's happening: Zeta made landfall south of New Orleans as a Category 2 hurricane earlier Wednesday before weakening to Category 1. But it was still "battering southeastern Louisiana and southern Mississippi with life-threatening storm surge, high winds, and heavy rain" late Wednesday, per the National Hurricane Center.

NIAID director Anthony Fauci told the Journal of the American Medical Association on Wednesday he doesn't expect a COVID-19 vaccine to be ready until January 2021 or later.

What he's saying: Fauci said during the interview that the U.S. was in a "bad position" after failing to keep case numbers down post-summer. "We should have been way down in baseline and daily cases and we’re not," he said.
