Wisconsin health officials say a second child has died from the flu this winter, and there's been a big rise this week in flu-related hospitalizations.

The Department of Health Services says it also still regards the coronavirus as a very serious matter despite no new additional cases of that reported in Wisconsin. Also, officials say the coronavirus diagnostic test kits the state received from the Centers for Disease Control are flawed.

The new coronavirus disease that was first identified in Wuhan has received an official name from the World Health Organization: "COVID-19."

"COVI" comes from coronavirus. The "D" stands for disease. The 19 represents 2019, the year the virus was first identified, in December.

The name will apply for the "entire spectrum" of cases, from mild to severe, according to a WHO spokesperson.

Wisconsin health officials reported on Friday that the number of confirmed cases of the novel coronavirus in the state remains at one.

Officials say the female Dane County resident, who is infected, is doing well, but remains in isolation at home.

On Thursday, the state said the number of potential cases investigated has gone up to 14. But eight test results have come back negative. Results on the other five Wisconsin individuals who have been tested for the virus may be available by the middle of next week.

The World Health Organization announced Thursday that the outbreak of a deadly and fast-spreading strain of coronavirus constitutes a global health emergency.

"Over the past few weeks, we have witnessed the emergence of a previously unknown pathogen, which has escalated into an unprecedented outbreak and which has been met by an unprecedented response," WHO Director-General Tedros Adhanom Ghebreyesus told reporters in Geneva.

The first human-to-human transmission of the deadly Wuhan coronavirus has occurred in the U.S., the Centers for Disease Control and Prevention announced Thursday.

The respiratory virus was spread from a woman who had recently traveled in China to her husband when she returned to Chicago, CDC Director Dr. Robert Redfield said at a press briefing.

It's the sixth confirmed case of the new coronavirus, or 2019-nCoV, in the U.S.

As the Wuhan coronavirus continues to spread, officials in China are urging citizens to wear masks in public to stop the spread of the virus — and cities in China as well as other parts of Asia are reportedly running out of face masks.

But can a mask really keep you from catching the virus?

To answer that, it helps to clarify which kinds of masks we're talking about.
