The U.S. Centers for Disease Control and Prevention (CDC) is trying to find out what made at least 400 people sick, on two xmas time cruise ships.

Officials with the CDC suspect norovirus.  The latest cruise ship outbreaks took place on ships belonging to Cunard and Princess Cruises.

In Japan, people are still dying from norovirus.  In a third outbreak just in the Gregorian month of December, four more people have died.  This latest outbreak is taking place in a hospital in Yokohama.  At least 68 patients are sick, as well as  27 hospital staff.

In United Kingdom, more than one million people are confirmed sick with norovirus like symptoms (3,538 have so far been confirmed as norovirus by lab tests, which takes time), and hospitals are being shut down.  The vomiting bug (as it’s called in Britain) has shut down East Surrey Hospital, for the third time in the past two months!  U.K. is experiencing an 83% increase in norovirus cases, compared to the same time last year.  Just in the past two weeks 70 British hospitals have reported outbreaks! To make matters worse, an average of 5,000 health workers have been calling in sick everyday!  Health officials say it’s a little early for the vomiting bug: “The number of laboratory confirmed cases has risen once again as it appears that we have seen the rise in cases that usually begins in January start a little earlier than we normally expect.”-John Harris, Health Protection Agency

Back in the U.S.A., in Illinois officials are reporting norovirus outbreaks in prisons.  At least 140 inmates were sick in the Stateville Correctional Center in Joliet.  Prison officials say the first cases showed up on xmas day.

In Iowa, media in Sioux City are reporting that many cases of norovirus are being misdiagnosed as influenza. In fact, here in the U.S. norovirus is often incorrectly called “stomach flu”.  Another factor is that Iowa doctors and hospitals are not required to report cases of norovirus to state health officials!

A nurse in Maine explains the main differences between norovirus and influenza: “Basically the biggest difference between norovirus and the actual flu is that the norovirus causes nausea, vomiting, diarrhea. The actual flu that we all are vaccinated against every year is mostly respiratory in nature, with cough, aches, fever and chills. As far as numbers of cases, I cannot say exactly how much of either but will say that this is one of the busiest seasons I have seen in a while for both norovirus and the flu.”-Chris Reeder, York Hospital

In California, officials in San Luis Obispo County are reporting what they think is a new strain of norovirus. They are reporting three outbreaks in the past month. It’s thought to have come from Australia.   California has been dealing with norovirus outbreaks all year!  In October a middle school in Oak Park, Ventura County, saw at least 320 students out sick.  A pizza restaurant, in Contra Costa County, was shut down because of the vomiting bug back in June.  In July the Alisal Guest Ranch in the Santa Ynez Valley, Santa Barbara County, was investigated after customers got sick at the end of June.

In Milwaukee, Wisconsin, since September there have been one confirmed and five suspected outbreaks in several nursing homes.

In Michigan, Lansing area health officials are reporting 75 cases at a local retirement home.

There is no treatment for norovirus, no vaccine, and your body does not develop immunity so you can get sick again and again and again….

Check my previous postings about norovirus.  You’ll notice most outbreaks involve hospitals.  You’ll also read about a recent study that says cleanliness might not have any affect on viruses (it’s actually the first study ever to investigate such claims).
