Summary:

• As Joe Biden said, the pandemic is over. 
• The official word must come from the World Health Organization, and last week Director-General Tedros Ghebreyesus said the end is in sight.

• Yesterday, Japan moved back to being #1 in new cases with 61,478.  #2 Russia, #3 Germany, #4 Taiwan and #5 USA with 38,464.
• On 10January2021 the U.S. had 4.7 million new cases and 3466 new deaths.  Yesterday, down to 222 new deaths, plus more than 100 times lower new cases compared to 10January2021.
• In a bad year, the flu has killed around 300/day during the season.  COVID is already below that rate.  Here is how the current flu season (red line with triangles) compared with previous years.  A bit complicated, but ILI stands for respiratory illnesses that cause fever plus a cough or sore throat.

Now on to the topic of the day.  I've shown this graphic before.

I've also  shown this.

So this statement to the right is not correct.  Mosquitos are more dangerous than Homo sapiens.  My point, of course is that sharks have a fallacious reputation.  For every human killed by sharks, we terminate 30 million of them.  The ten or so of us done in by sharks are the result of only 80 unprovoked attacks by them annually.  There are almost 500 species of sharks, and three are mostly responsible for fatal attacks:  great white, tiger and bull.

Last month a snorkeling woman was bitten on her leg off the coast of Cornwall, located in the southwest corner of the country.  So what?  Well, this is the first time that a shark attacked anyone in the United Kingdom since 1874, 175 years ago.  And she had paid $200 on an excursion to see Blue Sharks. The country has 11,000 miles of coastline.  Hawaii has only 750 miles, but "suffers" 2 to 3 attacks each year.

The moral of this story is that if you are afraid of sharks, go to the UK or Sahara Desert.  Avoid Hawaii.  Mind you, since 1828...and that's almost 200 years...there have been a total of 116 confirmed shark attacks and ONLY 8 CONFIRMED FATALITIES.  That is sharks kill a human in Hawaii every quarter century.  But if you really want to know, Maui is where the most attacks occur, and here are the beaches you might want avoid on that island.

In the Atlantic, Hurricane Fiona at 130 MPH is heading for landfall over Nova Scotia tomorrow morning.

The more worrisome one for the USA is Tropical Depression 9, which formed just off Venezuela, is destined to become hurricane next Monday, roll over Cuba as a Category 2, and crash into the west side of Florida, perhaps as a Category 3, on Wednesday.  Could be named Hermine or Ian, depending on when it becomes a tropical storm.

The following find stunned me.  That above graphic of what animal causes the most human deaths is hard to believe.  Did you know that elephants kill 500 and dogs 20,000 humans every year?  The one that most startled me, though, is that a freshwater snail kills 20,000 of us annually.  So I had to check and found an article that indicates this freshwater snail, from a WHO report, annually causes 200,000....not 20,000...human deaths. That's 548 human deaths/day.

What happens is that this creature carries a parasitic disease called schistosomiasis, which infects 250 million people/year, mostly in Asia, Africa and South America.  And also Hawaii.  I've seen signs when I once hiked.   Never took them seriously Afraid of sharks?  Read this.

You do contract it from just wading, swimming, entering the water in any way, and the parasites (a parasitic worm, Scistosoma, a blood fluke, photo below) basically exit the snails into the water and seek you. And they penetrate right through your skin, migrate through your body, end up in your blood vessels where they can live for many years even decades. It's not the worms that actually cause disease to people, it's the eggs. And those eggs have sharp barbs because they eventually need to make it back out of the human body and back into the water and find that there are snails that they need to complete their reproduction cycle. And so those eggs can lodge in different tissues and cause severe symptoms ranging from anemia and fatigue, all the way to various severe symptoms, even death in about 10 percent of chronic cases.

Let me further scare you.

The common symptoms of schistosomiasis are:

• Abdominal pain, diarrhea, and blood in the stool 
• Pain while peeing, and the urge to pee frequently
• Blood in the urine
• Persistent cough, shortness of breath, and coughing up blood
• Headaches, seizures, dizziness, and numbness in the legs

Then:  liver enlargement, blood in urine, bladder cancer, anemia, stunted growth in children, etc.  NO VACCINE available.

Finally:

Here are some precautions that you can adopt while visiting affected areas:

• Avoid swimming, paddling, fishing, or washing in freshwater. Swimming in chlorinated pools and the ocean is safe. 
• Only drink boiled or filtered water. If possible, consume only mineral water. 
• Beware of the locally sold medicines that are advertised to treat schistosomiasis. Often you will end up buying fake drugs in incorrect dosages.
• There’s a misconception that drying your body quickly with a towel prevents infection. But this trick doesn’t work against it.

Wow, what a way to end the week.  Sorry.  I was thinking of deleting this addendum.  But, it might save a life.
