Tick-borne Virus: All You Need to Know About the Disease That Has Killed 7 in China

Tick-borne virus: All you need to know about the disease that has killed 7 in China

While the world is fixated on COVID, there are other viruses that are deadly, and SFTS is one of them.
Important points:
  1. Symptoms include fever, coughing, thrombocytopenia (low platelets), leukcytopenia (love white blood cells), neurological issues and gastrointestinal disorders.
  2. SFTS has a 30% fatality rate.
  3. The Asian Longhorned tick appears to be the culprit which is now spreading across the U.S. ,despite the weather, by migrating birds.
  4. They don’t know if human to human transmission occurs.
  5. Since this was first isolated in 2011 you would think we would have better answers for something that kills 30% of the people it infects….

For more:  This article states the woman may have been infected by the bite from a cat.  If this is true, human to human transmission is highly probable.  We need answers on this tick fast because they line up on a blade of grass like a cluster-bomb.  Brush against it and you have hundreds if not thousands of ticks on you all at once.
And while researchers are quick to report it transmits Lyme disease rarely, it’s still a possibility:
uninfected H. longicornis larvae could acquire B. burgdorferi s.s. while feeding on infected Mus musculus mice (infection prevalence >50% in freshly fed larvae) but that the infection was lost during the molt to the nymphal stage. None of 520 tested molted nymphs were found to be infected, indicating that transstadial passage of B. burgdorferi s.s. is absent or rare in H.
This tick should be a grave concern to all of us.

Allegheny County’s Tick Collector Warns of Lyme Disease Risks

Leah Lamonte, vector control specialist for the Allegheny County Health Department, looks for blacklegged ticks in their nymph stage after dragging a cloth along a trail in Hartwood Acres on July 30, 2020, in Allison Park.

Rarely Infected Not Infectious: How Dogs & Cats Have Become Victims of COVID-19


Infected: Can dogs and cats be infected by SARS-CoV-2?

Since the outbreak of the COVID-19 pandemic we have seen a number of positive cases in companion animals (see our blog on why testing in companion animals should be limited). But equally as important, are the negative results.

Infectious: Can dogs and cats transmit SARS-CoV-2 to people? 

“Currently, there is no evidence that animals are playing a significant epidemiological role in the spread of human infections with SARS-CoV-2.” OIE. Evidence of transmission from dogs or cats to people would require clarity on two factors; timing and other transmission routes. A person would need to become sick with COVID-19 after their dog or cat had shown signs of infection AND all other possible routes of transmission from people would need to be excluded. Because they are in contact with many more dogs and cats than most people, veterinarians and shelter workers would be most at risk for this kind of transmission. Thankfully, there appears to be no greater prevalence of COVID-19 in these workforces.

With over 4 million human cases worldwide we have an abundance of complex, uncontrolled but undeniably valuable epidemiological evidence about transmission. The extremely small number of infections from people to dogs and cats, and the lack of any examples of transmission to people, is meaningful.

Dogs and cats are not playing a role in transmission of SARS-CoV-2 to people.

These companion animals are the victims of this reverse zoonosis; they are (rarely) infected but not infectious.

Researcher: ‘No Viable SARS-CoV-2 Detected On Surfaces’ in Real Life Situations

Exaggerated risk of transmission of COVID-19 by fomites

In my opinion, the chance of transmission through inanimate surfaces is very small, and only in instances where an infected person coughs or sneezes on the surface, and someone else touches that surface soon after the cough or sneeze (within 1–2 h). I do not disagree with erring on the side of caution, but this can go to extremes not justified by the data. Although periodically disinfecting surfaces and use of gloves

are reasonable precautions especially in hospitals, I believe that fomites that have not been in contact with an infected carrier for many hours do not pose a measurable risk of transmission in non-hospital settings.

A more balanced perspective is needed to curb excesses that become counterproductive.



Earlier studies did not use real life situations.

In this video, Dr. Popper discusses a study that showed passive contact with bleach (what they are wiping shopping carts and everything else down with) was associated with a major increase in self-reported influenza.








Health Officials Warn Lone Star Ticks Multiplying In Connecticut

Health Officials Warn Lone Star Ticks Multiplying In State

As if Newtown Health District Director Donna Culbert was not busy enough handling coronavirus issues, she is now grappling with the news that the aggressive lone star tick is proliferating in the region.

Culbert, who has made tickborne disease education a hallmark of her administration, told The Newtown Bee this week that the latest news from colleague Goudarz Molaei, PhD, at the Connecticut Agricultural Experiment Station (CAES) is disturbing considering how many local residents are already suffering from related illnesses.

“The Newtown Health District is always concerned about tick bites and tick-borne disease, and news of the lone star tick becoming established in the region adds to the concern,” Culbert said. “Although our office has not yet received a lone star tick submitted to our office for identification yet this year, I am not naive enough to think that they aren’t out there.”

Key Quote:  

Previously limited to the southeastern US, lone star ticks have been detected in areas with no previous record of activity….

And that includes Wisconsin:


….he diagnoses approximately 1 patient per month with Alpha-gal allergy and that the reactions can be severe, from passing out to life-threatening reactions.

The lone star tick is an aggressive biter that gives highly irritating bites.  It’s known to transmit:
