When Viruses Collide with Parasitic Worms

COVID-19 Data Shows the Importance of Thymic Atrophy in Aging
The decline of the immune system is of great importance in aging. Vulnerability to infection, a decreased surveillance of senescent cells and cancerous cells, and growing chronic inflammation all take their toll. A sizable fraction of this problem stems from the diminished supply of new T cells of the adaptive immune system. T cells begin life as thymocytes in the bone marrow, then migrate to the thymus where they mature. Unfortunately, the thymus atrophies with age, a process known as thymic involution, in which active tissue is replaced by fat. The T cell supply falters, and as a result the existing T cell population bec...

Disease names – what do they mean?
In the midst of the continuing pandemic, World Dictionary Day seems like the perfect occasion to consider the meaning and origin behind some of the most well-known disease names. We’ve been speaking with Dr. Steve Berger, our co-founder, to learn more.
CORONAVIRUSES
Let’s start with the obvious one. COVID 19, which began as a localized outbreak of “Novel Coronavirus” infection, is now a name almost every household in the world will know. COVID-19 comes from COrona VIrus Disease which first appeared in 2019, with the disease itself being caused by the SARS-CoV-2 virus.
SARS was a prominent name back in the early 2...

The Itchy, Bumpy Blues: How to Treat and Prevent Mosquito Bites and Related Conditions
Mosquito bites may be a nuisance, but fortunately, in the U.S., they tend to amount to nothing more than that. Upon being bitten, most Americans experience a bit of swelling and itchiness, and nothing more. However, there are exceptions to this, including stronger allergic reactions to bites and cases of mosquito-borne illness.
Insect and arachnid bites, including ticks, account for approximately 2,000 cases of malaria and 30,000 cases of Lyme disease in the U.S. annually. In addition, millions of people worldwide die of malaria each year. It is helpful to protect yourself against insect bites, not only to avoid pesk...

West Nile virus is also on the list
In Caldwell, Idaho, on the Snake River in Western Idaho, Dr. Carolyn Rees tells us that she was at ground zero during a West Nile Virus epidemic “leaving many people with post-encephalitic brain damage”. A review of the research literature on WNV includes a number of studies now documenting enduring memory and other cognitive losses as a predictable outcome of a WNV infection. The prevalence of this kind of virus (an “arborvirus”) is growing continuously in the US. The disease is primarily spread via mosquito-transmitted infections in birds. Where the disease has had a long history, some mammals are...

What ’s in a disease name, anyway? Everything.
Spanish Flu. Japanese Encephalitis. Middle Eastern Respiratory Syndrome. West Nile Virus. Wuhan Virus (and lately, the “Chinese Virus” as many have begun calling the pathogen that causes COVID-19: SARS-CoV-2). What do these names all have in common, you might ask? Well, for one thing, they were constructed not by a strict scientific nomenclature, but by […]Find jobs at Careers by KevinMD.com. Search thousands of physician, PA, NP, and CRNA jobs now.

Don ’ t panic. Prepare
Dr.Tracey McNamara on West Nile Fever and COVID-19
As interviewed by Edward Borton, GIDEON
What was the experience of discovering a new virus outbreak on your doorstep?
When New York City announced that people were dying of unusual encephalitis, I was struck by the timing and proximity between this event and an outbreak of crow deaths. Upon ruling out all known viruses that cause inflammation of the brain in birds, in the United States: exotic Newcastle, avian influenza, and Eastern Equine encephalitis (EEE), I knew this was something new.
It wasn’t until I picked up the phone and called the U.S. Army and sai...

Oh no! Are we all going to die?
Yes. However, very probably not because of the novel coronavirus that has appeared in China. This seems to be front page headlines in every media outlet on the planet, and the World Health Organization has convened a meeting to decide whether to declare an official Global Health Emergency.This sort of flapdoodle happens every time a novel pathogen appears. Back when I lived in the Hub of the Universe a mosquito-borne disease called West Nile virus appeared (having formerly been large confined to, yes, west of the Nile). For weeks, every time a new case was identified it would be on the front page of the Boston Globe....

Kunjin Virus Infection
The following background information on Kunjin virus infection is abstracted from Gideon www.GideonOnline.com and the Gideon e-book series [1] Primary references are available on request.
Kunjin virus (KUN), a subtype of West Nile virus, was first isolated in Australia in 1960, from mosquitoes (Culex annulirostris). The virus is named for an Aboriginal clan living on the Mitchell River in Kowanyama, northern Queensland
Most cases of human infection are reported in Australia, with sporadic reports from Nepal. Serosurveys suggest the presence of human infection in Malaysia, Indonesia and Papua New Guinea.
In Australia...
