Transmission of Enteric Viruses through Saliva
by Gertrud U. Rey Norovirus and rotavirus are considered to be enteric pathogens because they are traditionally thought to be transmitted by the fecal-oral route; i.e., when consuming food prepared by someone who did not wash their hands properly after using the bathroom. Unlike rabies virus, which replicates in the salivary glands and transmits through […] (Source: virology blog)

All you need to know about waterborne diseases
Waterborne diseases are contracted through exposure to contaminated water including drinking water, water used in food preparation, and swimming water. They can be caused by bacteria, viruses, and parasites. Below is a partial list of waterborne disease pathogens, their microbial classification, and their resulting illnesses. Classification Microorganism Disease Bacterium Campylobacter spp. Campylobacteriosis Bacterium Escherichia coli E. Coli Diarrhea Bacterium Legionella pneumophila Legionnaires’ Disease Bacterium Salmonella enterica Salmonellosis Bacterium Salmonella typhi Typhoid fever ...

How many diseases are preventable by vaccines?
The power of vaccines cannot be underestimated. Take, for example, Poliomyelitis, which was a significant problem 70 years ago – and is now close to becoming a disease of the past. Not that long ago, smallpox was completely eradicated through the use of a vaccine. As the world celebrates the imminent arrival of several COVID-19 vaccines, we might ask how many diseases are preventable by vaccines as of 2020. Which diseases haven’t got a vaccine yet? Of the 361 generic infectious diseases that affect humans, only 62 (17%) are preventable by vaccines. Over 100 of the remainder are caused by fungi and pa...

21st century outbreaks
Which diseases have generated the highest number of cases from outbreaks during the first two decades of the 21st century? In this blog, we can use GIDEON’s data to find out. ‘Disease outbreak’ is a scary term for many, but every year we suffer dozens, if not hundreds, of localized and international disease outbreaks across the world. While these outbreaks are always significant to those affected, they rarely generate headlines, and can sometimes go unnoticed outside of the Healthcare Industry. An “outbreak” is often defined as an increase in case numbers for a particular disease in a defined place and...

How to Practice High-Quality Telemedicine in the Era of COVID-19
By ANISH MEHTA, MD My practice received its first question about coronavirus from a patient on January 28, 2020. Though there were over 200 deaths reported in China by that time, no one could have imagined how drastically this would come to disrupt our lives at home. Thankfully, I had a head start. As a doctor at an integrated telemedicine and primary care practice in New York City, nearly two out of every three of my medical encounters that month was already virtual. I spent much of January caring for patients who had contracted seasonal viruses, like influenza or norovirus (i.e. the stomach flu). My patients ...

Some unconventional thoughts on coronavirus (COVID-19)
Public health authorities are advising frequent hand washing and social distancing, especially in the absence of confirmatory testing for COVID-19. I don’t have any wisdom to add to these practices. Vaccines are in the works, as are anti-viral drugs—nothing to add here, either. But let me reiterate what we do in the Wheat Belly and Undoctored lifestyles. In general, we do not treat diseases; we correct the factors that allow disease to emerge in the first place—a big difference. Take rheumatoid arthritis, for example. In conventional healthcare, the joint pain and swelling of rheumatoid arthritis are sup...

How to talk to teens about the new coronavirus
We seem to be stuck in a nonstop news cycle about the new coronavirus that is causing an illness called COVID-19. Many parents are understandably sharing concerns, too — at least among friends and families. It’s also possible that teenagers are talking to their own friends and surfing the web and social media sites to gather information, including potential misinformation. How can you make sure teenagers are informed just enough without feeling overwhelmed, yet also have accurate information? Your teen already may be asking many questions. Even if not, it might be a good idea to find out what your teen has heard in cas...

Smartphone and Paper Microfluidic Device for Norovirus Detection
Researchers at the University of Arizona have developed a simple and inexpensive method that can be used to detect tiny traces of norovirus in water samples. The technique involves a smartphone camera and a paper microfluidics device, and could help to identify sources of norovirus before it can cause illness. In the US, norovirus causes approximately 20 million cases of food poisoning annually. However, the virus isn’t just responsible for temporary illness; it can sometimes lead to death, and is estimated to cause 200,000 deaths globally every year. The virus often blazes through confined areas, such as cruise sh...

Beating the Travel Bug & Innovation in Hand Sanitation: Interview with Zoono CSO Dr. Andrew Alexander
While flu season is drawing to a close, transmission of germs can still lead to colds and serious respiratory diseases. In few places are individuals more exposed to a multitude of unique germs and germ carriers than during travel. Unlike some forms of travel, such as buses, where an individual can choose to get off the vehicle or find an alternate transit option, like carpooling, air travel is much less flexible. Based on data from the Bureau of Transportation Statistics, in 2010, on average 1.73 million passengers boarded domestic flights every day in the United States. On a plane, individuals are confined in a tight env...

Norovirus Infection in South Korea
The following background information on Norovirus infection in South Korea was abstracted from Gideon and the Gideon e-book series. [1-3] A computer-generated parsing program of PubMeD and ProMED identifies 22,521 published Infectious Diseases outbreaks. 735 of these outbreaks specify Norovirus as the disease agent. South Korea accounts for 0.67% of all outbreaks, and for 1.5% of Norovirus outbreaks. Details of the individual events are summarized in table 1. Further analysis of these sources identified 59,774 prevalence / seroprevalence surveys. 745 of these surveys examine the prevalence of viral agents associ...
