  • “Many COVID-19 patients get secondary infections that are bacterial, so I built my whole exam around it. Students were given data and had to use GIDEON to analyze the secondary infection, how it should be treated, whether it will contribute to COVID-19 resistance, so the role play continued even during the exams.”

  • “Here, we examine the global trends between changes in forest cover in recent decades and epidemics of human infectious diseases, using the GIDEON global database, which is the best available data set on infectious diseases that has already been used in several studies.”

  • “The new version of GIDEON sports a fundamentally redesigned user interface with convenient additions to responsive design and accessibility. <..> This makes GIDEON less of a reference-only resource and more of a hybrid information and diagnosis tool more immediately usable by public health practitioners. “

  • “While the world’s focus has been on COVID-19, sometimes it seems like nothing else is happening in infectious diseases. But that is far from the reality.

    In recent years, we’ve seen Nigeria report large numbers of Lassa fever, we continue to see plague outbreaks from Africa to Asia and monkeypox cases have risen in recent decades.

    Joining me to talk about these other outbreaks is Stephen A. Berger, M.D.   Dr. Berger is the co-founder of GIDEON Informatics (Global Infectious Diseases and Epidemiology Network).”

  • “The bottom line is there is always a risk eating at a restaurant right now,” Dr. Stephen Berger, an infectious disease expert, and co-founder of the Global Infectious Diseases and Epidemiology Network told CNN.
    “Eating means having to take off your mask, and that’s the golden rule of avoiding coronavirus.”
  • “Most viruses that cause human disease are named for the disease itself,” said Stephen Berger, a founder and medical adviser at the Global Infectious Diseases and Epidemiology Network, in an email. “The virus that causes measles is called ‘Measles virus’ and the virus of influenza is called ‘Influenza virus.’ ”

  • Dr. Stephen Berger, double board certified in infectious disease and microbiology and the founder of GIDEON, the Global Infectious Disease and Epidemiology Network, explains to Eat This, Not That! Health that he and his team have been working with a “Computer Expert [Decision Analysis] System” designed to generate a list of diseases based on signs and symptoms. The list is ranked according to statistical probability.

  • With the help of decision support tools, clinicians can differentiate between vector-borne diseases during a season where more people are at risk. A decision support system uses two or more items of patient data to generate case-specific advice. In practical terms, the output of such systems is used to arrive at a specific diagnosis. Although none of these systems can “make” a diagnosis, they are capable of generating a list of diseases that are compatible with a patient’s epidemiological background, signs, symptoms, and laboratory findings.

    Stephen A. Berger is cofounder and medical director of GIDEON, the Global Infectious Disease and Epidemiology Online Network.

  • For example, if a group of American adults is experiencing severe illness, cough and fever, the most likely diagnosis is COVID-19. In this scenario, an infectious disease database platform ranks COVID-19 “number 1,” with a statistical likelihood of 87%. However, the program also lists an additional 76 infectious diseases. (Influenza is the second most likely diagnosis, with a probability of 8%.)

  • Think long and hard before deciding to meet up with friends or family. Your own health is a priority, and you want to be considerate of others, too.

    Contracting COVID-19 is a lot about the company you keep, explains Stephen Berger, MD, infectious disease expert and co-founder of GIDEON (Global Infectious Diseases and Epidemiology Network). But the places you go can make a difference, too.

    “Infectious material enters our body through our mouth or nose — either because you were within a few feet of a human carrier, or because something brought this material to the area of our face,” Dr. Berger says.

  • … if you want to make your voice heard at a protest, know that there are ways to lower your risk of catching—or spreading—COVID-19

    “Assume that the stranger standing next to you is spreading the virus,” adds Stephen Berger, M.D., infectious disease expert and founder of the Global Infectious Diseases and Epidemiology Network (GIDEON).

  • Science publications about COVID-19

    “The volume is so great that what’s being published on COVID is equal to all the other research that is usually being put on infectious disease as a whole,” says Uri Blackman, CEO of GIDEON Informatics, which has put out medical databases since 1992.

  • “Lavatories are, unfortunately, ideal for the transmission of COVID-19. They are closed and poorly ventilated,” says Stephen Berger, M.D., an infectious disease expert and co-founder of GIDEON, the Global Infectious Diseases and Epidemiology Network.

    “Urinals and sinks are crowded together, and partitions rarely extend upward to shield someone’s face. Although toilet stalls are isolated, droplets and aerosols will continue to linger there, several minutes after the last user has left,” he says.

  • “According to the Global Infectious Diseases and Epidemiology Online Network (GIDEON), as at 19 April there are 24 countries/territories that have not reported any cases of COVID-19. These are mostly small Pacific Island Nations, however also includes two countries in Europe – Tajikistan and Turkmenistan.”

  • “During the recent wave of protest gatherings, we’ve witnessed total abandonment of social distancing,” said Stephen Berger, an infectious disease expert and co-founder of the Global Infectious Diseases and Epidemiology Network (GIDEON).

    “The center of a large crowd is no different than a sealed off, unventilated room filled with potentially infected individuals – many holding large signs which will block the flow of clean air,” Berger told Yahoo Finance.

  • Experts say it’s possible we may see an increase in cases if people are unable or unwilling to physically distance.

    “The center of a large crowd is no different than a sealed off, unventilated room filled with potentially infected individuals — many holding large signs which will block the flow of clean air,” said Dr. Stephen Berger, an infectious disease expert and co-founder of GIDEON (Global Infectious Diseases and Epidemiology Network).

    “If even one carrier of COVID-19 was present at these gatherings, we can expect to see a wave of cases appearing during the next 2 to 14 days. Most will begin to experience symptoms 5 to 6 days after the event,” he said.

  • But you may be able to get COVID-19 through your eyes, as well. “Theoretically, the virus of COVID-19 could arrive to the eyes and travel down through our tear ducts into the nose and throat,” explains Stephen Berger, M.D., a double board-certified infectious disease specialist and microbiologist, and founder of GIDEON, the Global Infectious Disease and Epidemiology Online Network. This route of infection hasn’t been proven, but is suspected to be how some people get the virus.

  • Dr. Stephen Berger, an infectious disease expert and co-founder of the Global Infectious Diseases and Epidemiology Network (GIDEON), also stressed the importance of 6-foot spacing.

    He said a “large, open, and ventilated” space is preferred — outdoors, if possible.

    “Before dining in a restaurant, the big question to ask is, simply, ‘Do they adhere to social distancing?’” Berger told Healthline. “Before sitting down and asking for a menu, check to confirm that the restaurant staff is wearing masks, and that these masks cover their noses and mouths.”

  • But do gloves protect you from COVID-19?

    “There is no evidence that gloves can protect us from acquiring COVID-19,” says Stephen Berger, M.D, a board certified infectious disease and microbiology physician, and founder of GIDEON, the Global Infectious Disease and Epidemiology Online Network. “The modern version of surgical gloves was invented to prevent healthcare workers from passing infection to the patient,” he adds. So gloves are probably more effective at preventing you from passing the virus to others than they are at protecting you from it — similar to fabric face masks.

  • To estimate this risk, we must start by drawing maps: where are these species and how much are they in contact with human populations? This is the study project that Timothy Poisot initiates by combining mathematical models, artificial intelligence and ecology.

    To better understand these zoonoses—diseases that are transmitted from animals to humans—researchers drew data from the large epidemiological inventory of human diseases identified, the GIDEON database.

  • “Almost by definition, an exercise gym is swarming with objects and surfaces [that may] have been contaminated by other humans,” says Stephen Berger, MD, board certified in infectious diseases and clinical microbiology. “Repeated contact with workout machines, weights, etc., can transfer an invisible layer of bacteria, viruses and even parasites to our own skin and clothing.”

  • “Pathogens can be seen directly in specimens from the patient, often using a microscope, or grown in the laboratory over a period of days to weeks,” Stephen Berger, founder of the Global Infectious Diseases and Epidemiology Network, said.

    “In most viral infections, specific antibodies can be detected for months to years following infection — and in many cases well into old age,” says Berger.

  • “All three countries have a coordinated, nationwide, centrally planned response as well as travel restrictions, both domestic and international,” said Dr. Stephen Berger, a double board certified expert in infectious diseases and microbiology and the founder of GIDEON, the Global Infectious Disease and Epidemiology Online Network.

    In addition, Berger told Healthline that “both Vietnam and South Africa have been strictly enforcing their chosen policies with police and military involvement. New Zealand and South Africa have employed nationwide lockdowns.”

  • Stephen Berger, M.D., a board-certified infectious disease doctor and co-founder of the Global Infectious Diseases and Epidemiology Network (GIDEON), an online diagnosis and reference tool for infectious diseases and microbiology … [explains] “A gym is just another venue in which disease can be passed from person to person, and the risk of contracting COVID-19 might increase there, where group sports and games require close personal contact,” he explains. “The fact that you might be young and healthy won’t affect your chance of becoming [infected]; it will really only increase your chances of surviving an infection without severe or fatal consequences.”

  • “mobile phones are like international ambulatory five-star luxury hotels” for germs. In fact, he said, “no other type of everyday object can compete.”

    That point was seconded by Dr. Stephen Berger, co-founder of Global Infectious Diseases and Epidemiology Network (GIDEON) in Tel Aviv, Israel.

    “Cellular phones are ideal vehicles for the virus of COVID-19,” he agreed. “They are repeatedly exposed to material exhaled from our mouth and nose, and spend literally hours in our rather filthy hands. Viruses of this type are known to survive on plastics and stainless steel for two to three hours; on aluminum for two to eight hours, on cardboard and paper for up to 24 hours, and on ceramic or glass for up to five days.”

  • The answer here is: probably. Whether it’s safe or not depends largely on two things: where you live and the time you choose to go for a walk, says Stephen Berger, MD, a board-certified infectious disease doctor and co-founder of GIDEON (the Global Infectious Diseases and Epidemiology Network), an online diagnosis and reference tool for infectious diseases and microbiology.

  • Using the Global Infectious Diseases and Epidemiology Online Network (GIDEON) database, it was even possible to date the start of this increase of global outbreaks in rickettsial diseases in 1971.

  • I reached out to an expert in infectious disease, Dr. Stephen Berger. Berger is board-certified in both infectious diseases and clinical microbiology and is a co-founder of GIDEON, the Global Infectious Diseases and Epidemiology Network. Here are his insights into the connections between coronavirus and food. The interview has been condensed and edited.

  • “Masks should be as closely fitted to the skin as possible,” Dr. Stephen Berger, an infectious disease expert and co-founder of GIDEON, the Global Infectious Diseases and Epidemiology Network, tells PEOPLE.

    “The nose must be covered,” says Berger. “Note that when people are tested for the virus, a swab is inserted into the nose — because that is where the virus is!”

  • “We are all swimming through an invisible swamp of bacteria, viruses, fungi and parasites,” noted Dr. Stephen Berger, co-founder of the Global Infectious Diseases and Epidemiology Network in Tel Aviv, Israel. “Those bookshelves and those pictures on the wall are teeming with ugly microbes. Not to mention your cellular phone, wristwatch, eyeglasses and everything else in your world.”

  • 9. Realize that covering up your face is not an excuse to not social distance:  … “Extremely small particles, including the virus itself, might pass through the spaces that allow air to pass,” explain Stephen Berger, M.D., an infectious disease expert and co-founder of GIDEON, the Global Infectious Diseases and Epidemiology Network. He adds that facial coverings do not cover the eyes, which is another channel in which the virus can be transmitted. “And face masks do not protect our hands, clothing, objects that we may be carrying,” says Berger. “All of these are exposed to contaminated secretions and might infect us at some later time.”

  • “Some of the underlying reasons why COVID-19 may be more deadly for men than women may include the fact that heart disease is more common in elderly men than in elderly women,” Dr. Stephen Berger, an infectious disease expert and co-founder of the Global Infectious Diseases and Epidemiology Network (GIDEON), told Healthline. “Studies also find that high blood pressure and liver disease are more prevalent in men and these all contribute to more negative outcomes with COVID-19.”

  • Over 330 agents are used in the field of Infectious Disease, sold under more than 29,300 trade names worldwide. Drugs used against bacteria, parasites, and fungi take advantage of the biological nature of these organisms and disrupt their ability to grow and multiply, or utilize oxygen, sugars, proteins and other nutrients. Viruses, however, do none of these things – instead invading our cells and converting them into “factories” which produce yet more viruses. Thus, most drugs used against viral disease interfere with various stages of cell invasion or the interaction of viral DNA/RNA with the host cell.

    Status report: Drugs under study for the treatment of COVID-19, by Stephen Berger, MD, Journal of Public Health Management and Practice, 2020

  • In this edition of the Code Red Podcast, Allen Roth discusses the COVID-19 pandemic with infectious disease expert Dr. Stephen Berger. Dr. Berger is a co-founder of GIDEON, the Global Infectious Diseases and Epidemiology Network, and was the Director of Geographic Medicine and of Clinical Microbiology at Tel Aviv Medical Center. Board-Certified in both Infectious Diseases and Clinical Microbiology, his expertise gives valuable insight into the ongoing global pandemic. Dr. Berger also served in the United States Navy as a Medical Officer in the 6th Fleet.

  • The GIDEON is a Global Infectious disease knowledge management tool that maintains up to date information on the latest trends in epidemiology and treatment. All the information available through GIDEON is from sources that are peer-reviewed and backed by scientific evidence. The information available through GIDEON is collected from various sources including ProMED. The information is accessed and collated through a system of computer macros which includes a monthly search of PubMed against a listing of all GIDEON key words, and titles / abstracts of interest are reviewed. All available national Health Ministry publications [print and electronic] are scanned, as are standard publications of WHO and the US Centres for Disease Prevention and Control (US CDC). Additionally, relevant peer-reviewed publications are continually examined for relevant articles. The GIDEON database contained 119 events over the period 2016 to 2018.

  • Epidemiological data are rarely easily accessible or available in an easily analyzed format. There are efforts to circumvent these issues, such as Project Tycho and Gideon <…>.

  • … a recent study by Murray et al. delineated biogeographic regions based on the popular GIDEON dataset …

    Data from the Global Infectious Diseases and Epidemiology Network (GIDEON) contain pathogen outbreak information at the country level obtained from case reports, governmental agencies and published literature records.

  • <…>Notably, in 2017, dengue outbreaks were reported from eight Sub-Saharan countries reaching an excess of 21,000 total cases. Burkina Faso recorded more than half of these cases (13,135) including 28 deaths (Gideon, 2018).

  • … extracted the relevant data from GIDEON (Global Infectious Disease and Epidemiology Online Network, which contains information on the presence and occurrence of epidemics of human infectious diseases in each country as well as the number of surveys conducted in each country. This dataset is generally considered to be the most complete and up-to-date in the world and has been regularly used in previous comparative studies of pathogen diversity and epidemics.

  • The resource is intended for public health practitioners and specialists as well as educators and librarians. For the former, GIDEON serves as a tool for differential diagnoses and as a reference for treatment and epidemiological information. The reference functionality is useful to librarians, researchers, and educators.

    A Review of GIDEON, Doody’s Collection Development, 2018

  • One of the most powerful applications worldwide is the GIDEON system, which helps diagnose 337 specific infectious diseases in 224 countries. Its database covers 1,147 microbial taxa and 306 antibacterial agents and vaccines. The information it handles is updated weekly and includes more than 20,000 images, graphics, infographics maps, etc. All this allows you to reach 94% of correct diagnoses, and that is why it is one of the most used systems in the field of medicine.

    The most probable disease may be of little practical importance to the patient’s outcome. On the other hand, missing the diagnosis of a severe, albeit less-likely, disease on the differential diagnosis may have grave consequences.

  • As in the primary model, the mosquito-virus pair matrix was constructed based on the Global Infectious Diseases and Epidemiology Network database (GIDEON, 2016), the International Catalog of Arboviruses Including Certain Other Viruses of Vertebrates (ArboCat) (Karabatsos, 1985), The Encyclopedia of Medical and Veterinary Entomology (Russell et al., 2013) and (Mackenzie et al., 2012). This resulted in a dataset containing 180 mosquito species and 37 viruses, for a total of 334 vector-virus pairs.

  • Infectious disease data were obtained from GIDEON (Global Infectious Diseases and Epidemiology Network), which contains information on the presence of human infectious diseases and occurrence of epidemics in each country. This source has regularly been used in comparative studies of pathogen diversity [17], [20] or infectious disease outbreaks [10].

    Using the GIDEON database, and over the period from 1950 to 2008, 124 different diseases with epidemics were identified in Asia-Pacific countries. An increase in both the number of outbreaks and the number of different diseases causing outbreaks through time was observed.

  • A total of 347 infectious diseases of clinical importance were selected for review based on the GIDEON database, accessed November 2010. GIDEON is an infectious disease information and diagnostic resource available online through subscription that derives its content from a range of sources including formal peer-reviewed journals and informal sources such as Ministry of Health reports.

    Global mapping of infectious disease, Philosophical Transactions of the Royal Society B: Biological Sciences, 2013

  • Based on the Global Infectious Disease and Epidemiology Network (GIDEON), a global database including water-associated pathogens and diseases was developed.

  • Those searching for practical answers about causality, transmissible agents, disease etiology, global prevalence or current treatments might want to search GIDEON (Global Infectious Disease Epidemiology Online Network), an interesting “niche” information source targeting the research requirements of epidemiologists, clinical & translational researchers, MPH students, toxicologists or anyone interested in tracking or diagnosing infectious diseases on a country- or worldwide scale (subscription required).

    A search for causality or epidemiology done in the resources indexed by GIDEON is quite unlike a search done in PubMed about the etiology of Liver Cancer. The producers collect, review and index factual data collected from around the globe; their data encompasses a wide and diverse group of human cultures, agricultural, societal, economic or environmental practices.

  • GIDEON e-Books are an encyclopedia of infectious diseases across countries worldwide. They are continually updated and represent the only texts of their kind. They complement the excellent GIDEON on-line diagnostic tool and are a great addition to a library for those practicing infectious diseases, public health, global health, and even primary care.

  • The number of different pathogen species (pathogen richness) was retrieved from the Gideon database.

  • Every infectious diseases program should have a subscription to Gideon, Dr. Keystone said. Plug in the pertinent facts regarding a case and Gideon spits out the complete differential diagnosis, with the possibilities rank-ordered and accompanying treatment recommendations. Physicians can obtain a free 15-day trial through the website. “Gideon is probably the best geographic, computer-based, online program for infectious diseases that I know of. You don’t have to be smart to know everything about tropical medicine. If you’re looking for something to help you diagnose tropical diseases, this would be the one,” he said.
