You may have heard that people with diabetes are at a higher risk of contracting COVID-19. This is not the case. The truth is, people with diabetes are more likely to experience severe illness, long lasting effects, or even death if they are infected with COVID-19.
What We Know about Diabetes and COVID-19
In May, a nationwide multicentre observational study called the CORONADO study, observed the mortality risk in people with diabetes who were hospitalized for COVID-19. The study population was 88% type 2 diabetics and 12% type 1 diabetics. What they found was that one in ten diabetic patients hospitalized with COVID-19 died within seven days of hospital admission. One in five died within the first 28 days.
How Can We Improve These Numbers?
The flu is a respiratory infection caused by a group of viruses. Symptoms range from mild to severe and most commonly include body aches, cough, fever, headache and sore throat. The flu is contagious, spreading through tiny droplets from a cough, sneeze or even talking. We hear about it every year in the fall and winter because the viruses tend to survive longer in those seasons.
The flu vaccine is created to protect against influenza strains A and B. Once an individual is vaccinated, the body’s immune system responds by developing antibodies that will be ready to combat future infection. It takes about two weeks after a person has been vaccinated to gain protection. It is not unusual to briefly experience mild fatigue and muscle aches soon after injection as this represents an appropriate immune response, but because the ingredients in the flu shot have been inactivated, it is not possible to get “the flu” from the vaccine.
The flu vaccine is recommended for most people over six months of age and is given every year because:
The Circulating Flu Viruses Change
Influenza viruses undergo structural antigenic change and even mutation. Each February, flu experts gather and review the data to best decide what strains are predicted to circulate in the Northern Hemisphere during the upcoming flu season. Once the top 3 or 4 strains are identified, the viruses are grown then the vaccines manufactured using varying methods to create the safest and most effective flu shot. Typically, there is at least one and usually more than one new strain coverage included each year.
Immune Protection Declines Over Time
Over time, the antibodies created in response to that year’s vaccine begin to lose their effectiveness, though some individuals who received annual flu shots over many years maintain reserve immunity capable of preventing or softening the blow of a new infection even if challenged with a novel strain. The CDC recommends a yearly flu shot around October. Another advantage to getting the flu shot is that you are less able to carry and spread the virus to others that may have an altered immune status. Due to the fact older individuals don’t mount as robust of an immune response following vaccination, it is especially important for those over 65 years old to get the vaccine annually.
The CDC estimated that in the 2018-2019 flu season there were approximately 490,600 hospitalizations and 34,200 deaths from the flu. It’s safe to say the flu is a dangerous but preventable illness. We thank all volunteers that have contributed to now FDA approved and currently enrolling flu vaccine programs. Your participation has helped to save lives.

There are five forms of antibodies that the human body makes. There are two forms that are relevant for COVID 19, Igm and IgG.
Igm is a big molecule, which is the first molecule that your body makes when you are exposed to a particular antigen or virus. This is an acute phase type of antibody.
IgG is a long-term antibody that has memory for your immune system and also protects you long-term. The actual length of long-term protection is not known.
Typically, when you have antibody testing, you are tested for both Igm and IgG. These tests are not perfect. If someone tests positive for Igm but not IgG, we’re not sure if they are protected.
If someone has no Igm antibodies and lots of IgG antibodies, they’re likely protected due to the long-term memory of IgG.
The length of time the antibodies remain detectable following an infection is not known.
Our mission at ENCORE Research includes educating our community about health care news, particularly when standard media sources sensationalize the news. The coronavirus or COVID-19 story falls into this category. Patients and family members are asking, “How worried should we be?”
Our simple advice, “Don’t panic, but take sensible precautions.” Recent data, often reported incompletely, support the idea that we should think about COVID-19 as a bad strain of the flu.
New viruses are scary. Will these pathogens lead to minor nuisance illnesses like the common cold or horrible consequences like EBOLA, which kills nearly 90% of its victims? … or be more like the flu? Most people can understand and calibrate the severity of a virus based on their experience with the flu. Over the last decade, based on Center for Disease Control (CDC) statistics, the flu infects between 3-15% of all Americans each (mostly winter) season. Between 1 and 2% of flu victims require hospitalization and between 0.1 and 0.2% of victims die of complications of the illness. Death from the flu occurs mostly in infants, the very old and in folks with immune deficiency or other significant chronic illness.
For COVID-19, the initial reports of death rates of 4% in China and 10% in Iran now appear to reflect poor reporting (local officials and our media) and selective testing of patients. To make an accurate estimate of a death rate you need to know the total number of tests administered (which the media doesn’t typically report) to get a sense of whether all of the positive + tests are being captured. Otherwise, the death rate reflects what happens only to the sickest patients, those already on death’s door when they receive testing, rather than the full spectrum of disease.
As of this past weekend, we have good data to review to help us understand the true death rate of COVID-19. As of March 2, in South Korea, a hard hit country with a good healthcare system, the death rate is 0.51% (< 1%). South Korea has deployed extensive resources for testing of coronavirus. South Korea has now reported 22 deaths occurring among 4,335 patients infected by COVID-19 out more than 100,000 patients tested. The large number of tests and the relatively low number of positive tests helps us feel confident that South Korea has identified most patients with the illness, an essential part of the equation needed to determine the true death rate.
The South Korean death rate likely reflects a maximum rate of death. We suspect that the death rate will be lower in the US since we have had more warning and will intervene earlier with antiviral medications and support.
The low death rate is good news. Unfortunately, this good news has a down side. Because of the mild illness that results from infection in most folks who contract it, COVID-19 will likely spread extensively before it winds down. Ironically, there is a tradeoff between viral spread and lethality. The worst viruses, like EBOLA, kill most infected people, but do not spread widely because people get sick quickly and have far fewer contacts. With the flu or COVID-19, people may have minor symptoms that allow them to function in society and spread the virus. Governor DeSantis of Florida announced the first confirmed cases in the state on Sunday (March 1) and more cases will certainly occur, probably many more cases.
Another part of our mission at ENCORE involves helping to get new medical therapies to patients. We participate as an active research site in the medical product development system. We have already received contact about our ability to test a coronavirus vaccine in healthy patients wishing to avoid illness. These studies focus on prevention. We have assured the manufactures of the vaccines that we are poised and ready to jump in for the clinical study.
Many antiviral drugs “sit on the shelves” of pharmaceutical companies that have had proven efficacy against the SARS and MERS viruses – similar in structure but more deadly than COVID-19. We have no reason to believe that some of these drugs will not work against COVID-19, but they remain untested. At this time, since we do not have any patients with COVID-19 at our clinics, we will not participate in the treatment studies. However, if things change, we will respond.
So, what to do now?
If you would like to be on standby as a volunteer for a healthy patient vaccine study let us know. Contact – 904-730-0166 or Jaxresearch.com. In the meantime, wash your hands like crazy, keep hand sanitizer in the car and/or office, and use it at least 5 times a day during cold and flu season!

Chikungunya (chik·un·gun·ya) virus or CHIKV is an infection spread by a two types of Aedes mosquitoes, the yellow fever and Asian tiger species. These are the same mosquitoes that transmit Dengue and Zika virus. The name “chikungunya” derives from the Tanzanian word meaning “to become contorted”, and describes the stooped appearance of sufferers with joint pain. The virus is spread when a mosquito bites (feeds on) an infected individual then passes it on to a non-infected person on a subsequent bite. The Asian tiger mosquito has gradually become the dominant species in the US and is recognized for its ability to survive colder temperatures, therefore posing risk for infection spread into Florida and southeast USA. In 2019, Chikungunya virus infections were identified in 26 US states.
Most patients who become infected develop high fever and joint pains within approximately a week. The severity varies but some patients experience debilitating aches which continue for years. The pain is caused by the immune system attacking itself causing inflammation of the tissue. Other symptoms of CHIKV viruses include:
Rare complications can occur. Infants and elderly adults are at highest risk for:
Prevention methods include:
There is currently no antiviral therapy approved for Chikungunya. Treatments are focused on helping to relieve symptoms and spread.
Due to public health concerns over the potential for disease outbreak, the FDA granted “Fast Track” status in 2018 for development of the first effective and safe vaccine to prevent virus spread.

You may have heard of the respiratory syncytial virus, in fact most people encounter RSV more than once, sometimes within the same year. Throughout older childhood and most of adulthood you may catch RSV during the winter and experience symptoms similar to the common cold. Symptoms range from mild to severe and include nasal congestion, cough, fever, wheezing, lethargy, and difficulty breathing.
It’s known that RSV shows severe symptoms in infants. However, recent studies have seen an increasing percentage of infected older adults with severe respiratory complications requiring hospitalization and occasional fatality.
As we age, we encounter a natural degradation of our immune systems. While you may have encountered RSV in the past, infection after 65 years of age could entail severe respiratory complications as the immune system loses its ability to fight the virus. Studies show that RSV causes approximately 170,000 hospitalizations and around 14,000 deaths per year among older adults.
There is currently no vaccine for the prevention of RSV, and because it’s a virus, antibiotics do not work. There are some treatments available, though usually pricey and used in extreme cases if you are already hospitalized.
The good news is there are several new preventative vaccines currently being developed. As an ENCORE Research community member, you have access to our cutting-edge research trials and are the first to know about new research.
