High Levels of COVID-19 Antibodies is Bad News

Antibodies are usually associated with a healthy immune system fighting an infection. That’s mostly true, but there is a saying from Paracelsus, The Dose Makes the Poison. Anything in excess can be poisonous. Too much food, water, coffee, sugar, or mostly too much of anything are unhealthy. It is the same with antibodies against COVID-19….

CD4+ Cross-Reactivity between Seasonal Coronavirus Colds and COVID-19

A previous article, Antibodies to COVID-19 can Exist in the Uninfected, talked about research from the Francis Crick Institute about how the antibodies formed against seasonal coronavirus infections can protect against the new coronavirus infection COVID-19. Aside from antibody production, the body’s adaptive immune system has other components in its armory. One of which is the…

Antibodies to COVID-19 can Exist in the Uninfected

Is there a natural way to be immunized against COVID-19? Read on to know the answer. Four human coronaviruses (HCoV) are responsible for 30% of the seasonal colds. They are  HCoV-OC43, HCoV-HKU1, HCoV-NL63, and HCoV-229E.  The death rate associated with these seasonal colds is minimal compared to COVID-19. COVID-19 is different. It has a higher…

Sugar Increases Blood Pressure, Weight, Worsens Diabetes and COVID-19 Outcomes

According to the CDC, among U.S. adults, 29% have hypertension, 42.4% are obese, and 10.5% have diabetes. Prediabetes, the condition where the blood sugar is above normal but not high enough to be type 2 diabetes, is present in 88 million Americans or 1 in 3. Hypertension, obesity, and diabetes increase the risk of death…

Study: Current COVID-19 Test by the CDC is Wrong Half the Time

A study published in the July edition of the International Journal of Geriatrics and Rehabilitation looked into the accuracy of the current COVID-19 test issued by the CDC. The study retested the samples provided by the Connecticut State Department of Public Health with a second test. The first test was done using the CDC RT-PCR…

Who, Where and What can get you infected with COVID-19?

People who have asymptomatic COVID-19 are more likely to contaminate surfaces and spread COVID-19. That was one of the findings of a preprint study released in BioRxiv. The study examined asymptomatic, mild, and moderate cases of COVID-19 and different places, 641 environmental surfaces, and air samples. The presence of the SARS-CoV-2 virus was tested with…

The Rise and Fall of Antibodies in Mild and Asymptomatic COVID-19

A preprint study in biorxiv shows that not all who have asymptomatic and mild Covid-19  develop protective antibodies developed against  COVID-19. As a brief background, after exposure to a virus or bacteria, whether natural or by vaccination, the immunoglobulin M (IgM) rises, followed by immunoglobulin G (IgG). Immunoglobulin is the technical term for the antibody…

A Sustainable Way to Decontaminate a Face Mask Using Household Materials

The Total number of COVID-19 is much Higher

As of date, the total number of COVID-19 cases worldwide is more than 12 million. COVID-19 is most commonly detected with a nasal or throat swab. If there are enough SARS-CoV-2 viral particles that are in the lining of the nose or the throat, then the test becomes positive. However, after a few weeks, the…

Michigan Study Shows Lower Mortality Rates with Hydroxychloroquine and Azithromycin

A new study published in the  International Journal of Infectious Diseases shows that the combined use of hydroxychloroquine and azithromycin lowers the mortality rate of hospitalized patients diagnosed with COVID-19. The study was done at Henry Ford Hospital System (HFHS) Detroit, Michigan. The (HFHS) is a large six-hospital integrated health system. It includes an 802…

Protective Antibodies Against Coronaviruses are Short-Lived

A common belief is that once you get exposed to the COVID-19  virus, then a long-lasting immunity will develop, and there will be protection against COVID-19. That may not be the case. Two preprint studies, from Wuhan, China, and Amsterdam answers those questions. In both studies, the IgG or immunoglobulin G was tested. IgG confers…

Are People Who Test Positive Again for COVID-19 Still Infectious?

A reader, CSG, asked me a question. She knew someone who became ill and tested positive for COVID-19. That person has since recovered and asymptomatic. The problem is the repeat nasal swab after 2 months is still positive. Because of the positive repeat test, it is believed that the person is still infectious and so…

Hydroxychloroquine Lessens Mortality in Severe COVID-19 but Monitor the QT

A preliminary study from Gautret from France showed that the combination of hydroxychloroquine and azithromycin lead to a significant reduction of SARS-CoV-2 viral load in a small number of  COVID-19 patients.  A study from Tongji Hospital, Shanghai Institute of Materia Medica, and Shanghai Institute of Advanced Histochemical Studies in China published a new study showing that hydroxychloroquine…

Diabetic Complications, Pancreatitis, and COVID-19

The pancreas is an organ inside the abdomen that is located right behind the stomach. It is essential for life as it produces digestive enzymes and hormones. Without the pancreas, proteins, fats, and carbohydrates will be hard to digest. Insulin and glucagon come from the pancreas. In the absence of these hormones, blood sugar control…

NHC Inhibits SARS-CoV-2 and other Coronaviruses in Human Respiratory Cells and Mice

A ribonucleoside called NHC is a promising drug against COVID-19. It was studied by a collaboration of the University of North Carolina at Chapel Hill, Emory University, Vanderbilt University,  Drug Innovation Ventures at Emory (DRIVE), and the CDC. The study was published recently in  Science Translational Medicine. In the study, NHC is in the form…

How Long do Covid-19 Patients Get Hospitalized?

The duration of Covid-19 hospitalization is longer than average. This article is from a study of 420 Covid-19 patients hospitalized at  Shenzhen Third People’s Hospital in Shenzhen China, from January 11 to March 10, 2020. The 3 classes of Covid-19 based on symptoms Among the 420 patients, 23 or 5.5% were clinically mild. 394 or …

Covid-19 Antibodies

In an infection, the body mounts an immune response. One of the ways is by the production of antibodies or immunoglobulins (Igs). There are five kinds of immunoglobulins or Igs: G, A, M, D, and E.  IgM and IgG are tested for Covid-19. The IgM usually shows up first, followed by the IgG. COVID-19 antibody…

5 Spike Protein Blocking Drugs Under Research for COVID-19

The article, How the Covid-19 Virus Tricks the Human Cell, talks about how the SARS-CoV-2 virus can attach to human cells using the receptors on the cellular surface. Once connected, the virus can enter the cells, multiply and cause cell and organ damage. Using that knowledge, a drug that can block the  S protein from attaching…

How the SARS-CoV-2 Virus Tricks the Human Cell

Viral infections start with the entry of viruses into the cells. This article describes how the SARS-CoV-2 tricks the human cells to let it in. This updated article was first published on April 23, 2020 The SARS-CoV-2 virus causes Covid-19. That virus has now infected almost 19 million and killed more than 700 thousand worldwide. The…

How Far Can a Sneeze Go?

The current CDC recommendation for social distancing is 6 feet or 2 meters. The thought is that at 6 feet, the droplets from coughing or sneezing would land on a surface and prevent the spread of Covid-19. The 6-feet length may have come from a study about the Severe Acute Respiratory Syndrome or SARS epidemic…
