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…
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…
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…

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…
What Works Against SARS-CoV-2? Results of 19 Anti-Virals Screened In Vitro
19 drugs were screened by the U.S. Food and Drug Administration. A copy of their preprint report is at bioRxiv. The study has not been peer-reviewed and, therefore, should not guide policy or medical decision making. Covid-19 has claimed 228 thousand lives and infected at least 3.2 million people worldwide, according to the Johns Hopkins…
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 …
Camostat: An existing drug as potential Covid-19 treatment
Camostat is a potential drug for Covid-19 by blocking the entry of the SARS-CoV-2 through the ACE2 and TMPRSS2.
Covid-19 Spread with Air-conditioning
From January to February 2020, 10 people from 3 families were infected by Covid-19 after eating in an air-conditioned restaurant. Here is how it happened. The restaurant is 145 m². The tables were about 1 meter apart. There is an air-conditioned, as shown in the figure below, next to table C. An exhaust fan is…
Study Explains the Silent Spread of Covid-19
A study published at Oxford Academic gives a reason why millions have Covid-19 in more than 180 countries. In this study, the scientist compared the growth of the SARS virus and SARS-CoV-2 and the damage they cause in human lung tissues. They also measured the immune response of the lungs to both diseases. The SARS…
Will the Pandemic get Better with Warm Weather?
There is a widespread belief that warmer weather in the summertime will lower the number of Covid-19 cases. The reason is that the warm sun and humidity will kill the SARS-CoV-2 virus. The SARS-CoV-2 causes Covid-19 disease. This is what the National Academy of Sciences, Engineering, and Medicine report tried to answer. The paper is…
The Asymptomatic and Symptomatic Covid-19 are Equally Infectious
There are two studies in this article: the Ningbo Study and its reanalysis. The Ningbo Municipal Center made the Ningbo Study for Disease Control and Prevention. The purpose was to know how infectious is the new coronavirus infection. That new coronavirus infection is later known as the COVID-19 disease. The Ningbo study concluded that people…
