Don't Get Sick!
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…
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…
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…
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…
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…
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…
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…
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 …
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…
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…
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…
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…
All organs need an adequate blood supply all the time. To ensure a healthy blood flow, the endothelium or the blood vessels’ inner lining needs to stay healthy. Smoothness, elasticity, and the ability to repair itself and prevent unwanted blood clot formation are qualities of a healthy endothelium. Read: The Magical Endothelium As people get older…
Camostat is a potential drug for Covid-19 by blocking the entry of the SARS-CoV-2 through the ACE2 and TMPRSS2.
The Covid-19 virus is well known to cause pneumonia. However, it can also attack some other organs. Those susceptible organs have something in common that allows the SARS-CoV-2 virus to attack them. The SARS-CoV-2 virus causes Covid-19. One way the virus can enter a cell is if that cell has an ACE2 receptor. ACE2 stands…
A scientific brief from the WHO has announced that SARS-COV-2 can be transmitted airborne under certain conditions. Airborne transmission of the virus can occur in health care settings where specific medical procedures, called aerosol generating procedures, generate very small droplets called aerosols. Some outbreak reports related to indoor crowded spaces have suggested the possibility of…
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…
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…
Latest Articles: Covid-19 Spread with Air-conditioning Study Explains the Silent Spread of Covid-19 What Should Happen Before the Lockdowns are Relaxed? COVID-19 Headlines 7 pm EST update. An increase of 35,772 cases and 2,551 deaths. Case fatality rate still going up at 6.86% Contamination at CDC lab may have caused delays in rolling out coronavirus…
A lockdown is a tool for epidemic control. Movement and gatherings are controlled. Work, schools, and social groups are suspended to limit the spread of the SARS-CoV-2 virus. A lockdown cannot go on forever. Lockdowns can have psychological, social effects, and severe economic effects. That is why it has to end sometime. One significant advantage…
