The Rise and Fall of



The Coronavirus (SARS-CoV-2) was first seen in the United States at the end of January 2020.  In Michigan, we had very short peak of COVID-19 cases.  A COVID-19 case should be defined as a person who is infected with the Coronavirus and has symptoms.  A positive Coronavirus test is not the same as someone who has COVID-19. 

Since April, the death rate of Coronavirus has decreased by more than 80%.  Furthermore, the CDC has revealed that the true numbers of Coronavirus deaths in Michigan may be significantly fewer than those that are currently being listed.  This is due to the fact that all pneumonia deaths have been counted as Coronavirus deaths and people who have died of other causes were listed as dying of Coronavirus even though the virus may not have been the cause of their death.

Research and statistics have confirmed that the Coronavirus is almost never deadly to those under the age of 40.  Over the age of 40, most patients will fully recover from Coronavirus.  Those with significant underlying health conditions are at an increased risk for death or severe illness from COVID-19 illness. 

             Treatment with Hydroxychloroquine and Zithromax has been shown to be extremely effective in curing the disease in the vast majority of patients who have been treated with these medications. 

No one can predict whether or not there will be a rise in COVID-19 illness.  Certainly the number of positive tests is not at all indicative as to where we are with this virus as positive tests are often meaningless in someone who has no illness.  Furthermore, false positive results can occur with Coronavirus and this must be taken into account when looking at the statistics regarding this illness.

With almost ten months of experience with the diagnosis, treatment and management of Coronavirus patients, the United States has shown that this virus is no more dangerous than influenza.  Widespread testing of testing who are not ill does not seem to make sense as this virus has been shown to have very low risk of spread in asymptomatic carriers.  If you have any questions regarding the Coronavirus, please do not hesitate to contact me.  We have been putting out a newsletter periodically and depending on the state of the country and the virus, we will continue to do so in our office.  It is posted on our Facebook page.  We also offer this to be emailed.  Individuals who would like an email copy are invited to contact our office with their email addresses. 


A New Possible Treatment for Cat Allergy:


A new food additive for cats has been approved by the FDA which can decrease the amount of allergenic protein that is released by cats.  However, it remains to be seen as to whether or not this food additive will be of benefit in decreasing cat allergy symptoms in patients.  This food is packaged by Purina as Pro Plan LiveClear Allergen Reducing Cat Food.
