After Receiving 1st Pfizer Injection, 2nd Pfizer Injection, Then 3rd Pfizer Injection, Testing Positive Overseas For Covid-19. The Following Adventure:

Returning to the United States this fulsome narrative might be of value.  After receiving 1st Pfizer injection, 2nd Pfizer injection, and then 3rd Pfizer injection, the following adventure:  

Day One
NEGATIVE Result. Nucleic Acid Amplification Test (NAAT). Quantitative Reverse Transcription PCR (RT-PCR). Combined Throat And Nose Swab (tested as received). Test targets the nucleocapsid gene (assay N1) and the envelope gene (assay E) of SARS-CoV-2.

Note from lab: “Please note that the SARS-CoV-2 assay does not target the ORF 1ab or S genes, our assay targets the SARS-CoV-2 N gene and E gene and the human RnaseP gene. There was no Ct value for N or E genes, and your RnaseP gene Ct value was 27.28.”

Day Four
POSITIVE Result. RT-PCR (NAAT) Test for SARS-CoV-2.
Viral Load HIGH. CT ORF 1ab: 23.9; CT N Protein: 22.6; CT S Protein: 24.3.
Average value of less than 25 is considered high, from 25 to 32 medium and above 32 low. Likely with the new Delta Plus variant, but that is not confirmed.

Note from lab: “Your request to know which strain of COVID you have in your positive result has been forwarded to me. Your results showed amplification in three genes which means that you likely had the original strain of COVID. The Delta strain does not amplify in S-protein. However, a definitive analysis would require genetic sequencing of your sample which is not a service that we offer commercially. (It would also cost you thousands of euros to perform).

Day Six
POSITIVE Result. RT-PCR (NAAT) Test for SARS-CoV-2. Viral Load was HIGH. CT ORF 1ab: 20.7; CT N Protein: 20.9; CT S Protein: 20.8. Was informed that the lower than previous test values is normal as the virus becomes more active in the body.

Day Six
IgG (ELISA) Post Vaccine And Post Covid SARS-CoV-@ IgG Antibodies (Immunoassay) test.
POSITIVE with Antibody Index of 24.08.

Day Fifteen
NEGATIVE Result. RT-PCR (NAAT) Test for SARS-CoV-2.
Viral Load in the sample NOT DETECTED.
CT ORF 1ab: N.A.; CT N Protein: N.A.; CT S Protein: N.A.

Day Fifteen
ELISA Test Results Report For SARS-CoV-2
SARS-CoV-2 [IgA/IgM] Antibodies (Immunoassay): 16.20 Antibody Index POSITIVE
SARS-CoV-2 IgG Antibodies (Immunoassay): 23.35 Antibody Index POSITIVE

CDC Provided Important Clarification With Answer To My Question 

CDC Internet Site:  If you recently recovered from COVID-19, you may instead travel with documentation of recovery from COVID-19 (i.e., your positive COVID-19 viral test result on a sample taken no more than 90 days before the flight’s departure from a foreign country and a letter from a licensed healthcare provider or a public health official stating that you were cleared to travel). 

CDC Internet Site: What kind of documentation of my test result or documentation of recovery do I need to present?  “Before boarding a flight to the US, you will need to show a paper or electronic copy of your negative test result for review by the airline and for review upon request by public health officials after you arrive in the US.  If you are traveling with documentation of recovery, you must present paper or electronic copies of your positive test result (dated no more than 90 days ago) and a signed letter, on official letterhead that contains the name, address, and phone number of a licensed healthcare provider or public health official, stating that you have been cleared to end isolation and therefore can travel. A letter that states that you have been cleared to end isolation to return to work or school is also acceptable. The letter does not have to specifically mention travel.” 

My Question To CDC: May my doctor in the United States provide the letter authorizing travel or does the doctor need to be in the country from which I will return to the United States? 

Response From CDC:  “If you are traveling with documentation of recovery, you must present paper or electronic copies of your positive test result (dated no more than 90 days ago) and a signed letter, on official letterhead that contains the name, address, and phone number of a licensed healthcare provider (either in the U.S. or abroad) or public health official, stating that you have been cleared to end isolation and therefore can travel. A letter that states that you have been cleared to end isolation to return to work or school is also acceptable. The letter does not have to specifically mention travel.”   

The CDC provided an important clarification that the “licensed healthcare provider or public health official” could be located in the United States- which may make the process for obtaining documentation less complicated and less expensive.  During my travel, I obtained documentation from my physician in the United States and from a physician in the country of departure.
