William Haseltine: People should regard everyone they meet as infected and act accordingly. ‘That’s the only safe assumption you can make. And don’t assume that if you’ve been infected, you’re protected.’

Colorado woman tests positive for COVID-19 twice

Less than two months after testing positive for COVID-19, and two negative tests, a Lafayette woman tested positive again.

LAFAYETTE, Colo — A month 1/2 since her first time contracting the novel coronavirus, a woman in Lafayette found out she tested positive for COVID-19 — again.

Michelle Hart first developed COVID-19 symptoms at the end of April. Doctors administered a Polymerase Chain Reaction (PRC) test — commonly performed with a nasal swab for coronavirus. On May 2, Hart's results returned positive.

Since then, Hart said her symptoms have "come and gone" and two consecutive negative coronavirus tests led her to believe she was out of the woods.

"Even though I was still having some symptoms, I was told that, you know, I’m not positive," Hart said.

But the persisting symptoms worried Hart enough to stop by an urgent care and ask for flu and strep tests. The results of both of those tests came back negative. So, Hart was given yet another nasal swab test.

On Wednesday morning, the antigen test showed Hart was carrying the virus.


Dallas Woman Tests Positive for Coronavirus Again After 4 Months: 'I Was Floored'

Doctors are unsure why the virus sometimes reappears — or if it is contagious the second time around. Meredith McKee first tested positive for the potentially deadly virus in February, diagnosed after feeling "clear and obvious" symptoms, she told NBC 5.

"I had a dry cough like you would not believe. It would not stop,” McKee recalled, explaining that she managed to fight off the first bout of the virus from home.

She even donated some of her plasma after testing positive for antibodies.

"I felt great finally [doing] something good coming out of the hell that I’ve been through because I'm going to help up to eight people with this plasma,” she said.

However, last week, McKee shared a tearful photo of herself from a hospital bed at Texas Health Presbyterian in Dallas. After admitting herself with high blood pressure and a headache on Friday, she found out she was one again positive for COVID-19 four months after her initial diagnosis. Doctors are not sure why the virus sometimes reemerges — or if it is contagious the second time around. Some experts say that a second positive test could just mean that the virus is taking its time to leave the body, but that it can't infect others.

"It's possible that people could shed remnants of the virus for some period of time. That doesn't mean anything is wrong with them or that they are contagious," Dr. William Schaffner, an infectious disease expert at Vanderbilt University Medical Center in Nashville, told NBC 5.

Similarly, Dr. Ania Wajnberg, associate director of medicine at the Icahn School of Medicine at Mount Sinai in New York City, told the outlet that they are finding that second positives are not strands of live virus.


Researchers in the US have reported the country's first confirmed case of coronavirus reinfection.

25-year-old man with no known immune disorders or underlying conditions was infected with Covid-19 on two separate occasions,

Dr Mark Pandori from the Nevada State Public Health Laboratory is the lead author of the new report on this.

The disease was more severe the second time.


Dutch woman, 89, dies after being infected with coronavirus twice

Recently, To et al. published a report of a 33-year old Hong Kong resident with a SARSCoV-2 reinfection, confirmed by whole-genome sequencing.[1] Here, we report a case of a reinfection, in an 89-year old Dutch woman, suffering from Waldenström’s macroglobulinemia, treated with B-cell-depleting therapy. She presented to the emergency department with fever and severe cough and a lymphocyte count of 0.4x109 /L. An in-house SARS-CoV-2 RT-qPCR (E-gen),[2] on a nasopharyngeal swab was positive (Cq 26.2). She was discharged after 5 days and besides some persisting fatigue her symptoms subsided completely.

Two days after a new chemotherapy treatment, fifty-nine days after the start of the first COVID-19 episode, the patient developed fever, cough, and dyspnea. At admission, her oxygen saturation was 90% with a respiratory rate of 40/min. The SARS-CoV-2 RT-qPCR on a nasopharyngeal swab was positive (E-gen; Cq 25.2). At days 4 and 6, serum was tested for SARS-CoV-2 antibodies, using the WANTAI SARS-CoV-2 Ab and IgM ELISA, both were negative. At day 8, the condition of the patient deteriorated. She died two weeks later.
