According to the Paris Public Hospital Group, Louis-Mourier Hospital in the northwest suburbs of Paris admitted a patient with secondary infection with COVID-19 in January this year.
Later, the virus gene sequencing confirmed that the patient was infected with a variant strain of COVID-19 found in South Africa.
According to the notice, the patient soon developed into severe COVID-19 after admission and is still receiving treatment in the intensive care unit.
The public hospital group in Paris said that the patient’s condition was the first in France.
It is understood that the patient is a 58-year-old man with no major medical history.
He first contracted the novel coronavirus in September 2020, when he only developed fever and mild dyspnea. In December 2020, the patient tested negative for viral nucleic acid twice, so he was confirmed to be cured.
When he was admitted again in January this year, the man did not show immunosuppression and tested positive for COVID-19 antibodies.
The Paris Public Hospital Group believes that this indicates that the immunity to the novel coronavirus previously obtained by patients has not been able to avoid infection with the mutant strain found in South Africa.
On February 10th, local time, the intensive care team of Louis-Murier Hospital published the case report on the American Society of Epidemiology, Clinical Infectious Diseases.
Professor Ricard, the team leader, believes that the case is quite special and there is no definite explanation for its secondary infection and aggravated symptoms.
Therefore, the researchers called for a cautious attitude towards epidemic prevention and control until there is not enough scientific data to better assess the effectiveness of cross-immunization and vaccines for COVID-19 variants.
And even those who have been vaccinated or have contracted COVID-19 need to continue to comply with personal hygiene protection regulations
