“These extraordinary measures of physical and social isolation are taking their toll,” said Emmanuel Sarmiento, general director of the Juan N. Navarro Children’s Psychiatric Hospital in Mexico City.
Anxiety about the pandemic was fueled Tuesday by an announcement from researchers in Hong Kong that they had identified what they said was the first confirmed case of COVID-19 reinfection, raising questions about the durability of immunity.
The patient, a 33-year-old man living in Hong Kong, tested positive in March but after two negative tests was found to be positive again in August.
Microbiologist Kelvin Kai-Wang To, lead author of the study, told AFP: “COVID-19 patients should not assume after they recover that they won’t get infected again.”
However experts were uncertain about the significance of the announcement, with some researchers saying the case could be extremely rare.
