The local epidemic of dengue in Guangdong is suspected to be triggered by imported cases and results in consequent seasonal transmission.

- The study aimed to investigate how long SARS-CoV-2 persists in body fluids and the immune response in COVID-19 infected individuals.
- Researchers analyzed viral loads and antibody responses in 35 patients from two hospitals in Guangdong, China, using various assays.
- Findings showed that severe COVID-19 cases had longer viral shedding in the nasopharynx and throat, early antibody formation, and high levels of neutralizing antibodies, particularly correlated with IgG and IgA.
We prospectively assessed 49 coronavirus disease cases in Guangdong, China, to estimate the frequency and duration of detectable severe acute respiratory syndrome coronavirus 2 RNA in human body fluids. The prolonged persistence of virus RNA in various body fluids may guide the clinical diagnosis and prevention of onward virus transmission.
