Abstract
In June 2021, Udom et al. published their article in Transboundary
and Emerging Diseases performing a serological survey revealed evidence
of anti-N-IgG antibodies suggesting SARS-CoV-2 exposure in both dogs and
cats during the first and second coronavirus disease 2019 (COVID-19)
outbreaks in Thailand. Seroprevalence studies have proven an important
tool to monitor the progression of the COVID-19 pandemic. The duration
of immunity of SARS-CoV-2 is crucial for the course of the pandemic and
for this reason the monitoring of antibodies against SARS-CoV-2 is
important. The serum samples from different periods and regions were
valuable in terms of scientific significance for serological survey of
SARS-CoV-2 and emerging infectious diseases. In order to preserve the
remaining serum samples and ensure the stability of anti-virus
antibodies in storage serum samples, we strongly suggest that standard
serum banks should be established worldwide.
