Salivary IgG to SARS-CoV-2 after mild COVID-19
A team of researchers based in Stockholm, Sweden, has demonstrated that individuals exposed to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have antibodies for the disease up to nine months after acquiring the disease, even if they displayed only mild symptoms.
Concerns of COVID reinfection
Symptoms of SARS-CoV-2, the underlying agent for coronavirus disease 2019 (COVID-19), vary massively amongst populations of different age groups and health conditions. Most notably, people over the age of 60, and those with underlying health conditions – predominantly lung and autoimmune – tend to suffer worse than younger individuals. Older age groups especially suffer more fatalities and more serious afflictions.

White-tailed deer susceptible to SARS-CoV-2, finds study
White-tailed deer have been observed to be susceptible to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). They can also transmit the virus both through direct and indirect contact to one another, researchers find. The research paper is available to be read online in the
The origins of SARS-CoV-2, the underlying causative agent for coronavirus disease 2019 (COVID-19), are still unknown. Genome sequencing of the virus has so far provided evidence of an origination event in horseshoe bats. However, as no evidence can be found for direct bat-human transmission, it seems likely that COVID-19 was passed to humans through an intermediate animal host, as has been observed in previous coronavirus outbreaks.
