First cases of SARS-CoV-2 infection in dogs and cats in Thailand.

ABSTRACT: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused the coronavirus disease 2019 (COVID-19) pandemic in humans since late 2019. Here, we investigated SARS-CoV-2 infection in dogs and cats during COVID-19 quarantine at private veterinary hospitals in Thailand. From April to May 2021, we detected SARS-CoV-2 in three out of 35 dogs and one out of nine cats from four out of 17 households with confirmed COVID-19 patients. SARS-CoV-2 RNA was detected from one of the nasal, oral, rectal and environmental swabs of dog-A (15 years old, mixed breed, male dog), cat-B (1 year old, domestic shorthair, male cat), dog-C (2 years old, mixed breed, female dog) and dog-D (4 years old, Pomeranian, female dog). The animals tested positive for SARS-CoV-2 RNA from 4 to 30 days after pet owners were confirmed to be COVID-19 positive. The animals consecutively tested positive for SARS-CoV-2 RNA for 4 to 10 days. One dog (dog-A) showed mild clinical signs, while the other dogs and a cat remained asymptomatic during quarantine at the hospitals. SARS-CoV-2 specific neutralizing antibodies were detected in both the dogs and cat by surrogate virus neutralization tests. Phylogenetic and genomic mutation analyses of whole genome sequences of three SARS-CoV-2 strains from the dogs and cat revealed SARS-CoV-2 of the Alpha variant (B.1.1.7 lineage). Our findings are suggestive of human-to-animal transmission of SARS-CoV-2 in COVID-19-positive households and contamination of viral RNA in the environment. Public awareness of SARS-CoV-2 infection in pet dogs and cats in close contact with COVID-19 patients should be raised.

Project description:We investigated the first 152 laboratory-confirmed SARS-CoV-2 cases (125 primary and 27 secondary) and their 248 close contacts in Kisumu County, Kenya. Conducted June 10-October 8, 2020, this study included interviews and sample collection at enrolment and 14-21 days later. Median age was 35 years (IQR 28-44); 69.0% reported COVID-19 related symptoms, most commonly cough (60.0%), headache (55.2%), fever (53.3%) and loss of taste or smell (43.8%). One in five were hospitalized, 34.4% >25 years of age had at least one comorbidity, and all deaths had comorbidities. Adults ≥25 years with a comorbidity were 3.15 (95% CI 1.37-7.26) times more likely to have been hospitalized or died than participants without a comorbidity. Infectious comorbidities included HIV, tuberculosis, and malaria, but no current cases of influenza, respiratory syncytial virus, dengue fever, leptospirosis or chikungunya were identified. Thirteen (10.4%) of the 125 primary infections transmitted COVID-19 to 27 close contacts, 158 (63.7%) of whom resided or worked within the same household. Thirty-one percent (4 of 13) of those who transmitted COVID-19 to secondary cases were health care workers; no known secondary transmissions occurred between health care workers. This rapid assessment early in the course of the COVID-19 pandemic identified some context-specific characteristics which conflicted with the national line-listing of cases, and which have been substantiated in the year since. These included over two-thirds of cases reporting the development of symptoms during the two weeks after diagnosis, compared to the 7% of cases reported nationally; over half of cases reporting headaches, and nearly half of all cases reporting loss of taste and smell, none of which were reported at the time by the World Health Organization to be common symptoms. This study highlights the importance of rapid in-depth assessments of outbreaks in understanding the local epidemiology and response measures required.
