In the bivariate logistic model, fever, headache, myalgia, abdominal pain, arthralgia, fatigue, dyspnoea, hypotension and haemoconcentration were statistically significantly associated with DENV-SARS-CoV-2-co-infected cases, and the laboratory findings including platelets, ALT, and AST were statistically significant with DENV-SARS-CoV-2 co-infections (Table 3). This evidence concerns the gene GPT and coinfection.
