Snippet: As recommended by the WHO, a seroconversion or a 4-fold increase in the IgG titer in acute (ideally during the first week of illness) and convalescent serum samples can be used to confirm MERS-CoV infection. We thus analyzed if this criterion is also suitable for the diagnosis of COVID-19 [10]. There were 41 patients who were sampled during the first week of illness.

Document: As recommended by the WHO, a seroconversion or a 4-fold increase in the IgG titer in acute (ideally during the first week of illness) and convalescent serum samples can be used to confirm MERS-CoV infection. We thus analyzed if this criterion is also suitable for the diagnosis of COVID-19 [10]. There were 41 patients who were sampled during the first week of illness. As shown in Fig. 3B , 18 of the patients (43.9%) who were IgG negative at the first week seroconverted afterwards (in the observation period). Eleven patients (26.8%) were IgG positive for the first samples, and they eventually achieved a ≥ 4-fold increase in the IgG titer at some points later.
