Looking for...


Just sneakin' around....
...but can't seem to find, a chart or data that shows body temp vs when someone is infectious. Not infected, because you can assume that if you have a rising temp. At the point you can detect a rising body temp, are you already infectious? Earlier? Later?

Or maybe there just isn't enough data out there to track it this way....

We analyzed BT data in the de-identified database of COVID-19-suspected patients in Mount Sinai and its affiliated hospitals in the New York area as of May 3, 2020. A total of 9417 patients tested positive for the SARS-CoV-2 virus by RT-PCR detection. After excluding patients with missing temperature data (n = 1802), 7614 patients were included in the analysis (Table 1). Fifty percent had a BT > 37 °C on the initial presentation and 78.5% of patients developed BT > 37 °C during the course of the disease. The overall mortality was 16.9% with a median of 7 days to death from the initial presentation. As shown in Fig. 1a, higher BT at the initial presentation did not show a significant association to mortality. Importantly, patients presenting with BT ≤ 36 °C had the highest mortality (26.5%, P = 0.003 relative to 36 °C < BT ≤ 37 °C), and this became even higher when the analysis was restricted to those with BT ≤ 35.5 °C (44%), indicating low body temperature at the initial presentation is a marker of poor prognosis. Meanwhile, maximum BT during COVID-19 infection was significantly correlated with mortality rate (Fig. 1b). There was a significant increase in mortality for every 0.5 °C increase in BT, and the mortality was as high as 42% in those with maximum BT > 40.0 °C.
Our results indicate that only half of the patients with positive SARS-CoV-2 virus present with BT > 37 °C at the initial presentation. However, temperature elevation is common, and high maximum temperature during the course of SARS-CoV-2 infection was a significant harbinger of poor outcomes. In fact, one in three patients reaching a maximum BT above 39.5 °C died. This was approximately a 5-fold increase in mortality rate as compared to patients whose temperature never broke 37 °C. In contrast, almost half of the patients initially presenting with low BT (< 35.5 °C) died. Our results, therefore, suggest that poor BT control during the COVID 19 disease course is a marker of poor prognosis and BT can be used as an easily obtained prognostic indicator.
