some good estimates of current COVID-19 epidemiology
Good to know. This is testing against a H1N1 flu virus, but hopefully applies for COVID-19 too.
… Rapid treatment of the virus with hot water had little effect on the virus, reducing the titre by around two-fold, but prolonged incubation at 55°C abolished detectable infectivity. However, the addition of any of 1% bleach, 50% and 10% malt vinegar and 1%, 0.1% and 0.01% washing up liquid were all effective at rapidly reducing viable virus below the limit of detection, while a low concentration of vinegar (1%) was no more effective than hot water alone (Figure 1A). In contrast to the plaque assay results, most agents were ineffective at reducing the number of detectable genome copies as determined by RT-PCR, with only bleach having a significant effect (Figure 2A). The data for the plaque assays and RT-PCR assays are compiled in Tables S1 and S2. Thus, while a strong oxidizing agent such as bleach is effective at reducing both genome detection and virus infectivity, low pH and detergent are equally efficacious virucidal agents. These results also indicate that whilst vinegar and detergent disrupt the viral envelope proteins reducing infectivity, only bleach disrupts the viral genome.(Via Damien)
supposedly this is about “tuning in the era of containers”, but really it’s more about which metrics are usable for GC tuning with the newish java G1 garbage collector.
A week ago, Italy had so few cases of corona that it could give each stricken patient high-quality care. Today, some hospitals are so overwhelmed that they simply cannot treat every patient. They are starting to do wartime triage. Here’s the guidance for that.
