From that last link above, the one from 2012...
...Ivermectin exerts its effect at a timepoint that coincides with the onset of intracellular viral RNA synthesis, as expected for a molecule that specifically targets the viral helicase...
Now let's fast forward, shall we, to a link from 2020...
Should We Try SARS-CoV-2 Helicase Inhibitors for COVID-19 Therapy?
I won't print the rest of what I'm thinking.
All you have to do is check the death rate in Nigeria…
Nonpharmaceutical Measures for Pandemic Influenza in Nonhealthcare Settings—Personal Protective and Environmental Measures
While this study came out in May 2020 (and the researchers were based in Hong Kong), it is actually a summary of 14 studies predating the pandemic, measuring the effectiveness of personal protective measures and environmental hygiene measures in nonhealthcare settings.
The bottom line - evidence from 14 randomized controlled trials of these measures did not support a substantial effect on transmission of laboratory-confirmed influenza. We similarly found limited evidence on the effectiveness of improved hygiene and environmental cleaning.
For me, the real telling point was from the ONE study, held in Cairo, where hand washing was correlated with lower incidence of influenza, but only when the subjects were children being subjected to sustained and overbearing statism:
An intensive campaign to promote hand hygiene was launched in the intervention schools to raise the awareness of students, teachers, nurses, and parents regarding the importance of hand hygiene and to increase the proportion of students washing their hands. Hand hygiene teams required students in the first 3 primary grades to wash their hands at least twice during the school day for ≈45 seconds, followed by proper rinsing and drying with a clean cloth towel.
Campaign materials were developed for 3 groups (students, teachers, parents). The teachers’ guidebook included a detailed description of the students’ activities and methods to encourage students to practice these activities. Posters were placed near sinks in the classrooms and on the playground. The primary message was to wash hands with soap and water upon arriving at school, before and after meals, after using the bathroom, and after coughing or sneezing.
Grade-specific student booklets were developed; each included a set of 12 games and fun activities that promoted handwashing. At least 1 activity was used each week. A special song to promote hand hygiene was developed and played regularly at schools. Informational fliers were distributed to parents to reinforce the messages delivered at the schools. Many schools were creative in motivating students to comply with washing hands, such as selecting a weekly hand hygiene champion, developing theater plays, and launching school contests for drawings and songs.
School Teams At each intervention school, a hand hygiene team composed of 3 teachers (social studies, arts, sports) and the school nurse was established. The hand hygiene team ensured that all predesigned activities for the hand hygiene campaign were implemented on a weekly basis (Table 1). The school nurses and teachers were trained to interview students, collect absenteeism data, interview parents, and complete data collection forms, and the nurses were trained to collect and process nasal swabs to test for influenza. At control schools, the nurses were supported by a single surveillance officer who was assigned to complete data collection forms.
Basically. hand washing works only if Big Brother is watching, threatening, and shaming you like a child..which is was what they tried.
They knew.
