(Inside Science) -- Imagine putting your hand in a pile of poop. It stinks and squishes. What do you do next?
Most likely, you'll scrub that hand with plenty of soap -- and you don't need public health officials or a germ theory of disease to tell you that's the right thing to do. But when you touch the handrail on an escalator, it's much harder to remember that you could be picking up coronavirus germs.

COVID-19: Why UK Is Ignoring WHO Advice - Key Differences Between UK's Simulated Flu And Real World Data
I am going to send this article to Allyson M Pollock, professor of public health and lead author of a recent paper in the British Medical Journal.
The paper is called Covid-19: why is the UK government ignoring WHO’s advice?.
The authors of this paper say that
The reasons why tracing was stopped, against WHO recommendations, have not been published.
The detailed reasons are not published but the paper that motivates the new policy has been published. I have written about this before but for the purposes of this article have followed up in more detail and I will focus this article on the paper itself.
I feel many people don't really understand clearly what contact tracing really is and why it is so effective for COVID-19. If they understood this better they might make wiser decisions. The WHO in every press briefing stress that this is the key to not just delaying the spread of COVID-19 but suppressing it and then stopping it - crushing it right down to no new cases a day.
During difficult times, we hope that everyone will pull together, keep calm, and work as a unit to ensure that society continues to run smoothly. Unfortunately, this is not always the case – as is particularly evident right now.
Many governments, the UK included, do not seem to fully understand how important contact tracing is for stopping the outbreak. They focus their policy on physical distancing - which is the most obvious eye catching thing that filled the news about Wuhan. But contact tracing is the absolute key to stopping this virus.
The WHO stress this over and over.
Some countries have got this message. But many countries still focus on physical distancing and only isolating cases that are already tested and found to have Covid-19. Many academics also focus their theoretical work on physical distancing.
They also sometimes quarantine all the people that the person is in the same household with, or they close the school they went to, or their work place.
Free Trade Has Created Greater Food System Sustainability - Lack Of Farmers Puts Wealthy Countries At Risk
Modern agriculture and free markets changed all that. A new study finds that as the world has increased its standard of living - there are fewer people in poverty than ever in history and it continues to drop fast - it can lead to concern about food system sustainability. As people get wealthier, they move out of rural areas and into cities, but as we have seen during the SARS-CoV2 panic, when 2 percent of people provide all of the food there is less food system stability. Unless there is a large free trade market.
UK's Isolation Period Of 7 Days For COVID-19 Is Too Short - WHO Advises Isolation To 14 Days After Symptoms Resolve
In the UK those who think they have COVID-19, including confirmed cases, isolate at home for 7 days after onset of symptoms. Matt Hancock, the health secretary, was confirmed to have COVID-19 a week ago. He has just come out of isolation after 7 days. See: Matt Hancock leaves week-long isolation period under UK's 'outlier' rules
This is radically different from the WHO isolation period. According to the WHO he is still infectious and could contribute to the spread of the disease. He should only leave isolation this early if he has two negative PCR tests 24 hours apart.
The correlation was created using 85,670 participants of UK Biobank and 5,819 individuals from three other studies, who wore accelerometers (e.g. Fitbit) which recorded activity levels continuously. They wore the accelerometers continuously for seven days which provides more accuracy than people who write how well they slept diaries.
UK's Antibody Certificates Would Not Prove You Are Safe From COVID-19 - And Herd Immunity Is Unproven For COVID-19
Experts are weighing in on Matt Hancock’s proposal of “antibody certificates” in the UK, and saying that antibody tests will NOT prove that you are immune from the disease. We do not know. It is possible that those with antibodies can still be infected, and die of the disease.
Such certificates would give a false sense of security. Especially for the general public, they could also encourage risky behaviour such as people deliberately trying to get COVID-19 in order to pass the test and get back to work - a fraction of those people deliberately trying to get COVID19 would need ventilators or would die.
This year, no one seems to know or care if a group of lawyers paid an intern to go through USDA pesticide data and did simple arithmetic to declare how 'toxic' fruit was unless the pesticides on it were made by their clients.
Up to one in five women will develop postpartum depression, a condition that can adversely affect the thoughts, emotions and functioning of mothers, as well as the mental health of their partners and children.
Adjusting to parenthood after delivery is challenging under normal circumstances, let alone in the midst of a global pandemic. Concerns about exposure to COVID-19, combined with physical distancing recommendations, can worsen depression and decrease access to the resources, such as health care and social supports, that women typically use to build resilience and promote recovery.
This is a conversation I had recently via text with someone who suffers from depression about the situation about COVID-19 in the UK. I hope my answers will help others with depression face this situation.
The main message is, don't give up - we can and will deal with this - pressurize our government to act and protect yourself and others by making sure you don't get it yourself.
On a personal level, this is how to protect yourself, and also the people around you who might get it from you - you can break those chains of transmission at least and prevent it spreading through you into your community.
The idea that COVID-19 can’t be stopped and has to go in waves is based on the idea that it transmits like flu.
But this disease is not flu.
It can be stopped; it can be contained.
The main reason that's possible is because.
- it is not airborne [except for certain medical procedures like intubation]
- though there are people without symptoms, there don't seem to be many asymptomatic cases - and asymptomatic cases don't infect others much.
The spread of this virus is driven by people that typically either have symptoms or are presymptomatic - they develop symptoms later.
As the COVID-19 crisis unfolds, Americans have been hearing a lot about an obscure but vast federal trove of emergency supplies, the Strategic National Stockpile.
Yet social isolation can be harmful as well. If you've ever watched the television show "Alone", you know even the ablest survivalist can crack under actual isolation in the wilderness. And families may regard it as too risky to visit right now.

CT-scans of three-million-year old brain imprints inside fossil skulls of the species Australopithecus afarensis (famous for "Lucy" and "Selam" from Ethiopia's Afar region) reveals that while Lucy's species had an ape-like brain structure, the brain took longer to reach adult size, suggesting that infants may have had a longer dependence on caregivers, a human-like trait.
