Many governments, the UK included, focus their policy on physical distancing - which is the most obvious eye catching thing that filled the news about Wuhan. Contact tracing often gets far less attention - yet it is the absolute key to stopping this virus. It is also relatively easy to do. It doesn't need health workers. Other countries are using civil servants, community organizations and volunteers.

Contact tracing is the key to winning. Physical distancing is buying time, like defensive tactics in a game of football. Having bought time in this way we can go into the attack, crush this virus and eliminate it from our country.

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.

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.

Experts are weighing in on Matt Hancock’s proposal of “immunity passports ” in the UK. They say antibody tests will NOT prove you are immune to the disease. We don't know enough about this disease yet to say. From our experience with other diseases, it is possible that those with antibodies can be infected a second time (with the same strain of virus), and die of the disease.

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.

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 COVID-19 is not flu.

COVID-19 can be stopped; it can be contained. Any second wave can be stopped too.

You can totally crush COVID19. China, South Korea have shown how. Spain and Italy are doing it now too. The WHO say this with every press briefing but the media almost never report this. To do this you test, isolate and care for cases, trace contacts and quarantine the contacts.

If you stop 75% of the transmisions you change a transmission that goes

100 cases → 200 cases → 400 cases

to one that goes

100 cases → 50 cases → 25 cases

and it soon stops.
