Though Saudi Arabia has a relatively low case rate of ~170 new cases per day, it has recently extended the travel ban over concerns of new variants.

Long Covid alarm as 21% report symptoms after five weeks

theguardian.com/society/2020/d…
"A fifth of people still have coronavirus symptoms five weeks after being infected, with half of them continuing to experience problems for at least 12 weeks, official data suggests, as concerns grow about the scale and impact of “long Covid”.

2/
"The study also reveals those admitted to hospital with Covid have higher risk of..cardiovascular events – such as stroke or heart attack, diabetes, kidney disease and liver disease, than matched controls with similar demographics and pre-existing conditions.

My 2020 thread of thanks and blessings.

Through this horrendous year, the one positive has been work with others who anticipate and act, who hear the suffering and cannot stand by. Superheroes, each with their unique strengths.

Due to the holiday season, reporting in many countries is largely influenced. Global daily increases are about 20% lower than the previous daily averages.

Italy reported the lowest since their recent peak, as the country begins vaccination.
Serbia reported 3,200 cases yesterday and has been decreasing for 3 weeks. The daily average dropped to one half of the peak.
Japan reported a new high for the fourth day in a row of 3,892 new cases. Tokyo and Kanagawa are both on rising rapidly, seeing double the amount of cases they were reporting three weeks ago.

Keep schools closed
The scientific evidence of multiple studies shows that students can be infected and infect others, and that outbreaks occur in schools.

2/
Because students are often asymptomatic (or particularly for young children perhaps are not reporting mild symptoms) standard testing protocols often miss their illnesses and contribution to transmission.

Travel restrictions are important, those countries that stop the new variants from achieving community transmission, or limit their extent, will benefit tremendously.
And if it was worthwhile to stop the current set of variants by travel restrictions a month ago, it is worthwhile to stop the next set that are arising now.

Why do many still adopt a static view?
Today we fight the next battle not the last one.

Choosing inaction today instead of fighting, we loose a round. We are harmed and the virus gains strength. The next round is harder.

Not fighting this round because we can't win the previous round is why we are losing
