Thu, 2020-12-24 16:50 — mike kraft

What the data say about border closures and COVID spread Models estimate that travel restrictions worked early in the pandemic, but became less effective throughout the year. Smriti Mallapaty nature

As countries in Europe rush to close their borders to the United Kingdom to prevent transmission of a new — and potentially more transmissible — variant of SARS-CoV-2, research has estimated the effect of international travel restrictions on COVID-19 spread earlier in the pandemic.

Can Travel Bans Really Stop the Spread of Coronavirus Variants? Experts Are Skeptical

Wed, 2020-12-23 12:28 — mike kraft

LONDON — As nation after nation rushed this week to close their borders with Britain, the moves brought back memories of the way the world reacted after the coronavirus first emerged broadly in the spring. Most of those initial travel prohibitions came too late, put in place after the virus had already seeded itself in communities far and wide.

This time, with countries trying to stop the spread of a new, possibly more contagious coronavirus variant identified by Britain, it may also be too late. It is not known how widely the variant is already circulating, experts say, and the bans threaten to cause more economic and emotional hardship as the toll wrought by the virus continues to grow.

Pulse Oximeter Devices Have Higher Error Rate in Black Patients--New study

Wed, 2020-12-23 10:20 — mike kraft

Pulse oximeters are one of the most commonly used tools in medicine. The small devices, which resemble a clothespin, measure blood oxygen when clipped onto a fingertip, and they can quickly indicate whether a patient needs urgent medical care.

Health providers use them when they take vital signs and when they evaluate patients for treatment. Ever since the pandemic started, doctors have encouraged patients with Covid to use them at home.

But in Black patients, the devices can provide misleading results in more than one in 10 people, according to a new study.

Here’s What People With Allergies Should Know About Covid Vaccines

Sat, 2020-12-19 19:38 — mike kraft

Allergic reactions reported in two health workers who received a dose of Pfizer’s vaccine in Alaska this week have reignited concerns that people with a history of extreme immune flare-ups might not be good candidates for the newly cleared shots.

The two incidents follow another pair of cases in Britain. Three of the four were severe enough to qualify as anaphylaxis, a severe and potentially life-threatening reaction. But all four people appear to have recovered.
