New Study: How COVID-19 may trigger dangerous blood clots

Thu, 2020-11-05 12:06 — mike kraft

How COVID-19 may trigger dangerous blood clots | Science News Clots may stem from net-casting immune cells that, instead of fighting a coronavirus infection, capture red blood cells and platelets. Helen Thompson Science News

Some of COVID-19’s dangerous blood clots may come from the immune system attacking a patient’s body rather than going after the virus, a new study suggests.

ICN confirms 1,500 nurses have died from COVID-19 in 44 countries and estimates that healthcare worker COVID-19 fatalities worldwide could be more than 20,000

ICN confirms 1,500 nurses have died from COVID-19 in 44 countries and estimates that healthcare worker COVID-19 fatalities worldwide could be more than 20,000 The International Council of Nurses’ latest analysis shows that the number of nurses who have died after contracting COVID-19 is 1,500, up from 1,097 in August. The figure, which includes nurses from only 44 of the world’s 195 countries, is known to be an underestimate of the true numbers of deaths. ICN’s own analysis suggests that about 10% of cases globally are among healthcare workers.

New research points to potential link between pollution levels and Covid-19 death risk

Wed, 2020-11-04 17:34 — mike kraft

Research points to potential link between pollution and Covid-19 death risk A new study analyzed whether air pollution levels are associated with Covid-19 death tolls in more than 3,000 U.S. counties. Megan Thielking STAT

New research points to another potential factor that might play into a person’s risk of death due to Covid-19: prolonged exposure to high levels of air pollution.

In Arizona, the coronavirus raged. With masks and other measures, it subsided. What can it teach America? In Arizona, some jurisdictions are lifting mask mandates, fraying nerves among some observers who say such loosening is premature. Karin Brulliard, Jeremy Duda Washington Post

Age-specific mortality and immunity patterns of SARS-CoV-2

Mon, 2020-11-02 19:50 — mike kraft

https://www.nature.com/articles/s41586-020-2918-0

Estimating the size and infection severity of the SARS-CoV-2 epidemic is made challenging by inconsistencies in available data. The number of COVID-19 deaths is often used as a key indicator for the epidemic size, but observed deaths represent only a minority of all infections^1,2.

Additionally, the heterogeneous burden in nursing homes and variable reporting of deaths in elderly individuals can hamper direct comparisons across countries of the underlying level of transmission and mortality rates³. Here we use age-specific COVID-19 death data from 45 countries and the results of 22 seroprevalence studies to investigate the consistency of infection and fatality patterns across multiple countries.

We find that the age distribution of deaths in younger age groups (<65 years) is very consistent across different settings and demonstrate how this data can provide robust estimates of the share of the population that has been infected.
