A recent UK study suggests that blood clots in the brain or lungs may explain some of the common symptoms experienced by people with "long Covid", including brain fog and fatigue. The study, which included 1,837 people admitted to hospital due to Covid, found that two blood proteins, fibrinogen and D-dimer, were associated with cognitive problems. It is estimated that 16% of these patients experience difficulties with thinking, concentrating, or remembering for at least six months.
hough case reporting doesn't accurately reflect COVID-19 activity because of decreased testing and reporting, the number reported over the past month increased by 63%, with increased cases reported in three regions, the World Health Organization (WHO) said in its latest weekly update yesterday. ...
Only six sequences of BA.2.86 have been reported in four countries, but epidemiologists are worried they could represent many more because worldwide monitoring of variants has dropped off.
The newly identified variant has many genetic mutations and is distant from BA.2, its likely ancestor, and currently circulating XBB variants. The similarity of the sequences so far—six samples from four countries—suggests relatively recent emergence and rapid growth, but the HSA said it has low confidence in that assessment, pending the examination of further sequences.
COVID hospitalizations and death rose last week, along with other indicators and the proportion of newer Omicron variants such as EG.5, the Centers for Disease Control and Prevention (CDC) said in its latest data updates.
