WHEN Covid first emerged across the world, having a high temperature was a key sign you had the disease. But as the virus continues to mutate, the most common symptoms of the bug change too. A high…
"For the vast majority of people our defences have got pretty good at engaging with the enemy, that's why we don't see as much severe disease," he added.
"The UK population has been multiply vaccinated and very many people have also had an infection and this means that there is now significant immunity in the UK population." On January 16, 11 per cent of cases were accounted for by this new strain - formally known as XBB.1.5, data from the Global Initiative on Sharing Avian Influenza Data suggest.

Acute phase characteristics and long-term complications of pulmonary embolism in COVID-19 compared to non-COVID-19 cohort: a large single-centre study - BMC Pulmonary MedicineBackground To compare the severity of pulmonary embolism (PE) and the long-term complications between patients with and without COVID-19, and to investigate whether the tools for risk stratification of death are valid in this population. Methods We retrospectively included hospitalized patients with PE from 1 January 2016 to 31 December 2022. Comparisons for acute episode characteristics, risk stratification of the PE, outcomes, and long-term complications were made between COVID and non-COVID patients. Results We analyzed 116 (27.5%) COVID patients and 305 (72.4%) non-COVID patients. In patients with COVID-19, the traditional risk factors for PE were absent, and the incidence of deep vein thrombosis was lower. COVID patients showed significantly higher lymphocyte count, lactate dehydrogenase, lactic acid, and D-dimer levels. COVID patients had PE of smaller size (12.3% vs. 25.5% main pulmonary artery, 29.8% vs. 37.1% lobar, 44.7% vs. 29.5% segmental and 13.2% vs. 7.9% subsegmental, respectively; p | 0.001), less right ventricular dysfunction (7.7% vs. 17.7%; p = 0.007) and higher sPESI score (1.66 vs. 1.11; p | 0.001). The need for mechanical ventilation was significantly higher in COVID patients (8.6% vs. 1.3%; p | 0.001); However, the in-hospital death was less (5.2% vs. 10.8%; p = 0.074). The incidence of long-term complications was lower in COVID cohort (p | 0.001). PE severity assessed by high sPESI and intermediate and high-risk categories were independently associated with in-hospital mortality in COVID patients. Conclusion The risk of in-hospital mortality and the incidence of long-term complications were lower in COVID-19. The usual tools for risk stratification of PE are valid in COVID patients.
