The risk of post-COVID-19 condition is lower after an omicron infection, after a fourth vaccination and if the person did not develop post-COVID-19 condition after the first infection. This is shown by a nationwide survey of almost 110,000 participants in the German National Cohort (NAKO Gesundheitsstudie) who were asked to provide information on long-lasting symptoms after a coronavirus infection and their infection and vaccination history. https://medicalxpress.com/news/2024-07-covid-condition-factors-impact.html Thu, 04 Jul 2024 10:00:01 EDT news639304767 Scientists still are not sure how neurological symptoms arise in COVID-19. Is it because SARS-CoV-2 infects the brain? Or are these symptoms the result of inflammation in the rest of the body? A study by Charité—Universitätsmedizin Berlin has now produced evidence to support the latter theory. It was published in the journal Nature Neuroscience. https://medicalxpress.com/news/2024-02-neurological-symptoms-result-sars-cov.html Fri, 16 Feb 2024 10:48:05 EST news627302881 Certain diseases transmitted from animals to humans could kill 12 times as many people in 2050 than they did in 2020, researchers have claimed. https://medicalxpress.com/news/2023-11-animal-to-human-diseases.html Sat, 04 Nov 2023 08:00:01 EDT news618227764 The risk of developing long COVID is significantly lower following an infection with the omicron variant than after an infection with earlier coronavirus variants. This was the finding of a study by University Medicine Halle, which was published in the International Journal of Infectious Diseases. https://medicalxpress.com/news/2023-09-covid-omicron-infection-re-infection.html Wed, 13 Sep 2023 13:35:26 EDT news613830919 Exposure to common cold-causing coronaviruses may contribute to pre-existing immunity to COVID-19, according to a new study involving a Rutgers research scientist. https://medicalxpress.com/news/2023-08-insight-covid-immunity.html Thu, 17 Aug 2023 15:05:32 EDT news611503529 Since the coronavirus outbreak, the number of young adults with moderate to severe chronic anxiety and depressive symptoms has increased sharply. In the year before the pandemic 16.7% of 18- to 24-year-olds suffered from moderate to severe chronic anxiety and depressive symptoms. They were experiencing these complaints in March 2019, November 2019 and in March 2020. In the year after the pandemic, this had increased to 21.4%. This translates to an increase of about 73,000 young adults. https://medicalxpress.com/news/2023-07-significant-chronic-anxiety-depressive-symptoms.html Mon, 10 Jul 2023 14:04:02 EDT news608216641 Researchers have developed a molecule that is, when administered nasally, extremely effective in preventing the disease caused by all known variants of the SARS-CoV-2 virus.

It is still unclear exactly how, when and where this virus originated. Now, a study published in the journal Science by researchers from Charité-Universitätsmedizin Berlin and a network of African institutions shows that omicron's predecessors existed on the African continent long before cases were first identified, suggesting that omicron emerged gradually over several months in different countries across Africa. https://medicalxpress.com/news/2022-12-deep-omicron-variant.html Thu, 01 Dec 2022 14:57:04 EST news589129021 The World Health Organization chief on Wednesday said a nearly 90% drop in recent COVID-19 deaths globally compared to nine months ago provides "cause for optimism," but still urged vigilance against the pandemic as variants continue to crop up. https://medicalxpress.com/news/2022-11-world-covid-deaths-february.html Wed, 09 Nov 2022 14:22:55 EST news587226173 Infection with the pandemic virus, SARS-CoV-2, can reduce the number of bacterial species in a patient's gut, with the lesser diversity creating space for dangerous microbes to thrive, a new study finds. https://medicalxpress.com/news/2022-11-covid-virus-infections-disrupting-gut.html Tue, 01 Nov 2022 09:43:04 EDT news586514581 In laboratory and primate tests, a new pan-coronavirus vaccine developed by the Duke Human Vaccine Institute (DHVI) has demonstrated wide protection against SARS-CoV-2 viruses and variants, including omicron BA.5. https://medicalxpress.com/news/2022-10-pan-coronavirus-vaccine-key.html Fri, 28 Oct 2022 09:26:56 EDT news586168004 On January 13, 2020, a paper touting the creation of a possible therapy that could be used to fight all known strains of the flu was published online. https://medicalxpress.com/news/2022-10-potential-therapy-derived-banana-protein.html Thu, 20 Oct 2022 14:53:03 EDT news585496381 "Smart surveillance" for viral spillover from animals to humans, targeted preparedness and drug and vaccine research, and worldwide cooperation on surveillance and stopping disease spread are required to reduce deaths and lessen the economic consequences of the next pandemic, according to an international team of scientists. https://medicalxpress.com/news/2022-10-pandemic-prep-smart-surveillance-viral.html Mon, 10 Oct 2022 15:00:01 EDT news584631337 A new study led by UC Davis Comprehensive Cancer Center researchers shows that current smokers have a 12% increased risk of a laboratory-confirmed viral infection and a 48% increased risk of being diagnosed with respiratory illnesses.

The authors trace this deadly resistance one hundred years back in history, to the rejection of sickly air called "miasma," the rise of germ theory and our own stubborn tendency to retain beliefs in spite of accumulating evidence to the contrary. https://medicalxpress.com/news/2022-09-historical-impeded-recognition-airborne-covid-.html Fri, 02 Sep 2022 13:47:24 EDT news581345240 Many patients suffering from an autoimmune disease such as rheumatism, ulcerative colitis or psoriasis must take medicine that affects their immune system. As the immune system also determines the effectiveness of vaccinations, some of those suffering from autoimmune diseases wonder whether it is safe for them to be vaccinated against SARS-CoV-2 without incurring any complications as a direct result of the vaccine, and whether the vaccine will be just as effective and offer them protection for the same period as time as healthy people. https://medicalxpress.com/news/2022-08-autoimmune-diseases-require-coronavirus-vaccination.html Mon, 22 Aug 2022 15:38:59 EDT news580401535 Why are bats often linked to incubating coronaviruses such as those behind COVID-19, SARS and other highly contagious respiratory diseases? https://medicalxpress.com/news/2022-07-pandemic.html Wed, 27 Jul 2022 16:28:07 EDT news578158082 President Joe Biden tested positive for COVID-19 on Thursday, is experiencing mild symptoms and has begun taking Paxlovid, an antiviral pill treatment. https://medicalxpress.com/news/2022-07-biden-covid-.html Fri, 22 Jul 2022 03:36:11 EDT news577679759 After staying home for more than a month, Chen Chunmei joined a long line of customers at a popular Beijing restaurant where diners tucked into massive bowls of crayfish following an easing of COVID restrictions in the Chinese capital. https://medicalxpress.com/news/2022-06-relief-caution-beijing-city-covid.html Tue, 07 Jun 2022 04:05:29 EDT news573793524 A top official at the World Health Organization said the U.N. health agency assumes the coronavirus outbreak in North Korea is "getting worse, not better," despite the secretive country's recent claims that COVID-19 is slowing there. https://medicalxpress.com/news/2022-06-covid-worse-north-korea.html Wed, 01 Jun 2022 16:17:52 EDT news573319069 A team of biophysicists reports that SARS-CoV-2 can withstand large physical forces, which could be one of the reasons for its success.
