A study found that people who live in places where there are high levels of the atmospheric pollutant nitrogen dioxide had higher chances of ending up in intensive care units (ICUs) or of needing mechanical ventilation after they had caught Covid.

After the Covid pandemic began the need to call an ambulance for suicide-related issues increased, Australian researchers say.

Analysis of ambulance data between March 2020 and March 2021 found a significant and sustained increase in attendances for suicide attempts, suicidal ideation and self-harm compared to before the pandemic.

According to new data from the Centers for Disease Control and Prevention (CDC) published on Tuesday, sub-variants BA.4 and BA.5 now account for almost 13% of all new Covid-19 cases in the US between 29 May and 4 June, making up 5.4% and 7.6% of cases, respectively.
A week ago, both strains accounted for 7.5% of new cases and only 1% of new diagnoses in early May, reports the New York Times, though previous CDC estimates have been erroneous.

An updated version of Moderna’s Covid vaccine produces an eightfold increase in antibody levels against the Omicron variant, according to early trial results, raising hopes for a once-a-year booster to protect against the disease.
The vaccine is the first “bivalent” formulation to combine protection against Omicron and the original strain of coronavirus, and is the company’s leading candidate for upcoming autumn booster programmes.
Dr Paul Burton, Moderna’s chief medical officer, said the new vaccine raised antibody levels to such a degree that one booster a year could be enough, unless a substantially different variant calls for the vaccine to be redesigned again.

Kto ją otrzyma?Michał Dobrołowicz 13 czerwca (10:50)
Na przełomie września i października pierwsze osoby mogą dostać nową szczepionkę przeciwko Covid-19, dopasowaną do wariantu Omikron koronawirusa. Taki scenariusz przewiduje wiceminister zdrowia Waldemar Kraska.Nową szczepionkę w pierwszej kolejności dostałyby osoby, które skończyły 50 lat. Preparat byłby im podawany tylko jako dawka przypominająca.
Jednak osoby już po 50. roku życia ze względu na wiek, choroby współistniejące i naturalny spadek odporności powinny dostać tę dawkę przypominającą, żeby tę odporność na ten okres jesienno-zimowy wzmocnić - tłumaczy wiceminister zdrowia Waldemar Kraska
Europejska Agencja Leków, według informacji Ministerstwa Zdrowia, w najbliższych tygodniach może wydać rekomendację w sprawie czwartej dawki szczepionki dla osób w wieku 50+. Na razie prawo do niej mają seniorzy, którzy skończyli 80 lat.https://www.rmf24.pl/raporty/raport-program-szczepien-przeciw-covid/polska/news-nowa-szczepionka-przeciw-covid-19-kto-ja-otrzyma,nId,6089938#crp_state=1Air pollution got worse during lockdown in many countries, study findsRebecca Ratcliffe Tue 14 Jun 2022 15.20 BST

Photograph: Suvra Kanti Das/Zuma Press Wire/Rex/ShutterstockLockdowns imposed to stop the spread of Covid led to “virtually no change” in global average particulate pollution levels during 2020, and in some of the most populous countries pollution increased, according to a study.
Analysis of revised satellite-derived data on PM2.5 levels, which measure minuscule and dangerous airborne particles, suggests that the economic lockdowns imposed across many parts of the world brought clear skies to some areas only temporarily.

Research shows natural infection with Omicron doesn’t produce a strong immune response, so people can quickly become reinfected
According to ONS data, about 1 in 70 people in England were estimated to have Covid in the week ending 2 June. Photograph: Amer Ghazzal/Rex/ShutterstockIf you thought Covid-19 was dead and gone, think again. Early signs indicate that the UK may be at the start of a new wave of Covid infections driven by BA.4 and BA.5 – while new data suggests these variants may have evolved to refavour infecting lung tissue, which could make them more dangerous.
So what can we expect in the coming weeks and months?
Although BA.2 continues to account for the bulk of UK infections, data from the Office for National Statistics up to 2 June suggests that Covid cases may be starting to rise again in England and Northern Ireland, driven by an increase in BA.4 and BA.5 infections. The trends were uncertain in Wales and Scotland.

Report’s author says people died because US healthcare ‘leaves millions without adequate access to medical treatment’

Photograph: Mark Felix/AFP/Getty ImagesThe US could have saved more than 338,000 lives and more than $105bn in healthcare costs in the Covid-19 pandemic with a universal healthcare system, according to a study.
More than 1 million people died in the US from Covid, in part because the country’s “fragmented and inefficient healthcare system” meant uninsured or underinsured people faced financial barriers that delayed diagnosis and exacerbated transmission, the report states.
The US had the highest death rate from the virus among large wealthy countries and is also the only one among such countries without universal healthcare. It spends almost twice as much on healthcare per capita as the other wealthy countries, according to Kaiser Family Foundation data.

The Food and Drug Administration’s action follows its advisory panel’s unanimous recommendation for the shots from Moderna and Pfizer.
That means US children under five – roughly 18 million youngsters – are eligible for the shots, about 1.5 years after the vaccines first became available in the US for adults, who have been hit the hardest during the pandemic.
The FDA also authorized Moderna’s vaccine for school-aged children and teens. Pfizer’s shots had previously been the only ones available for those ages.

Eksperci we Włoszech ostrzegają, że latem może dojść do fali zakażeń koronawirusem z powodu szerzenia się kolejnego subwariantu Omikronu, łatwiej atakującego także osoby zaszczepione przeciw Covid-19. Przebieg choroby jest już jednak inny, objawy są lżejsze i trwają krótko - zapewniają, dodając, że nie ma powodu do alarmu. (...)

"O tym się nie mówi"21.06.2022 20:47 Katarzyna Gałązkiewicz
Podczas gdy w Polsce niewiele osób pamięta już o pandemii COVID-19, w niektórych krajach Europy i świata SARS-CoV-2 wywołuje kolejne fale zakażeń. Coraz więcej chorych odnotowuje się m.in. we Włoszech czy Wielkiej Brytanii, w której wzrosty są największe od grudnia. Lekarze apelują, by mimo zdjętych w kraju obostrzeń nie rezygnować z masek w przestrzeni publicznej oraz wykonywać testy, kiedy pojawią się objawy infekcji. Tym bardziej, że nowe podwarianty Omikrona BA.4 i BA.5 już dominują w Polsce. Niestety Ministerstwo Zdrowia w tej sprawie milczy. - W ostatnim czasie inne rzeczy absorbują opinię publiczną i o tym się nie mówi - ostrzega ekspert. (...)

Sensor tech can alert wearer to Covid early, helping to prevent onward transmission

Growing numbers of people worldwide use the devices to monitor changes in skin temperature, heart and breathing rates. Now a new study shows that this data could be combined with artificial intelligence (AI) to diagnose Covid-19 even before the first tell-tale signs of the disease appear.
“Wearable sensor technology can enable Covid-19 detection during the presymptomatic period,” the researchers concluded. The findings were published in the journal BMJ Open.

Podwarianty Omikronu BA.4 i BA.5 są cały czas obiektem badań naukowców. Zwłaszcza teraz, gdy liczba zachorowań w wielu rejonach świata ponownie wzrasta. Eksperci zwracają uwagę, że choć obecnie objawy COVID-19 nie odbiegają od tych, do których nas przyzwyczaił Omikron, to mogą pojawić się dwa, szczególnie niepokojące.1. Podwarianty BA.4 i BA.5 – co o nich wiemy?Podwarianty koronawirusa BA.4 i BA.5 wzbudziły zainteresowanie badaczy z uwagi na dodatkowe mutacje w domenie wiążącej wypustki receptora. Mówiąc wprost, oznacza to, że mogą być jeszcze bardziej zakaźne niż wariant pierwotny Omikronu. Dodatkowo lepiej sobie radzą z omijaniem odpowiedzi odpornościowej zarówno u ozdrowieńców, jak i zaszczepionych osób. (...)
