Researchers suggest that a routine TB vaccine for children in countries with high rates of bacterial disease could help reduce deaths from Covid-19.
After taking into account the differences in factors that may affect vulnerability to the coronavirus – such as income, education, health services and age distribution – the scientists found that countries with higher rates of Bacille Calmette-Guarin (BCG) tuberculosis vaccinations had Covid mortality rates19.
A good example was Germany, which had different vaccine plans before East Germany and West Germany were unified in 1990, according to the researchers. Mortality rates of Covid-19 among the elderly are almost three times higher in western Germany than in eastern Germany, where more elderly people received the vaccine as infants, they found.
Interim President of Bolivia, Áñez, positive for Covid-19 as the country’s economy and workers struggle
The Interim President of Bolivia said that she had tested positive for the coronavirus. Jeanine Áñez announced the news in a video posted on Twitter, saying that she would remain in quarantine for 14 days before taking another test. She is the second South American leader to test positive in recent days, after Brazilian Jair Bolsonaro announced his positive results on Monday. The economy and workers of Bolivia were hardly affected by the pandemic, as FRANCE 24 journalists in the field show.
Masks, beers and 2m tours: life in a nursing home after a coronavirus epidemic
In April, St Ronans’ nursing home in Southsea, Portsmouth tested positive for coronavirus. Without readily available tests, staff believe that Covid-19 has infected approximately 25 of its residents. Four died with symptoms or suspected symptoms. Through a mix of videos made by homeworkers and interviews filmed outside, they discuss how they are coping with the pandemic and how staff, residents and loved ones are coping to the “new normal”.
The results were reported Thursday in the scientific journal Proceedings of the National Academy of Sciences.
Study co-author Luis Escobar of Virginia Tech said in a press release that BCG vaccines have been shown to protect against other viral respiratory diseases. Dr. Escobar warned that the new findings are preliminary. The BCG vaccine is currently being tested to prevent Covid-19 in healthcare workers.
The study comes as new evidence emerges that severe Covid-19 has persistent sequelae. Almost 90% of Covid-19 convalescent patients discharged from a Rome hospital still had not returned to normal on average two months after falling ill, the researchers said.
Doctors studied 143 adults hospitalized on average for two weeks. Most were diagnosed with pneumonia and one in five needed help with breathing.
On average 60 days after their first symptoms of coronavirus, 87.4% always reported at least one symptom – in particular fatigue and shortness of breath – and 55% had three or more, report researchers in the Journal of the American Medical Association.
About one in four still had joint pain and about one in five had chest pain. About 44% said their quality of life was worse now than before their illness.
The researchers did not have information about the patients’ medical problems before COVID-19 and did not compare this relatively small group to the discharged patients for other reasons. But they said their results suggest that more research is needed on the lasting effects of coronavirus infection.
