Covid 19

In the acute phase, clinical manifestations and complications of Covid-19 of varying degrees have been documented, including death. However, patients who recover from the acute phase of the infection can still suffer long-term effects, commonly referred to as "long Covid". Now, the expanded CDC guidance suggests that documented serious post-Covid conditions include cardiovascular, pulmonary, neurological, renal, endocrine, haematological, and gastrointestinal complications as well as death.

Age was also a factor and older adults were less likely to be infected during the omicron wave (dominated by BA.1 and BA.2 sublineages) compared to younger adults, according to the study led by Dr Allison McGeer, Sinai Health System, University of Toronto, Canada, and colleagues. In addition, vaccination, as expected.

Researchers from the University of Colorado Boulder in the US found that airborne particles carrying a mammalian Coronavirus closely related to the virus, which causes Covid-19, remain infectious for twice as long in drier air, in part because the saliva emitted with them serves as a protective barrier around the virus, especially at low humidity levels.

The report, titled 'Trends in maternal mortality', showed that there were an estimated 287,000 maternal deaths worldwide in 2020.A Severe bleeding, high blood pressure, pregnancy-related infections, complications from unsafe abortion, and underlying conditions that can be aggravated by pregnancy (such as HIV/AIDS and malaria) are the leading causes of maternal deaths.

In heart tissue from patients who had Covid-19, the team from Columbia University observed increases in oxidative stress (harmful production of unstable molecules) and signals of inflammation, as well as changes in calcium. They also detected adverse changes to a protein called RyR2, which is responsible for regulating the heart's calcium ion levels.

In laboratory dish tests, extracts from the flowers of tall goldenrod (Solidago altissima) and the rhizomes of the eagle fern (Pteridium aquilinum) each blocked SARS-CoV-2 from entering human cells. The active compounds are only present in miniscule quantities in the plants. It would be ineffective, and potentially dangerous, for people to attempt to treat themselves with them.

People with underlying medical illnesses including diabetes, heart problems, hypertension, respiratory diseases, kidney troubles, etc. are even more at risk of contracting Covid, therefore the reissued Covid notice has caused them to express alarm.

According to a study published in the journal Nature, a team led by Tsang systematically analysed the immune responses of healthy people who had received the flu vaccine. From that data, they then compared the responses between those who had never been infected by SARS-CoV-2, the virus that causes Covid-19, and those who experienced mild cases but recovered.
