Is pollen responsible for rise in Covid-19 cases?

As per scientists, as pollen levels increased in outdoor air in 31 countries, the cases of Covid-19 also increased. On the other hand, few others suggested that peaks in pollen seasons coincide with a fall-off in the spread of some respiratory viruses, like COVID-19 and influenza.

But now, a new study published in the Proceedings of the National Academy of Sciences said that when pollen in an area spiked, so did infections, after an average lag of about 4 days. The study authors say pollen seemed to account for, on average, 44% of the infection rate difference between countries.

It took data from 248 airborne-pollen-monitoring sites in 31 countries. The study also took into account other effects, such as population density, temperature, humidity, and lockdown orders.

In a press conference, study author Stefanie Gilles, PhD, chair of environmental medicine at the Technical University of Munich in Germany said, “When we inhale pollen, they end up on our nasal mucosa and here, they diminish the expression of genes that are important for the defense against airborne viruses.”

Hoogeveen’s recent study, published in Science of the Total Environment, found that the arrival of pollen season in the Netherlands coincides with the end of flu season, and that COVID-19 infection peaks tend to follow a similar pattern.

Another study said — as pollen climbs, flu cases drop. The researchers behind that study think pollen may actually compete with viruses in our airways, helping to block them from infecting our cells.

However, there is no strong scientific reason to support these different claims.

Study: 4th Covid vaccine dose effective in protecting people over 60

As per the new Israeli-led study, the largest healthcare organisation Clalit said fourth dose of Covid vaccine is effective for protecting people aged 60 and above.

The study found that a fourth dose can reduce the possibilities of symptomatic infection, hospitalisation, serious illness and mortality among the elders, Clalit said, Xinhua news agency reported.

In the study, published in the New England Journal of Medicine, Clalit researchers and their colleagues from Harvard University in Boston analysed data from 182,122 Clalit members, all aged 60 and above, who received Pfizer’s fourth dose.

“The study unequivocally demonstrates that the fourth dose provides effective protection in preventing morbidity,” said Ran Balicer, Director of the Clalit Research Institute.

“It will help every person to make a decision on the fourth vaccine based on their level of personal risk,” he added.

With the growing number of cases of long COVID it is confirmed that COVID does not spare any body organ and it affects the biological ecosystem. Fatigue, trouble in breathing and cognitive dysfunction is the most common symptoms.

Fatigue: It is very common response from the body when fighting against any viral infection. It may last for weeks and it is very common symptom seen in all the patients who recovered from COVID.

Trouble in breathing: Even with the minimal physical activity person may have trouble in breathing. It is very common occurrence in the people who have been infected with COVID.

Cognitive dysfunction: It is commonly referred as brain fog. It actually means people having trouble with their attention, trouble in concentrating, trouble in recall or memory, trouble in sleeping.
