These pathogens are typically transmitted person-to-person via the respiratory route. he rapid spread of Covid-19 forced many countries to lockdown and create national containment policies leading to a significant reduction in people's movements in all countries.

45% of Covid patients left hospital in worse physical state: Study
Of survivors who experienced a functional decline, 80 per cent were referred for additional therapy after being discharged. Nearly 20 per cent of all patients lost so much ability that they were not able to live independently after their release, indicates the study. "Rehabilitation needs were common for these patients," said lead author Alecia K. Daunter from the University of Michigan.
Mild Covid-19 induces antibody protection lasting lifetime
Researchers at Washington University in St. Louis, US, found that during a viral infection, antibody-producing immune cells rapidly multiply and circulate in the blood, driving antibody levels sky-high.
Once the infection is resolved, most such cells die off, and blood antibody levels drop. However, a small population of antibody-producing cells, called long-lived plasma cells
Sniffer dogs show 88% accuracy in detecting Covid: UK study
The study, involving scientists from the London School of Hygiene and Tropical Medicine and Durham University, believe the dog screening, followed by swab testing, will pick up 91 per cent of infections, the BBC reported on Monday. While even the quickest Covid tests take 15 minutes to show a result, the dogs can sniff out the disease in seconds.
Organic salts detected on Mars: NASA
A study, published in the Journal of Geophysical Research: Planets, found that organic salts, such as iron, calcium, and magnesium oxalates and acetates, may be widespread in Martian surface sediments. These salts are the chemical remnants of organic compounds. Organic compounds and salts on Mars could have formed by geologic processes or be remnants of ancient microbial life, NASA said in a statement.
Could Covid-19 cause erectile dysfunction in men?
Stress directly affects our hormones and mood and can take away a person's libido, thereby affecting quality time of a couple. It can also cause one to indulge in smoking or alcohol consumption which in turn can adversely affect sexual performance. These can lead to problems such as premature ejaculation, erectile dysfunction, reduced libido, and male fertility.
NASA rover to search for water, other resources on Moon in 2023
As part of the Artemis programme, data from the Volatiles Investigating Polar Exploration Rover (VIPER) would help the scientists map resources at the lunar South Pole that could one day be harvested for long-term human exploration at the Moon, the agency said in a statement late on Friday. "The data received from VIPER has the potential to aid our scientists in determining precise locations and concentrations of ice on the Moon and will help us evaluate the environment and potential resources at the lunar south pole in preparation for Artemis astronauts," said Lori Glaze, director for NASA's Planetary Science Division at the agency's headquarters in Washington, DC.
People bid over $2mn for first ride on Blue Origin's spaceship
