The reason why cold weather is presumed to cause spreading of coughs, colds and flu is that cold air causes irritation in the nasal passages and airways, which makes us more susceptible to viral infection.

While cholera vaccines have been available for quite some time, most need to be injected, offer only limited and brief protection and can cause side effects, developing new, safe, longer-lasting vaccines which can be widely and easily administered is therefore vital ... (and) this vaccine could be a powerful weapon.

You saw the emotion crossing the line, I was stoked to keep the jersey in the team, to be able to take the jersey and keep it for Orica for another day.

It is virtually impossible to stop viruses crossing borders, so a weakness in any country is a problem for every country.

Unfortunately, the hospitality industry relies on people interacting and meeting and that is going to drive up infection rates.

When a virus is swilling around the population, it can mutate, every time it replicates( infects) there is the possibility of a mutation. While most of those are neutral or even damage the virus, every so often a mutation gives the virus a' fitness advantage,' which makes it more transmissible. Bluntly, the more people with a second dose, the less this thing can mutate in dangerous ways.

The idea that COVID-19 is caused by 5G mobile phone signals is complete rubbish.

If you enforce a quarantine utterly stringently, you can stop a virus escaping from an area, a really good way of slowing down transmission is to lock it in an area.

You can't stop people wanting to travel, and that has been the case for thousands of years, in exactly the same way that sailing goods around the world allowed bubonic plague into the UK, allowing people to fly around the world allows them to spread diseases.

Worryingly, it seems that the virus can pass from person to person without symptoms, making it extremely difficult to track, regardless of what health authorities do.

It's entirely possible that we might get a spring-time lull, it's unlikely to make things worse, but we don't know for sure - it's an educated guess.
