How do colds start

Do colds start by people who breathe in cold air, which may give them a runny nose, then baacteria breed?

Lots of reasons have been suggested. One is that the cold bugs can survive on surfaces for 12 hours or more and be passed on to the next person that touches them, and that in cooler weather they live longer.

I heard that cold weather will not give you a cold, but may lower your immunity, making you more susceptible to catching one.

Hadn’t heard of the runny nose theory, CN, but it sounds plausible.

PP, have you thought about joining a support group yourself?

As I understand it, the common cold is caused by coronavirus, which is mostly propagated orally. So if someone has the virus, they cough and sneeze over surfaces, and you may then ingest it, especially if you have poor hand to mouth hygiene. Transmission of the common cold is not usually by breathing in germs. Frequent hand washing is the key to prevention.

There is no direct correlation to being cold or wet. However, in winter people tend to congregate indoors, which promotes transmission. Also, if someone is cold and wet and miserable,the immune system is somewhat suppressed, again favouring virus transmission.

from going to TAFE which is a hotbed for sickness in the winter months

crowded situations where fluids are wiped on desks, door handles, clothing

if you see anyone wandering around like a super hero wearing a T-shirt, little clothing, have left coats open in the bitterest wind stay away from them – they are already infected!!

other signs will be a vacant stare, a stiff gait which shifts into a rapid shuffle, an insatiable taste for brains and the loss of recognisable speech.

the only purpose of eating garlic is to keep other people away from you and let them know you are infected – its the modern equivalent of wearing a bell around your neck and alerting airport staff that you are sick

Cold viruses evolved, they need a host to replicate far as I understand, which is some creature like you and me, but too I think they occupy cells and hijack them to replicate.

Wiki I reckon has a good page on common cold viruses.

the reason you’ll see infected people half clothed is because they’re body is heating up

one night in Sydney it must have bene very cold , yet strangely I felt hot when others were wrapped up. I felt great!

then you have that feeling something isn’t quite right and then hours later you are going into a full blown sickness

you’ll get sick when you are tired, sick or under stress. the more stress the more likely you’ll get sick and for longer – it wont matter what you try to take to ward it off
