One thing about Covid-19 is clear: We don't fully understand its severity and transmission. At various turns, we've both underestimated and overestimated the virus.
Rumors of sneezing, kissing, tears, sweat, and saliva spreading AIDS caused people to panic.
Know that the tiger mosquito - Aedes albopictus - sometimes spreads viruses that spread like Zika, so it may be able to spread Zika.
I still cannot fathom how difficult it was for the women I met to find out that they were HIV-positive. It is such a courageous undertaking in countries where there is still considerable stigma about the disease. They got tested to ensure that their unborn babies would have a chance of life by being born free of the virus.
You can't take a knife on a plane anymore, but you can get on carrying a virus.
Ebola has arrived in New York City. And I say, 'if it can make it there...it can make it anywhere!'
Liability is being assessed against companies who inadvertently have shipped a virus to another company. Rather than risk the incredibly bad PR, these companies fork over.
The avian influenza found in mainland British Columbia poses no significant threat to human health.
All it takes is a single person coming into or going out of the jail or prison with COVID-19, and the entire jail will likely be infected. Most jails have people living in very close quarters.
Covid spreads too easily to think it can be confined to the young.
Of course, screening for HIV did essentially eliminate the transmission of this virus by transfusions.
Whereas HIV only in recent decades became infectious for humans, high risk papillomavirus types have in all likelihood been with us for millions of years, accompanying the human race since the early days of our evolution.
That the horrible Zika virus or HIV, we can look at what it means to be patient zero, what it means to need not much contact to spread, and all of those things follow into the way ideas spread.
Avoid activities outdoor. If you like to take an afternoon nap sleep under bed net. So these are measures that can be done to minimize [the] chance of infection [with Zika virus].
The difference between H7N9 and H5N1, is that H5N1 kills chickens very rapidly, so it is easy to identify where the infected flocks of chickens are. H7N9 doesn't make the chicken sick, so it has been difficult to pinpoint where the infected chickens are.
If a healthy person were placed on the other side of a room from a person who was sick with AIDS, the AIDS virus would not be able to drift across the room through the air and infect the healthy person.
The physical signs of measles are nearly the same as those of smallpox, but nausea and inflammation is more severe, though the pains in the back are less.
Without an adequate response, an epidemic can develop into a pandemic, which generally means it has spread to more than one continent.
The virus in the movie 'Contagion' is based on the bird flu which came out of nowhere back in 2008. Everyone thought it was going to change the way we live and it just faded away. Wait a minute, I'm talking about President Obama.
If we can contain and monitor animal viruses at an earlier stage - when they're first entering human populations, preferably before they've had a chance to become human-adapted, certainly before they've had a chance to spread - we can head off pandemics altogether.
When people asked him why he didn't work with those viruses, he replied, I don't particularly feel like dying.
I don't want to be in the clubhouse, if I have the coronavirus or something like that, coming into the clubhouse and spread to everybody, that's not good, right?
Some of the most vulnerable people to getting the SARS virus are health care providers. The general public, walking in the street, there is really not that much risk at all. It's a very, very low risk - a very, very low risk.
The fact is we can't prevent people from getting the COVID-19 virus.
Ebola isn't a respiratory virus. It doesn't spread through the airborne route. So it's not likely to spread like wildfire around the world and kill tens of thousands or hundreds of thousands of people. That's what I think of as the next big one.
