When a person tests positive for HIV, it is not a test for the virus itself but for antibodies to the virus, and the test is not able to distinguish between HIV antibodies and a multitude of other antibodies. Many conditions can lead to a false positive result, including flu shots, hepatitis, and pregnancy.
In the original introduction to the word meme in the last chapter of 'The Selfish Gene,' I did actually use the metaphor of a 'virus.' So when anybody talks about something going viral on the Internet, that is exactly what a meme is, and it looks as though the word has been appropriated for a subset of that.
Natural selection shaped the human brain to be drawn toward aspects of nature that enhance our survival and reproduction, like verdant landscapes and docile creatures. There is no payoff to getting the warm fuzzies in the presence of rats, snakes, mosquitoes, cockroaches, herpes simplex and the rabies virus.
Changes... can only be effected by alterations in the original. The only thing not prerecorded in a prerecorded universe are the prerecordings themselves. The copies can only repeat themselves word for word. A virus is a copy. You can pretty it up, cut it up, scramble it - it will reassemble in the same form.
The coronavirus has yet again exposed the strong contrast between President Trump - who is working ardently for the American people - and a Democratic Party with little interest in anything besides taking him down. President Trump, for his part, has taken unprecedented action to thwart the spread of the virus.
As a young physician in the mid-'80s, caring for people who had contracted H.I.V., I lost two of my patients to suicide at a time when the virus was doing very little harm to them. I have always thought of them as having been killed by a metaphor, by the burden of secrecy and shame associated with the disease.
An AIDS-free generation would mean that virtually no child is born with HIV; that, as those children grow up, their risk of becoming infected is far lower than it is today; and that those who become infected can access treatment to help prevent them from developing AIDS and from passing the virus on to others.
In San Francisco, I found Warren Levinson, who had set up a program to study Rous Sarcoma Virus, an archetype for what we now call retroviruses. At the time, the replication of retroviruses was one of the great puzzles of animal virology. Levinson, Levintow and I joined forces in the hope of solving that puzzle.
Then there is my country, the Philippines. President Rodrigo Duterte placed most of the country under a lockdown on the ides of March. Surrounded by men in uniform, he cut public transportation and talked about home quarantine, checkpoints and curfews, but said little about the virus or economic aid for those in need.
I had a dream, in 1985, I believe, when a friend I'd gone to school with was sick - one of the first people I knew who'd gotten the AIDS virus. I had a dream of him in his bedroom with an angel crashing through the ceiling. I wrote a poem called 'Angels in America.' I've never looked at the poem since the day I wrote it.
It's true that my research expertise is in biology: for example, the Ebola virus, the Marburg virus, and monkey pox, and not bacteriology as in the case of the anthrax organism. It's also true that I have never, ever worked with anthrax in my life. It's a separate field from the research I was performing at Fort Detrick.
McDermott and two colleagues - James H. Fowler of the University of California, San Diego, and Nicholas A. Christakis of Harvard University - published a paper titled 'Breaking Up is Hard to Do, Unless Everyone Else is Doing it Too.' Their study shows that divorce can spread like a virus among friends, siblings and co-workers.
Thinking ahead, in 2013, the Japanese government, together with pharmaceutical companies and the Bill & Melinda Gates Foundation, established a fund for promoting research and development of medical products for neglected tropical diseases (NTDs). The importance of planning for disease outbreaks was made clear with the Ebola virus.
This year, 1996, has been designated the 'Year of the Vaccine,' commemorating the 200th anniversary of Edward Jenner's vaccination of James Phipps with cowpox virus and subsequent challenge with smallpox virus. Insight into the nature of viruses, and how viruses interact with mammalian cells, has evolved since the turn of the century.
It's important to protect the old and the vulnerable, who are at the highest risk of severe illness and bad outcomes. But like most issues of medicine, it isn't a binary choice. Given the uncertainties of how this virus spreads and its high risk of infirmities, it would be unwise to abandon efforts to limit Covid spread wherever possible.
The fact that you have contracted Covid-19 isn't an easy thing to deal with. I was anxious and scared too, initially. Since I was alone, the first few days were all the more difficult. I was following instructions given by doctors but somewhere I was worried given how the virus has taken many lives and the kind of damage it has done to others.
It turns out that viruses evolve from each other, like everything else. So if you look at the evolutionary tree of viruses, you can find parts of their genome that haven't changed over evolutionary time. You can recognize what may be a new virus by identifying this little piece of their genome that hasn't changed and is represented on the chip.
I am the mom of two wonderful millennial young women who are bright and hardworking, and I will tell you what I told them: They are the core group that will stop this virus. They are the group that communicates successfully, independent of picking up a phone. They intuitively know how to contact each other without being in large social gatherings.
In the early days, a Georgia college kid named Chris Putnam created a virus that made your Facebook profile resemble MySpace, then the social-media incumbent. It went rampant and started deleting user data as well. Instead of siccing the F.B.I. dogs on Putnam, Facebook co-founder Dustin Moskovitz invited him for an interview and offered him a job.
