Summer is coming, but there is no need to fear the mosquito
1. In the first mechanism, a mosquito would initiate the cycle by feeding on an HIV-positive carrier and ingestingvirus particles with the blood. For the virus to be passed on, it would have to survive inside the mosquito,preferably increase in numbers, and then migrate to the mosquito’s salivary glands. The infected mosquito wouldthen seek its second blood meal from an uninfected host and transfer the HIV from its salivary glands during thebite. This is the mechanism used by most mosquito-borne parasites, including malaria, yellow fever, dengue, andthe encephalitis viruses.2. In the second mechanism, a mosquito would initiate the cycle by beginning to feed on an HIV carrier and beinterrupted after it had successfully drawn blood. Instead of resuming the partial blood meal on its original host, the mosquito would select an AIDS-free person to complete the meal. As it penetrated the skin of the new host,the mosquito would transfer virus particles that had adhered to the mouthparts from the previous meal. Thismechanism is not common in mosquito-borne infections, butequine infectious anemia is transmitted to horses bybiting files in this manner. 3. The third theoretical mechanism also involves a mosquito that is interrupted while feeding on an HIV carrier and resumes the partial blood meal on a different individual. In this scenario, however, the AIDS-free host squashes the mosquito as it attempts to feed and smears HIV-contaminated blood into the wound. In theory, any of the mosquito-borne viruses could be transmitted in this manner, providing the host circulated sufficient virus particles to initiate reinfection by contamination. Each of these mechanisms has been investigated with a variety of bloodsucking insects, and the results clearly show that mosquitoes cannot transmit AIDS. News reports on the findings, however, have been confusing, and media interpretation of the results has not been clear. The average person is still not convinced that mosquitoes are not involved in the transmission of a disease that appears in the blood, is passed from person-to-person, and can be contracted by persons that share hypodermic needles. Here are some reasons why the studies showed that mosquitoes cannot transmit AIDS: 18-033-0406

Why Mosquitoes Cannot Transmit Aids
MOSQUITOES DIGEST THE VIRUS THAT CAUSES AIDS
When a mosquito transmits a disease agent from one person to another, the infectious agent must remain alive inside the mosquito until transfer is completed. If the mosquito digests the parasite, the transmission cycle is ended and the parasite cannot be passed on to the next host. Successful mosquito-borne parasites have many interesting ways to avoid being treated as food. Some are refractory to the digestive enzymes inside the mosquito's stomach. Most bore their way out of the stomach as quickly as possible to avoid the powerful digestive enzymes that would quickly eliminate their existence. Malaria parasites survive inside mosquitoes for
9-12 days and go through a series of necessary life stages during that period. Encephalitis virus particles survive for 10-25 days inside a mosquito and replicate enormously during the incubation period. Studies with HIV clearly show that the virus responsible for the AIDS infection is regarded as food to the mosquito and is digested along with the blood meal. As a result, mosquitoes that ingest HIV-infected blood digest that blood within 1-2 days and destroy any virus particles that could potentially produce a new infection. Since the virus does not survive to reproduce and invade the salivary glands, the mechanism that most mosquito-borne parasites use to get from one host to the next is not possible with HIV. MOSQUITOES DO NOT INGEST ENOUGH HIV PARTICLES T0 TRANSMIT AIDS BY CONTAMINATION Insect-borne disease agents that have the ability to be transferred from one individual to the next via
contaminated mouthparts must circulate at very high levels in the bloodstream of their host. Transfer by mouthpart contamination requires sufficient infectious particles to initiate a new infection. The exact number of infectious particles varies from one disease to the next. HIV circulates at very low levels in the blood -- well below the levels of any of the known mosquito-borne diseases. Infected individuals rarely circulate more than 10 units of HIV, and 70 to 80 percent of infected persons have undetectable levels of virus particles in their blood.
Calculations with mosquitoes and HIV show that a mosquito that is interrupted while feeding on an HIV carrier circulating 1,000 units of HIV has a 1:10 million probability of injecting a single unit of HIV to an AIDS-free recipient. In laymen's terms, an AIDS-free individual would have to be bitten by 10 million mosquitoes that had begun feeding on an AIDS carrier to receive a single unit of HIV from contaminated mosquito mouthparts. Using the same calculations, crushing a fully engorged mosquito containing AIDS-positive blood would still not begin to approach the levels needed to initiate infection. In short, mechanical transmission of AIDS by HIVcontaminated mosquitoes appears to be well beyond the limits of probability. Therefore, none of the theoretical mechanisms cited earlier appear to be possible for mosquito transmission of HIV. MOSQUITOES ARE NOT FLYING HYPODERMIC NEEDLES
Many people think of mosquitoes as tiny, flying hypodermic syringes and if hypodermic needles can successfully transmit HIV from one individual to another, then mosquitoes ought to be able to do the same. We have already seen that HIV-Infected individuals do not circulate enough virus particles to result in infection by contamination. However, even if HIV-positive individuals did circulate high levels of virus, mosquitoes could not transmit the virus by the methods employed in used syringes. Most people have heard that mosquitoes regurgitate saliva
before they feed, but are unaware that the food canal and salivary canal are separate passageways in the mosquito. The mosquito's feeding apparatus is an extremely complicated structure that is totally unlike the crude single-bore syringe. Unlike a syringe, the mosquito delivers salivary fluid through one passage and draws blood up another. As a result, the food canal is not flushed out like a used needle, and blood flow is always unidirectional. The mechanics involved in mosquito feeding are totally unlike the mechanisms employed by the
drug user’s needles. In short, mosquitoes are not flying hypodermic needles, and a mosquito that disgorges saliva into your body is not flushing out the remnants of its last blood meal.

Coffee with Mom and Pop

I live in a False Creek South housing co-op less than 5 minutes from the Granville Market. But when I want to engage in that complex Vancouver ritual, "Coffee", I turn my back on GI and head a few blocks up the hill to the Wicked Cafe at 7th Avenue at Hemlock.
I graduated from Emily Carr last year, and since my own exchange in France in 2005, I've been sharing my place with successive art students from all over the world. I have been enjoying gazing at my city in a new way by peeking through their lenses. One of them found Wicked a couple of years ago, and since then all of us have come to use that as our "third place".
Though centrally located, Wicked is just enough off the beaten path that -- thankfully -- it hasn't drawn the attention of the tourists. But to someone drifting by, it is clear how their motto "putting the neighbourhood back in neighbourhood" has evolved. With warm weather, the patrons have ignored the sound of traffic and claimed the south-facing corner as an ad hoc plaza. When I was there last week, a second row of tables had sprouted between the sidewalk and the curb, and people were playing a board game.

Queen Elizabeth Park
Go faster, boy (while the Roseberry Bush looks up at the sky)
Flat noise bands in caterpillar beams of light rise against a freezing tide. The River tries with all of its might to keep moving. Laughter from a child resonates from across the water. She is about to capsize a seadoo. She is making a flag out of shells and green tempura paint.
It was a year ago on this day that her brother died in a seadoo accident. The motor was too fast. She never did like the colours from the fuel that leaked out of the sport and now she looks up at the sky every time she feels the wind pinch her skin.
Her brother saw animals in the sky. He told her about a dream he had one night. Dozens of tigers from a Northern Ontario town were chasing him with streamers in their fur. Red. He couldn’t fly in his dream, but he sure could run fast. A Santa Claus roseberry bush waited for him at the finish line.
With tigers in his own hair did he salute the oncoming snarls from the kittens that were fevered and full of ragweed. A touch of dust in his right nostril and then a sneeze that raised his feet off the ground. All of the tigers gestured the same gesture as they signaled to the boy to go faster. “We’ll get to the Roseberry bush before you will!” They teased his pride until the leaves that were falling from the trees hung on. He stared at them until they froze and he sped on. The leaves were sad to see a boy run so fast.
His teacher sent him home with extra homework that day. He just could not understand how the clock worked. He could not tell the time, and the rhyme that happened along the way only told him to think faster. “Think faster, Boy”. How does the twelve function in relation to itself after it has already been introduced as a day drifter? His teacher never mentioned the moon. And maybe the numbers have masks that they could place on their faces bi-daily, he thought. The numbers didn’t make sense.
His mother asked him to do the dishes, but he would rather beat the tide tonight. The seadoo waited at a dock that had been built forty-four years, twenty-seven days, thirteen hours, fifty-one minutes and six seconds before his birth. It aged with grace over the relentless seasons. The algae loved it so. The sailboats gathered enough strength to say: “The cedars look up at the sky too!” But the boy couldn’t hear them over the sound of the waves underneath the motor. The motor’s laughter was aggressive. All you could see was teeth when you closed your eyes.
One year later, his sister places rocks in her mouth. She leaves her mouth wide opened. Her flag is placed in a tree. It invites the leaves to shout, to fall, and to give themselves to the ground. The tigers in her dream are like painters who paint lines in rows of patterns, self-proclaimed lisps of avenues that follow daydream seasons. Time stops. Her legs, like pipes with chimes, follow the tune of the tide. It goes. Her eyes, looking up.

Chill Spot Map
Fort Makin'
"Walk to the centre of the Lion's Gate Bridge and watch the sun set"
To slow down is to die
I take this bus and smile wide
short change, million thoughts stream
out
suspended in the air around.
groggy flying things
after winter
this is what you said
walk to the centre of the Lion’s
watch the sun
set
document and publish
this is what I said
every ten minutes take two pictures. Pivot
on your right heel
the angle just
so
one charred sun setting
one bone moon rising
the balance and the wait.
when the lady-cop came,
I still felt the bridge sway with every passing car
she wanted to know if I was going to kill
myself,
but really, she was worried about
how long and slow and concentrated I was.
Cant be good for the mind to be so relaxed,
So resolved on watching the goddamned
sunset.
so deliberate and
stalling and
powerful
magic
hums louder than the whirr of passing traffic.
trembles the steel suspension wires and makes music
from city-dwelling pain
a deep heartbeat and sparkling blindness
be careful, you cant look it in the eye
we scurry around to
avoid the ends of us, and what we’ve made but
for her,
when we slow down
its like we've already jumped.
I also have photos to post once I've processed and printed them.

"Consider your relationship with the homeless people around you"
Since working in the mental health field my relationship to homeless people has definitely changed. I know now that if you are homeless and on welfare you don’t get any money for shelter… until you find somewhere to stay and then let The Ministry know about it. I also know that if you are on disability you only get about 500 bucks to live on a month. If you are considered employable it’s way, way less. I know a lot about the challenges homeless people face, and yet occasionally I find myself thinking, “Hmmm, no, not today… there are resources out there… drop-ins, food banks, shelters, The Ministry…”. Of course I forget that all of these things have their own stresses, stigma’s, burocracy, and drawbacks. Being involved in them takes up time and energy and they are all part of a system, which like many systems can perpetuate the very thing it seeks to change.
On April 4th I attended the March For Housing, an amazing and beautiful experience. People wore blankets over themselves to show that they were homeless – and to see them protesting and demanding action with a large mass of allies was very emotional. I recognised homeless people among the protestors and I was reminded of how often we forget to look not just at homeless people, but at each other and remember – this person has great depth – they are a brother or a sister, a lover, a teacher, a learner, an experiencer of suffering and of pleasure – I wonder what this person is like to live with, to laugh with, what their life story is…?
I think homeless people more than anyone else are overlooked for what we all are – human beings with great depth, a life story that we cannot possibly know based on the limited experience of a few encounters.
