That's what UC San Francisco medical student Joshua Lang wrote in his piece, With Summer Coming, Can the Zika Virus Be Contained?, published April 14 in The New Yorker.
Meanwhile, at UC Davis, plans are underway for a public "Zika Public Awareness Symposium," set Thursday, May 26 from 6:30 to 8:30 p.m. in Room 1001 of Giedt Hall.
"It is very important that students and the public-at-large learn how to prevent a possible Zika epidemic as this is the first virus known to be transmitted both sexually and by mosquitoes," said coordinator Walter Leal, a chemical ecologist and professor in the UC Davis Department of Molecular and Cellular Biology. Leal, who collaborates with fellow mosquito researchers in his native Brazil, is the co-chair of the International Congress of Entomology (ICE) meeting, to take place Sept. 25-30, 2016 in Orlando, Fla.
"This symposium is important to host because Zika is a rapidly spreading across the globe so people need to be informed," said Amarita Singh, one of the 18 students organizing the symposium. "Recent studies have shown that this particular virus not only affects pregnant women, but is a threat to all. Since there is no vaccine or medication, it is better to educate now to help prevention."
"I became more aware of the disease when Professor Leal began to discuss it in our biochemistry class, which is what originally sparked my interest," Singh said. "After learning about how dangerous the disease was and the discovery of the first case in Yolo County, I decided to take the opportunity in organizing the symposium."
Singh added: "It is incredible how much research has been done on Zika virus in the short amount of time. I am hopeful that in the near future that a vaccine will be developed, but until then we should do everything in our power to prevent this horrible virus from spreading. My concerns are that people may not be well informed which allows the virus to spread even more rapidly."
Said James Warwick, also one of the student organizers: "I think one of the scariest things about Zika in the United States is the lack of public knowledge about it. The scientific community needs to research the virus and develop a vaccine, but can't without funding. And without public pressure, securing funding is going to be slow. Also, the sheer suddenness in which Zika has burst onto the global scene has left both scientific research and public knowledge behind. That is why we are hosting the symposium, to bring the public up to speed, update them on the current research, and to give them the knowledge they need to protect themselves against transmission. As a byproduct, public awareness will increase public pressure to get the world on the right track to stop the spread of Zika."
"The virus itself is extremely alarming," Warwick said. "It can cause extreme neurological and immunological defects, as we see in babies born to infected mothers. But the direct hosts' symptoms usually consist only of temporary pain, rashes, fever, and the like; and only one in four or so people infected with Zika become symptomatic. So there is a very real possibility that a person could be infected, not be aware of it, and potentially pass on the undetected infection to sexual partners or their children. This is made all the more plausible by the fact that many people have never heard of Zika."
A flier (below) distributed at the campuswide UC Davis Picnic Day noted that the "Zika virus is a risk to all of us, not just to pregnant women." At the May 26th symposium, folks will "learn the symptoms and learn the facts and science about Zika and how you can protect yourself from this disease."
The scientific-based symposium will include "expert panels and speakers throughout the United States and the world, including those working on the front lines of the Zika epidemic." Speakers will be announced soon.
Attendance to the symposium is free, but due to limited space, those planning to attend are asked to RSVP to ucdstudentsagainstzikav@gmail.com

Countdown 'til UC Davis Picnic Day...
UC Davis will welcome thousands of visitors Saturday, April 16 to its 102nd annual Picnic Day, themed "Cultivating Our Authenticity." You can access the schedule of events here.
It promises to be educational, informative and entertaining.
In the UC Davis Department of Entomology and Nematology, graduate students are organizing numerous displays and activities in Briggs Hall on Kleiber Hall Drive. Director Lynn Kimsey, professor of entomology, and her crew are working on the displays in the Bohart Museum of Entomology, located in Room 1124 of the Academic Surge Building on Crocker Lane.
Three of the traditional exhibits coordinated by the department are nominees for special awards. They are:
- "Little Swimmers and Fly Tying” (Briggs Hall), nominated in the category, "Hidden Treasures"
- "Medical Entomology” (Briggs Hall), listed in the category, "Academic Exhibits" and
- "Real Insects and Mimics" (Bohart Museum of Entomology), "Family Friendly" Exhibit.
An online voting poll, available from 8 a.m. to 10 p.m. on Saturday, April 16, will determine the winners. Visitors may vote at https://orgsync.com/51524/forms/194037. Winning exhibits will be featured on social media pages such as the Picnic Day website, Facebook, Twitter, Instagram, and Snapchat accounts after Picnic Day. They also will be featured next year, in preparation for Picnic Day 2017.
The Briggs Hall open house will be from 9:30 to 4 p.m., and the Bohart Museum open house from 10 to 3 p.m.
Briggs Hall will be the site of a pollination pavilion, maggot art, cockroach races, fly-tying, face-painting, honey tasting, and a bee observation hive, and displays about ants, mosquitoes, aquatic insects and forest insects. The Bug Doctor booth ("The Doctor Is in") will be staffed by faculty and graduate students, while UC Davis forensic entomologist Robert Kimsey, aka "The Fly Man of Alcatraz," and entomology graduate Danielle Wishon will staff the Dr. Death table.
Honey tasting? Visitors can taste these varieties: Peppertree, eucalyptus, almond, sage, sweet clover, and pine "honey," according to Extension apiculturist Elina Niño of the Harry H. Laidlaw Jr. Honey Bee Research Facility.
Also at Briggs Hall, the UC Statewide Integrated Pest Management Program (UC IPM) will give away lady beetles, aka ladybugs, to kids to take home to their gardens. UC IPM also will provide advice on how to manage home and garden pests with environmentally sound methods.
The Entomology Graduate Student Association (EGSA) will be selling its popular insect-themed t-shirts.
At the Bohart Museum, the focus will be on "real insects as mimics." You'll see flies that look like bees--and bees that look like flies. In addition, you can hold and photograph the critters in the live "petting zoo," including Madagascar hissing cockroaches, walking sticks, and rose-haired tarantulas. The gift shop, featuring t-shirts, books, posters, insect collecting equipment, will be open.
Meanwhile, here's a look at some of "The Girls" you'll see: lady beetles (commonly known as ladybugs), Painted Lady butterflies, honey bees, all at Briggs Hall, and a rose-haired tarantula named "Peaches" at the Bohart Museum of Entomology.

They go together like honey bees on bee balm and bumble bees on tomatoes.
When you attend the 102nd annual campuswide UC Davis Picnic Day on Saturday, April 16, be sure to head over to Briggs Hall, Kleiber Hall Drive, to see the Pollinator Pavilion, which will emphasize the importance of pollinators in both natural environments and food production.
"It is often said that one in every three bites of food we take is dependent on animal pollination," said Pavilion Pollinator coordinator Margaret "Rei" Scampavia, a doctoral candidate in entomology. "While there are some foods that do not rely on animal pollination, many of the tastiest and most nutritious food does. To this end, we have a series of posters demonstrating what a meal might look like with and without foods that benefit from animal pollination."
"We are going to have a series of exhibits showcasing pollinator diversity, demonstrating their importance in natural ecosystems and food production, and providing information on what members of the general public can do to help native pollinators," Scampavia said.
"We will have information on a wide variety of animal pollinators, including butterflies, flies, wasps, birds, and even bats. But the majority of the exhibit will focus on the most abundant pollinators: native bees."
The highlight is the walk-in Pollinator Pavillion, an enclosure where visitors can "safely view live pollinators, such as bees, butterflies and flies, up close and in person," the entomologist said. "Younger guests can practice scientific observation by filling out specially provided data sheets. Some of the species present will include: blue orchard bees, Monarch butterflies, Red Admiral butterflies, and Painted Lady butterflies."
Scampavia points out that the European honey bee "is the first thing many people think of when they hear the word pollinator. But in reality, this species is only one of tens of thousands of pollinator species; there are more than 20,000 species of bee besides the honeybee, for example. We hope that visitors to this exhibit will leave with a greater appreciation of the amazingly diverse animals that pollinate flowers."
Last year scores of enthusiastic visitors packed the Pollinator Pavilion. It proved to be one of the most popular, well-crafted, well-designed Picnic Day displays. Another eagerly anticipated event awaits Saturday.
And now there's an urgency.
"Many pollinator species are experiencing alarming declines," Scampavia said. "Monarch butterflies, for example, have declined by over 90 percent in the past ten years. To promote awareness of the plight of the Monarch, we have a series of exhibits with live caterpillars, chrysalises, and adults, which also contain important information about this species and what we can do to prevent further losses. There will also be information about ways to enhance outdoor spaces to promote and sustain healthy wild, native pollinators."

If you've ever wanted to learn how to tell the difference between a honey bee and a drone fly, head over to the Bohart Museum of Entomology, University of California, Davis, during the 102nd annual campuswide UC Davis Picnic Day on Saturday, April 16. The overall theme of Picnic Day is "Cultivating Your Authenticity." The Bohart Museum's theme: "Real Insects and Their Mimics."
The Bohart, located in Room 1124 of the Academic Surge Building on Crocker Lane, is ready for your questions. They'll be open from 10 a.m. to 3 p.m.
The drone fly (Eristalis tenax) or European hover fly, is about the same size as a honey bee (Apis mellifera) and has similar coloring. They both visit flowers and sip nectar. But the drone fly has what appears to be an "H" on its back. The "H" does not stand for honey bee--but don't tell the fly that!
What is a drone fly? In its immature (larva) stage, it's known as a rat-tailed maggot. It lives in drainage ditches, manure piles and puddled, polluted water. The honey bee larva does not live in drainage ditches, manure piles, and puddled, polluted water.
But what a great mimic the adult drone fly is--so great that's it's commonly mistaken for a honey bee. One of the most memorable cases of misidentification occurred on the cover of Bees of the World, by Christopher O'Toole and Anthony Raw. Someone--not them--selected a fly for the cover. Major metropolitan newspapers, nature magazines, stock photo agencies and bee fundraisers have all made the same mistake. Here's a honey bee. Nope, that would "bee" a fly.
A quick way to tell the difference between a honey bee and a drone fly:
Wings:
Honey Bee: Four
Drone Fly: Two
Antennae:
Honey Bee: Elbowed antennae
Drone fly: Short, stubby antennae
Flight:
Honey Bee: Moves pointedly to a flower; it does not hover
Drone Fly: Hovers and moves erratically
Sting:
Honey Bee: Workers (and queens) can sting
Drone Fly: Does not sting. Does not bite.
Bottom line: Don't apply the "Duck Test" to honey bees and drones ("If it looks like a duck, swims like a duck, and quacks like a duck, then it probably is a duck").
"If it looks like a bee, buzzes like a bee, and visits flowers like a bee, well, you know, it may not be a bee; it may be a fly."

It shouldn't be, nor is it, at the University of California, Davis.
Medical entomologists and other scientists at UC Davis are planning a Malaria Awareness Day from 10 a.m. to 1:30 p.m. on Monday, April 25 in the Memorial Union.
The event will take place in MU II (second floor) and is free and open to the public.
Statistics from the Center for Disease Control and Prevention (CDC) tell the alarming story.
"It is a leading cause of death and disease in many developing countries, where young children and pregnant women are the groups most affected," the CDC points out, citing these figures from the World Health Organization's World Malaria Report 2013 and the Global Malaria Action Plan:
- 3.4 billion people (half the world's population) live in areas at risk of malaria transmission in 106 countries and territories
- In 2012, malaria caused an estimated 207 million clinical episodes, and 627,000 deaths. An estimated 91% of deaths in 2010 were in the African Region.
The most vulnerable groups, CDC says, are young children, who have not yet developed partial immunity to malaria; pregnant woman, whose immunity is decreased by pregnancy, especially during the first and second pregnancies; and travelers or migrants coming from areas with little or no malaria transmission, who lack immunity.
Africa, according to CDC, is the most affected due to a combination of factors:
- A very efficient mosquito (Anopheles gambiae complex) is responsible for high transmission.
- The predominant parasite species is Plasmodium falciparum, which is the species that is most likely to cause severe malaria and death.
- Local weather conditions often allow transmission to occur year round.
- Scarce resources and socio-economic instability have hindered efficient malaria control activities.
The schedule for the UC Davis Malaria Awareness Day:
10 to 10:30 am.: Coffee/social/posters
10:30 to 10:50: "General Malaria Biology" by medical entomologist Gregory Lanzaro, professor, Department of Pathology, Microbiology and Immunology, UC Davis School of Veterinary Medicine.
10:50 to 11:20: Conducting Field Research in Rural Africa" by medical entomologist Anthony Cornel, associate professor, UC Davis Department of Entomology and Nematology and based at the UC Kearney Agriculture and Research Center, Parlier
11:10 to 11:30: "Marlaria Parasites in the Mosquito" by molecular biologist Shirley Luckhart, professor, UC Davis Department of Medical Microbiology and Immunology and an adjunct professor in the Department of Entomology and Nematology
11:30 to 11:50: "Mosquito-Borne Viral Diseases" by medical entomologist Chris Barker, assistant adjunct professor and assistant research scientist, UC Davis Department of Pathology, Microbiology and Immunology
11:50 to 12:10: "Disease Transmission by Non-Mosquito Vectors" by epidemiologist/veterinarian and disease ecologist Janet Foley, professor, UC Davis Department of Medicine and Epidemiology
12:10 to 1:30: A free lunch will be provided, but reservations must be made by April 21 to ykyamasaki@ucdavis.edu.
