Health officials have noted for years that it affects an estimated 300,000 U.S. residents or more.Chagas disease, a cause of heart failure, stroke and sudden death, results from a parasite transmitted by “kissing bugs,” a committee stated in a medical journal Aug. 20.“Kissing bugs” get their nickname because they like to bite people on their faces.Doctors say the next time you’re out in a wooded area or on the patio, you should be on alert.But it isn’t the bite itself you should be concerned about, according to Dr. Robert Springer.“So while they’re biting you, ‘kissing’ you in the middle of the night, they also happen to be defecating there,” Springer said. “You wake up the next morning, you’re wiping the sleep out of your eye and you’ve just moved infected excrement into your eye and into your mouth mucous membrane. Then you become infected.”The excrement contains the parasite that causes the virus. The symptoms include swelling of the eye or area where the parasite entered the body. It can also be associated with fever and headaches, but in extreme cases, Chagas disease can be deadly.The disease can also be passed through contaminated food or drink, from pregnant mothers to their babies and through blood transfusions and organ transplants, the American Heart Association notes.The above map shows where “kissing bugs” have been reported across the U.S., according to the Centers for Disease Control and Prevention.“Worst-case scenario is a chronic infection that can involve the heart,” Springer said. “It can involve the intestines and especially in the heart. It can cause large enlargement of the heart and heart failure and other heart troubles, including rhythm disturbances.”“Kissing bugs” infest adobe houses in Central and Southern America, according to the American Heart Association. They are found across much of the U.S., but most indoor structures, built with plastered walls and sealed entryways, prevent insect invasion, and “kissing bugs” rarely infest indoor areas of houses.Not all “kissing bugs” are infected with the parasite that causes Chagas disease.The Centers for Disease Control and Prevention says the majority of the current cases are travel-related, meaning the person got the illness while traveling out of the country.Medications can cure infections caught early, the American Heart Association also notes.(Associated Press)last_img read more

first_imgIn a field traditionally dominated by men, the role of female engineers can often be downplayed. In recent years, however, the number of women in the industry is growing rapidly, and the Viterbi School of Engineering is helping to lead this effort.The Office of Women in  Engineering in Viterbi reports that 30 percent of its undergraduate population is female. Though that number might seem low in comparison to the 51 percent of women who make up the university’s student body as a whole, the American Society of Engineers reported that in 2011, only 18.4 percent of bachelor’s degrees in engineering went to women.Despite the fact that only 30 percent of women make up Viterbi’s undergraduate population, faculty and students said it often does not feel this way in their classes.Lianne Moreno, a freshman majoring in mechanical engineering, noted her classes were usually split equally between males and females.“In my classes, it is 50/50,” Moreno said. “In fact, in some of my engineering classes, I feel that there are even more girls than boys.”Milind Tambe, a professor in the computer science and industrial and systems engineering departments, made a similar remark. He has experience working with both students getting their Ph.D.s and students in Freshman Academy, a two-unit class that gives freshmen an introduction to engineering through guest lectures and team projects. Tambe said he has noticed that there is not a remarkable difference between male and female students.“In my classes, approximately half of the students are male and half are female,” Tambe said.Mia Smith, a senior majoring in environmental engineering, explained that students could be led to believe there are less women in certain classes because of the specific major’s demographics.“Some majors attract more women than others,” Smith said. “For example, when I take classes outside of my major, I sometimes feel there are more men since environmental engineering is more attractive to women. Still, I don’t feel outnumbered.”Students also felt that professors treat their students equally regardless of gender.“Professors are just as strict,” Moreno said. “They have the same expectations for boys and girls.”Many of the students agreed that Viterbi provides a supportive environment to its female students, and believe that this is one of the reasons why the male-to-female ratio of students in Viterbi is higher than the national average.“I believe that Viterbi is attracting more women into engineering because it has a diverse and engaging program that encourages women to take the lead in an engineering career,” said Leilani Rebolledo, a sophomore majoring in mechanical engineering.Viterbi offers a variety of programs catered to female engineers. One is the Society of Women Engineers, an organization with a main focus of creating a community of female engineers. The group hosts many networking events for its members.The Women in Engineering office also provides female students with opportunities for community outreach and a place where they can receive leadership development and professional support.Many of the students also said that aside from Viterbi having multiple programs, the feedback they received outside of the school has been rather positive.Moreno said when she would tell her family and friends that she was going to study engineering, they were encouraging.As for Smith, she agreed that she never received negative feedback and people were usually encouraging. Smith has engaged in a variety of international studies, and she said she has noticed that other countries are changing their perspectives in regard to women in engineering as well. During her semester studying abroad in Cape Town, South Africa, Smith noticed that in her engineering classes, there were far fewer women. She mentored high school girls who seemed very enthusiastic about studying engineering.“There is a lot of development going on in Cape Town, and many of the young women are eager to get involved in the engineering aspect,” Smith said.Smith also spent a summer in China working in a research lab and she was surprised by the number of female engineers.“I thought it would be the same, but there were many women engineers,” Smith said.Despite the changing industry, students are still aware of some of the prejudice that comes along with being female engineers.Alexia Gutiérrez, a junior majoring in environmental engineering, recalled the time when she was applying for an interview and they tried to discourage her.“They were surprised that I was a girl, and they started telling me that in construction sites it was very aggressive, suggesting that it would be a difficult environment for a woman to work in,” Gutiérrez said.Still, Viterbi’s female engineers viewed their role as somewhat of a challenge. Karishma Nagar, a senior majoring in industrial and systems engineering, has faced similar difficulties, but is glad to take on the challenge.“Eventually if you demonstrate a sound understanding of problems and come up with innovative ways to resolve them, you gain credibility and are taken just as seriously as your male counterparts,” Nagar said. “I don’t consider the prejudice as an obstacle. Rather, [it’s] a challenge to take on.”last_img read more
