New Invasive Mosquito Species Found in Pasadena

New Invasive Mosquito Species Found in Pasadena

Since 2016, there has been a single case associated with a Zika virus infected with a laboratory in the city of Pasadena, and no case of Zika acquired locally was reported to be PPHD.

As of June 30, 2017, there were 573 Zika related infections related to these trips through California, but there are no cases of locally acquired Zika in the state, according to the California Department of Public Health, www.cdph / Programs / CID / DCDC / CDPD% 20% 20Document Library / TravelAssociatedCases ofZikaVirusinCA.pdf. There has been no West Nile virus infection reported in Pasadena PPHD until 2017.

Invasive and non-native Aedes mosquitoes were present in Southern California since about 2001, including other parts of the San Gabriel Valley and include three different species.

Eggs found in Pasadena to date indicate the presence of only Aedes albopictus. The mosquito is about half the most common mosquito.

It bites mainly during daylight hours, not when other mosquitoes are generally active at dusk or dawn, and it stings a person repeatedly.

Those in charge of the health plan and the control of vectors to increase the vigilance and initiate the localized treatment where the breeding takes place. Clearly identified vector control agents also go door to door to help educate the public and take appropriate action. Currently, no extensive spraying is required.

Since the beginning of this year, PPHD has worked with SGVMVCD to annex the city to the district service area for mosquito and vector control services. The full merger is expected to begin in 2018.

Meanwhile, the City Council and the SGVMVCD in late June signed a memorandum of understanding that allows the SGVMCD to carry out surveillance, investigation, control and reduction of mosquito Aedes and public dissemination protection and prevention in Pasadena.

“Our best defense is education and prevention,” said Michael Johnson, director of PPHD. “Direct application of a treatment can occur when active breeding takes place, but people really need to be proactive to eliminate the least amount of stagnant water to avoid possible breeding.”

Aedes mosquito larvae can mature to become successful adult mosquitoes in containers with as little as a full bottle cap of water, so PPHD urges all who have increased vigilance in removing all sources of breeding environment for mosquitoes in Its properties, said Dr. Goh.

Additional measures to combat all types of mosquitoes include:

Drain it, rinse it with hot water, reverse it, cover it, or raise external objects that do not contain water, such as tires, buckets, pots, toys, swimming pools, bird pools or pyropières.

Keep pool water clean, disinfect and filter. Even with lagoons or bird bays.

Wear long-sleeved shirts and long pants outdoors if the weather permits.
Check door and window screens for holes, repair or replace.

When traveling, choose accommodation that has air conditioning and screens.
The Centers for Disease Control and Prevention recommends that pregnant women (or women planning to become pregnant) should avoid traveling to areas with Zika continuous transmission, including Latin America and the Caribbean, especially Mexico and Puerto Rico.

Zika virus was first identified in the 1950s as a tropical disease transmitted by mosquito bites. It has become a more pronounced health problem in South America, including negative birth defects, by 2015. People who get mosquito-borne viruses may not have obvious symptoms. It is possible that people with the Zika virus can infect others through sexual transmission or maternal transmission. Aedes mosquitoes can also become infected if they bite an infected person while they still have the virus in their blood.

For 125 years, PPHD worked to promote and protect the health of the Pasadena area. The department is accredited nationally by the Public Health Board of Accreditation.
