Transcript of Mosquito-borne Diseases

Malaria Dengue Mosquito-Borne Illnesses West Nile Triple E It is a virus
It is very rare among humans and only a few cases appear every year in the United States.
It is one of the deadliest mosquito transmitted diseases in the United States
Most people that acquire the disease don’t have an obvious illness. Importance and Implications Prevention for all these illnesses is the same: Vector Control. If the mosquito population is reduced (insecticides, mosquito breeding ground reduction) , the disease will have a much harder time getting transmitted. It is also important to keep in mind that mosquitoes breed better when the weather is warmer. Global warming is a growing issue, one that our country needs to acknowledge in order to combat.

Dengue kills 500,000 to 1 million people a year (Davis, Charles Patrick)
People in the US can get the disease: 2001 out break in Hawaii (Shepherd, Suzanne Moore)
Dengue cost countries a total of $587 million, without factoring in under-reporting of disease and dengue surveillance and vector control costs in 1995. This represents a significant global economic burden in low-income countries (Shepherd, Suzanne Moore)
West Nile infections have now been reported in 47 states, meaning you CAN get infected (The History of West Nile Virus)
Human cases and fatalities from West Nile virus have risen sharply since 1999, a phenomena which could be linked to increasing rainy springs and hot summers, ideal for mosquito breeding (global warming) (The History of West Nile Virus)
4,156 Americans infected by the West Nile in 2002, 280 died (The History of West Nile Virus)
Pyronaridine cured all 40 malaria patients in test in Cameroon, vs. chloroquine, most widely used drug, cured only 44 percent. If Pyronaridine had been available to all malaria sufferers over the last 25 years 50 million lives might have been saved. Cost is prohibitive: treatment with pyronaridine costs about $3, compared with 25 - 50 cents for chloroquine. To treat all the 300 million malaria patients with the more expensive drug would cost about $900 million a year. But, with mass production and further research, the drug's costs could be lowered. (Fischer, Dietrich) History The earliest known documentation of dengue fever–like illness is from China; records were found in the Chinese Encyclopedia of Symptoms during the Chin Dynasty, which was from 265-420 AD. The illness was called "the water poison" and was associated with flying insects near water.
Later major outbreaks happened in1779-80 in Africa, North America, and Asia

(Shepherd, Suzanne Moore) Statistics 50-100 million people are infected every year (Shepherd, Suzanne Moore)
According to a study, the average illness lasted 11.9 days for non-bedridden patients and 11 days for hospitalized patients. Hospitalized students lost 5.6 days of school, and those at work lost 9.9 work days (Shepherd, Suzanne Moore)
If untreated, dengue can have above a 50% mortality rate, but when patients are properly cared for, it can be less than 1% (Dengue) Signs and Symptoms Fever, up to 106 F (Dengue Fever)
Muscle, bone and joint pain (Dengue Fever)
Pain behind the eyes (Dengue Fever)
Headaches (Dengue Fever)
Weakness (Shepherd, Suzanne Moore)
Vomiting (Shepherd, Suzanne Moore) Prognosis Dengue Prognosis: For most, prognosis is excellent
most people recover in 1 to 2 weeks
Weakness can last up to a month
People with an immune system deficiency have an increased chance of complications Andrew Gendler

Derric Dellolio History Statistics Treatment Signs and Symptoms Treatment Prognosis History Signs and Symptoms Treatment (West Nile Virus) Prognosis (West Nile Virus) Systemic Infection
Symptoms chills
The symptoms last about 1-2 weeks Encephalitic Infection
Symptoms fever
coma Signs and Symptoms It takes about 4-10 days for the symptoms to set in after the bite
There are two possible illnesses systemic and encephalitic
Which one you develop depends on your age and other factors
Some people are lucky and don’t develop any symptoms at all Treatment There is no vaccine or specific antiviral treatment for clinical EEE Prognosis About 33% of all people who come down with the disease die

Death usually occurs 2-10 days after the onset of the symptoms

Survivors usually are left with a disability, mental or physical Dengue fever is mosquito borne virus that mainly infects the tropic and subtropic world (Dengue Fever). Because the symptoms are non-specific, the first step towards treatment is is a laboratory diagnosis (Shepherd, Suzanne Moore)
Unfortunately, no vaccine or treatment exists (Dengue)
Best thing to do is try to remain hydrated and wait out the symptoms. If the person is extremely ill, they should seek hospitalization (Dengue Fever) (Davis, Charles Patrick) http://www.umaa.org/images/mosquito.jpg (Eastern Equine Encephalitis) (Eastern Equine Encephalitis) (Eastern Equine Encephalitis) (Eastern Equine Encephalitis) (Eastern Equine Encephalitis) It is a virus
Malaria is an ancient disease probably originating in Africa.
Malaria produces recurrent attacks of chills and fever. Caused by a parasite that's transmitted by mosquitoes. Malaria kills about 1 million people each year worldwide.
Malaria has influenced to a great extent of the human populations and human history. In Africa over half a million (655, 000) people die from malaria each year, mostly children younger than five years old.
There are an estimated 216 million cases of malaria each year.
Approximately 3.3 billion people live in areas where malaria is a constant threat. Being with a few weeks after a bite from an infected mosquito it can start to affect you.
However, some types of malaria parasites can lie dormant in your body for months, or even years.
Symptoms and signs can be very similar.
Moderate to severe shaking, chills, high fever, profuse sweating as body temperature falls, headache, nausea, vomiting, and diarrhea. Moderate to severe shaking, chills, high fever, profuse sweating as body temperature falls, headache, nausea, vomiting, and diarrhea.
10% to 40% of people with severe malaria die even with advanced medical treatment. Treatment Depending on, your age, which type of malaria parasite you have, the severity of your symptoms, and weather you are pregnant.
The most common antimalarial drugs include:
Chloroquine (Aralen)
Quinine sulfate (Qualaquin)
Hydroxychloroquine (Plaquenil)
Mefloquine West Nile Disease is a mosquito transmitted virus, which symptoms range from mild to even not present, to deadly (West Nile Virus) West Nile was first isolated in Uganda in 1937
Serious outbreak in Israel in 1957
Reached New York City in 1999 (The History of West Nile Virus) fever
back pain Most symptoms will disappear without treatment
Over the counter medicine can be used to treat pain from muscle and head aches Most people recover in full
If meningitis or encephalitis (both inflammation of the brain) result from the West Nile, it is much more serious, as these are both life-threatening. If people get either of those, they face hospitalization, permanent neurological damage, or even death (West Nile Virus) (Malaria) (Malaria) (Malaria) (Malaria) (Malaria) (Malaria) (Eastern Equine Encephalitis)
