Viral Fever Quotes

She's using you to get to me," Hi said confidently. "Both of them. They've caught Hiram fever." I nodded. "Of course. It all makes sense now.

How to spell Aedes aegypti,the world's one-stop, viral-disease-transmitting mosquito: T-R-O-U-B-L-E.

Incredibly, just one mosquito species, Aedes aegypti is responsible for the spread of four known different deadly viral diseases to human beings, yet this mosquito has been allowed to infest densely-populated urban centers.

The best herb for lowering seriously high fevers is coral root (Corallorhiza maculata), as either a tea or tincture.

The three friends stayed safe inside, but then they began to catch cabin fever. Being

DENGUE FEVER (BREAKBONE FEVER) Dengue fever is a viral infection found throughout Central America. In Costa Rica outbreaks involving thousands of people occur every year. Dengue is transmitted by aedes mosquitoes, which often bite during the daytime and are usually found close to human habitations, often indoors. They breed primarily in artificial water containers such as jars, barrels, cans, plastic containers and discarded tires. Dengue is especially common in densely populated, urban environments. Dengue usually causes flulike symptoms including fever, muscle aches, joint pains, headaches, nausea and vomiting, often followed by a rash. Most cases resolve uneventfully in a few days. Severe cases usually occur in children under the age of 15 who are experiencing their second dengue infection. There is no treatment for dengue fever except taking analgesics such as acetaminophen/paracetamol (Tylenol) and drinking plenty of fluids. Severe cases may require hospitalization for intravenous fluids and supportive care. There is no vaccine. The key to prevention is taking insect-protection measures. HEPATITIS A Hepatitis A is the second-most-common travel-related infection (after traveler’s diarrhea). It’s a viral infection of the liver that is usually acquired by ingestion of contaminated water, food or ice, though it may also be acquired by direct contact with infected persons. Symptoms may include fever, malaise, jaundice, nausea, vomiting and abdominal pain. Most cases resolve without complications, though hepatitis A occasionally causes severe liver damage. There is no treatment. The vaccine for hepatitis A is extremely safe and highly effective. You should get vaccinated before you go to Costa Rica. Because the safety of hepatitis A vaccine has not been established for pregnant women or children under the age of two, they should instead be given a gammaglobulin injection. LEISHMANIASIS Leishmaniasis occurs in the mountains and jungles of all Central American countries. The infection is transmitted by sand flies, which are about one-third the size of mosquitoes. Most cases occur in newly cleared forest or areas of secondary growth. The highest incidence is in Puerto Viejo de Talamanca. It causes slow-growing ulcers over exposed parts of the body There is no vaccine. RABIES Rabies is a viral infection of the brain and spinal cord that is almost always fatal. The rabies virus is carried in the saliva of infected animals and is typically transmitted through an animal bite, though contamination of any break in the skin with infected saliva may result in rabies. Rabies occurs in all Central American countries. However, in Costa Rica only two cases have been reported over the last 30 years. TYPHOID Typhoid fever is caused by ingestion of food or water contaminated by a species of salmonella known as Salmonella typhi . Fever occurs in virtually all cases. Other symptoms may include headache, malaise, muscle aches, dizziness, loss of appetite, nausea and abdominal pain. A pretrip vaccination for typoid is recommended, but not required. It’s usually given orally, and is also available as an injection. TRAVELER’S DIARRHEA Tap water is safe and of a high quality in Costa Rica, but when you’re far off the beaten path it’s best to avoid tap water unless it has been boiled, filtered or chemically disinfected (iodine tablets). To prevent diarrhea, be wary of dairy products that might contain unpasteurized milk; and be highly selective when eating food from street vendors.

The viruses that cause smallpox, influenza, hepatitis, measles, encephalitis, and viral pneumonia; the bacteria that cause tuberculosis, diphtheria, cholera, typhus, scarlet fever, and bacterial meningitis—by a quirk of evolutionary history, all were unknown in the Western Hemisphere.

Our work is not to get rid of viruses, or we would, by definition, fail. Our work is to live alongside viruses and to protect as many human lives as we can. This depends, in part, on what viral stories we tell, what viral metaphors we use. A virus killed my friend. I miss her every day. I live alongside viruses every day, missing her. Her memory will make me smile; her memory will make me cry. It will make me angry, forever, at influenza, the virus that took her away, but that anger won’t get her, or us, a second chance. As individual humans and the collective we together form, death or symbiosis are our only options. The planet cannot continue to sustain our abuse. Will we eat it alive, use up its resources, and leave it an unsuitable host for further human reproduction? What will this earn us? Continued wealth for a small number of human animals is all. Human reproduction is not driving global warming; wealth production is. Human wealth will be lytic, killing our host planet and us with it. Lysogeny may still be an option. Symbiosis. We could understand, like one of lambda’s stories, that treating the host well is treating us well. The earth’s well-being is our own well-being. Lambda has its choice made for it by molecules and circumstances and luck. We have our molecules and circumstances, but we can make more than luck. We must choose it, actively and every day, a lysogenic viral story, a living with and caring for the earth because it means caring for ourselves. A virus is not an enemy; if it is, we will only lose. Viruses aren’t the problem, they’re a fact of the world. We are the problem when we refuse to protect one another’s lives as the most precious things we have. You are precious to me. We might well prefer a world without viruses, their everyday annoyances, the fever or runny nose, the cold sores, the never-ending possibility of pandemic. We won’t get a day without them. I miss Sarah every day. Viruses aren’t going anywhere. We get to choose what we become. For my part, I live to be lysogenic. Won’t you join me here?

There is a widespread belief that Ebola and other viral hemorrhagic fevers cause profuse and irreversible bleeding in the humans they afflict. This is only rarely the case. So why has this belief taken hold?
