How Does Malaria Infect The Body
Mosquito bites: A mosquito bites an infected person. The organism evolves in the mosquito. It then bites another person and the parasites get into their blood stream where they spread to the liver, evolve further and reproduce to be released into the blood intermittantly causing disease. This new person can now be bitten by another mosquito to continue the cycle. ...Read moreSee 1 more doctor answer
A life-threatening disease caused by parasites that are transmitted to people through the bites of infected female Anopheles mosquitoes. These parasites infect red blood cells, causing high fever, shaking chills, sweats, vomiting, muscle pain, headache, anemia. First symptoms occur 10 days to four weeks post infection, symptoms occur in cycles of ...Read more
Malaria Symptoms: may include headache, fever, shivering, sweating, fatigue, nausea, vomiting, dry cough, muscle/joint/back pain & enlarged spleen. There is a cyclic pattern of being very cold & shivering followed by feeling very hot and sweating. Additionally one can develop jaundice, blood in urine, anemia, eye problems (nystagmus, problems with eye movements), seizures & coma. ...Read more
Please see below: Children and adults who have giardia infection without symptoms usually don't need treatment unless they're likely to spread the parasites. Many people who do have problems often get better on their own in a few weeks. If you have to treat:metronidazole (flagyl). Tinidazole (tindamax). Nitazoxanide (alinia). ...Read more
Via the placenta: The only potential entry point for measles virus to a fetus is the shared blood supply with the mother (placenta/umbilical cord). Other potential invaders are kept out by the membranes that surround the fetus and the womb. For this reason, only a mother who becomes infected with measles during pregnancy can have a baby affected by the measles virus. If mom is immune, the fetus cannot get it. ...Read moreSee 1 more doctor answer
Body Defense : The body's defenses against infections: skin prevents organisms from entering from outside in, mucous protects sites ; washes away bacteria, antibodies attach to bacteria alerting immune cells to attack, cell mediated immunity (cells programmed to attack) seek ; destroy invaders, stomach acid kills microbes, gut bacteria block entry of invaders ; make microbicidal compounds; organic acids in urine. ...Read more
Ebola Virus: A person with Ebola infection may develop cough, chest pain, hemoptysis (coughing up blood), respiratory distress as well as Interstitial pneumonia and pulmonary edema with attempts to hydrate. Shock with capillary leakage, seizures, coma & respiratory distress herald death. ...Read more
Few hours when dry: Cdc has conducted many studies on HIV concentrations outside the body, when these are dried, the virus is reduced by 90to99% over several hours, these concentrations were much higher than they will be outside lab, making theoretical envorenmental transmission outside the body to zero. ...Read more
Viral infection: Viruses cannot live independently. They invade our cells and alter the metabolism of the cells such that the virus can replicate itself using the cell's resources and energy and often resulting in cell death, with release of virus particles that go on to infect other cells. ...Read more
Right antibiotic: Neisseria gonorrheae causes std gonorrhea; preferred drug is cephtriaxone unless pt is allergic to cephalosporins; alternate tx then would be spectinomycin. Neisseria meningitidis causes infection of the membranes covering the brain (meninges). Drug of choice is still penicillin g, unless allergic, in which case cephalosporin like cephotaxime or a fluoroquinolone like Ciprofloxacin will be used. ...Read more
Body fights malaria: Certainly our immune systems are very advanced -& will do everything to 'fight' against a serious infection like malaria. The immune system actually has many 'layers' to it and in an malarial infection many of those are activated. Fever is one-turning up the heat makes it harder for the parasites. Then there is the complement system, cellular immunity: B-cells & T-cells, plus immune organs -spleen ...Read more
Many ways: This is caused by a small bacteria which produces a small skin lesion at the site of the scratch in 1/2-3/4 of patients. Lymph nodes enlarge in the area closer to the body within about 10-14 days. At first these may be firm and tender, but then may break down and drain persistently. In some patients, particularly with impaired immune function it can affect the eye, liver, nervous system, etc. ...Read more
In many ways: Brucellosis presents initially as an illness with fever, muscle aches and sweats that can last for several weeks. The infection can localize to bone, kidney or central nervous system among others. The infection is generally acquired from livestock exposure or ingestion of unpasteurized dairy products. ...Read moreSee 1 more doctor answer
Herpes: Herpes virus isn't particularly bad to catch. Most people have exposure to herpes type 1 by the time they are 20. About 1 in 5 people show blood evidence of having been exposed to herpes type 2 virus. Most don't even know it. Some people do have trouble with frequent or severe outbreaks. Also it can rarely cause a serious infection of the brain. This is especially true for babies at time of birth. ...Read more
HIV dies right away: HIV cannot live outside of the body -which is a very good thing. So if you're worried about an 'exposure' at least this is in your favor. It's always good to practice safe sex though-esp. in this modern age. I see many young people not paying attention to their own safety-and sadly a number of new cases are occurring. Most of these are in gay young men in their 20s. Be safe. Check with a doc if Qs ...Read more
