Yellow Fever

Yellow Fever is a viral disease transmitted by the bite of mosquitoes. A mosquito must first bit someone with the disease then come back and bite someone else.

The virus enters the body in the mosquitoes saliva.

Viruses work by entering a cell and taking over the function of the cell's nucleus, causing the cell to make multiple copies of themselves. These then burst out and go on to take over other cells. This process continues until the infected person dies OR until the persons immune system recognizes the virus and develops antibodies that surround and destroy the viruses so that they can no longer get to new cells.

The virus particularly targets liver cells and this causes liver damage which results in the jaundice (yellow color) of the affected person.

the filtering you may be referring to is filtering in search of bacterium which can be "caught in filters". however since yellow fever is a virus it is too small to be caught in the nets and thus can be passed on through blood to another person.

From Wikipedia:

"Most cases only cause a mild infection with fever, headache, chills, back pain, loss of appetite, nausea, and vomiting. In these cases the infection lasts only three to four days. In fifteen percent of cases, however, sufferers enter a second, toxic phase of the disease with recurring fever, this time accompanied by jaundice due to liver damage, as well as abdominal pain. Bleeding in the mouth, the eyes, and the gastrointestinal tract will cause vomitus containing blood. The toxic phase is fatal in approximately 20% of cases. In severe cases the mortality may exceed 50%."

yphoid fever and malaria are caused by parasites; typhoid fever comes about after contact with Salmonella typhi bacteria. The symptoms of both these diseases also do vary to a certain extent. Mostly, a malaria infection will manifest itself through chills, fevers, nausea, vomiting and sometimes even diarrhoea. However, the symptoms of typhoid are stomach pain, skin rashes, extreme muscle weakness and fatigue along with high fever.

A simple blood test (CBC) is enough to decide whether the person is suffering from malarial infection or not. However, in order to detect the presence of salmonella typhi widal test and typhidot are conducted.

Yellow fever is commonly found in tropical areas. The United States eradicated it by getting rid of mosquito breeding areas and putting screens on houses in the places it existed.

Yellow fever has that name because about 15% of the cases progress to a toxic phase including liver damage and jaundice. Jaundice causes the skin to turn yellow, hence the name.

Benjamin Rush was a great and selfless man who actually treated patients with yellow fever in 1793. He was a physician who lived in Philadelphia. When the there was a yellow fever epidemic in Philadelphia he worked tirelessly to care for patients and to prevent spread of the disease. He also kept detailed records of what he found out from the patients, hoping that his research might help find a cure.

There is no single pill to cure typhoid and yellow fever. You have a pill to cure typhoid but no pill to cure the yellow fever. Yellow fever is a viral infection and there is no specific pill for the same.

Dr. Fred Soper spearheaded the effort to eradicate Malaria in Panama.

Yellow fever causes dizziness, high temperature, body ache, and rashes

There is not enough study on this topic for complete analysis yet, however, the data from the pandemic of 2009 is being studied to get a better understanding of this aspect of infectious viral diseases. But, more is being discovered that suggests perhaps women are more affected by the flu than men.

The current thinking is that more women can be exposed to the viruses that cause influenza, as they are commonly in the role of caregiver to the ill and more likely to catch the viral disease.

Because there is a link between asthma and chronic lung disease and a more severe reaction to infection by influenza viruses, women again are more affected than men, since the severity of asthma and chronic lung diseases is often worse in women than in men.

The outcome and complications are also thought to be worse in women, especially pregnant women and some factor of the hormones may be in play.

An yellow fever virus causes yellow fever.

With a population of approximately 55,000 in 1793, Philadelphia was America's largest city, its capital and its busiest port. The summer of that year was unusually dry and hot. The water levels of streams and wells were dangerously reduced, providing an excellent breeding ground for insects. By July the city's inhabitants were remarking on the extraordinary number of flies and mosquitoes that swarmed around the dock area. That same month, a trickle of refugees escaping political turmoil in the Caribbean Islands became a torrent of thousands as ship after ship unloaded its human cargo on Dr. Benjamin Rush,

Philadelphia's leading physician.

His tireless efforts to save the

plague's victims were unsuccessful. Philadelphia's docks. Unbeknownst to the city's inhabitants, all the necessary ingredients for an unprecedented health disaster were now in place. With them, the Caribbean refuges brought Yellow Fever. Philadelphia's ravenous mosquitoes provided the perfect vehicle for spreading the disease by first lunching on an infected victim and then biting a healthy one. The first fatalities appeared in July and the numbers grew steadily. Victims initially experienced pains in the head, back and limbs accompanied by a high fever. These symptoms would often disappear, leaving a false sense of security. Shortly, the disease would announce its return with an even more severe fever and turn the victim's skin a ghastly yellow while he vomited black clots of blood. Death soon followed as the victim slipped into a helpless stupor. Unaware of the link between the mosquito and the disease's progress, Philadelphia's medical community was dumbfounded. Dr. Benjamin Rush, the city's leading physician and a signer of the Declaration of Independence, advised citizens to flee the city. He worked tirelessly to comfort and save the afflicted, but with little success. A good portion of the population, along with members of Congress, President Washington and his Cabinet, abandoned the city. The disease subsided and finally disappeared with the arrival of cold weather in November. It is estimated that 2,000 died. ADVERTISMENT "The horrors were heart rendering." Samuel Breck was a Philadelphia merchant newly arrived to the city: "I had scarcely become settled in Philadelphia when in July, 1793, the yellow fever broke out, and, spreading rapidly in August, obliged all the citizens who could remove to seek safety in the country. My father took his family to Bristol on the Delaware, and in the last of August I followed him... I was compelled to return to the city on the 8th of September, and spend the 9th there.Everything looked gloomy, and forty-five deaths were reported for the 9th. And yet it was nothing then to what it became three or four weeks later, when from the first to the twelfth of October one thousand 'persons died. On the twelfth a smart frost came and checked its ravages. The horrors of this memorable affliction were extensive and heart rending. Nor were they softened by professional skill. The disorder was in a great measure a stranger to our climate, and was awkwardly treated. Its rapid march, being from ten victims a day in August to one hundred a day in October, terrified the physicians, and led them into contradictory modes of treatment. They, as well as the guardians of the city, were taken by surprise. No hospitals or hospital stores were in readiness to alleviate the sufferings of the poor. For a long time nothing could be done other than to furnish coffins for the dead and men to bury them. At length a large house in the neighborhood was appropriately fitted up for the reception of patients, and a few pre-eminent philanthropists volunteered to superintend it. At the head of them was Stephen Girard, who has since become the richest man in America. In private families the parents, the children, the domestics lingered and died, frequently without assistance. The wealthy soon fled; the fearless or indifferent remained from choice, the poor from necessity. The inhabitants were reduced thus to one-half their number, yet the malignant action of the disease increased, so that those who were in health one day were buried the next. The burning fever occasioned paroxysms of rage which drove the patient naked from his bed to the street, and in some instances to the river, where he was drowned. Insanity was often the last stage of its horrors." "The attendants on the dead stood on the pavement soliciting jobs" Breck recounts the experience of his father's neighbor: "...Counting upon the comparative security of his remote residence from the heart of the town, (he) ventured to brave the disorder, and fortunately escaped its attack. He told me that in the height of the sickness, when death was sweeping away its hundreds a week, a man applied to him for leave to sleep one night on the stable floor. The gentleman, like everyone else, inspired with fear and caution, hesitated. The stranger pressed his request, assuring him that he had avoided the infected parts of the city, that his health was very good, and promised to go away at sunrise the next day. Under these circumstances he admitted him into his stable for that night. At peep of day the gentleman went to see if the man was gone. On The Philadelphia Docks opening the door he found him lying on the floor delirious and in a burning fever. Fearful of alarming his family, he kept it a secret from them, and went to the committee of health to ask to have the man removed. That committee was in session day and night at the City Hall in Chestnut Street. The spectacle around was new, for he had not ventured for some weeks so low down in town. The attendants on the dead stood on the pavement in considerable numbers soliciting jobs, and until employed they were occupied in feeding their horses out of the coffins which they had provided in anticipation of the daily wants. These speculators were useful, and, albeit with little show of feeling, contributed greatly to lessen, by competition, the charges of interment. The gentleman passed on through these callous spectators until he reached the room in which the committee was assembled, and from whom he obtained the services of a quack doctor, none other being in attendance. They went together to the stable, where the doctor examined the man, and then told the gentleman that at ten o'clock he would send the cart with a suitable coffin, into which he requested to have the dying stranger placed. The poor man was then alive and begging for a drink of water. His fit of delirium had subsided, his reason had returned, yet the experience of the soi-disant doctor enabled him to foretell that his death would take place in a few hours; it did so, and in time for his corpse to be conveyed away by the cart at the hour appointed. This sudden exit was of common occurrence. The whole number of deaths in 1793 by yellow fever was more than four thousand."

Paracetamol and vitamin B-complex tablets are being administered in large quantities and patients are being advised to consume lots of fluids and take rest. It takes weeks and sometimes months for patients to be completely rid of the disease.

Prevention involves good hygiene and decent living conditions. When this is impossible, insecticide dusting powders are available to apply to clothing.

Yellow Fever begins with a severe headache, sensitivity to light and a sense of apprehension (that something bad is going to happen). Then the fever begins and terrible body aches set in along with extreme dizziness. The victim then begins to vomit black blood uncontrollably. The tongue swells and the face flushes as the fever continues to rise. Some victims will begin to gradually recover at this stage. Others will see a continued high fever with delirium and heart palpitations. For some, the fever will suddenly drop and the person will feel very normal, as if they have recovered, but this almost always means the victim is going to die. During this 'normal' phase, any sudden exertion will almost always cause a heart attack in the victim and any food eaten will cause organ failure. After a short while during which the patient feels perfectly healthy, the fever will suddenly return with violent convulsions. The organs in the body shut down and just before the victim dies, jaundice turns the skin and eyes a deep golden-yellow, thus the name 'yellow fever'.
