What is malaria and how serious can it be?

Malaria caused by mosquito bite that bring malaria parasite to your body. Every year, around 1750 traveller come to England bring malaria virus in their body. in several case, malaria can be deadly. unfortunately there are no vaccination for malaria yet. in exchange you can use a tablet  called prphylaxis to protect you from malaria for certain amount of time. this table ussualy work for certain area only. so you need to use the right tablet for area that you visit. most England travellers who catch malaria ussualy don’t use the right tablets for the right area, or do not take table at all.

malaria mostly found in tropical areas. They are  asia, large parts of africa,  haiti and the Dominican republic, Central and south america, some pacific ocean islands, and parts of the middle and far east.

Some people think that they have malaria immunity. they are people who come from area with malaria, and now live in UK. they also feel that their children have malaria imunity also. unfortunately this is not true. even if you have immunity to malaria, this immunity will soon vanish once you leave where malaria mosquito live. their children which born outside the area will not have immunity at all.

Malaria symptoms?

somtimes malaria symptoms misundestood as common flu. but it not often also that malaria turn into a deadly coma. here are some malaria symptoms:
body temprature increase more that 38°C
feel tired
feel cold while sweating
pain in the muscle
headache

Severe symptoms:
withing 24 hour after the first symptoms, the life threatening ussualy appear.

What to do if you are worried that you’ve got malaria

if you feel some sign of malaria, you should seek medical attention immediately. this should be done while you traveling and 1 year after your return. don’t panic with the sign. malaria can be identify by blood test and can be healed with drugs. for those who travel more than 24 hour away from medical site, are highly suggested to bring malaria self-treatment kits.

Twenty years ago Ebola virus first emerged in simultaneous outbreaks in Sudan (ref 1) and Zaire.(ref 2) Two subsequent outbreaks have occurred, (ref 3,4) but transmission among human populations has not been sustained. Despite substantial progress inside our idea of Ebola we haven’t identified its natural reservoir as well as trigger for its re-emergence in new outbreaks in humans. Despite all of this, the number of cases will inevitably rise within the next three weeks between already infected.

The viruses are classified in the family ‘Filoviridae’, with one genus, ‘Filovirus’. There are four known viruses. We now have Marburg virus and 3 Ebola viruses: Zaire, Sudan and Reston. Marburg and Ebola are distinguished by their length when purified. Within the unpurified state you obtain all different lengths of these worm-like virions. When they are purified, the infectivity occurs with a particular particle length, which happens to be slightly different between Marburg and Ebola, but all of the Ebola viruses are classified as the same length.

Human infection with African-derived strains has often occurred in caregivers, either family or medical, as well as folks who’ve got prepared dead relatives for burial. Late levels of Ebola are associated with the presence of huge numbers of virions in body fluids, tissues, and, especially, skin. Individuals who entered contact patients carrying Ebola without proper barrier protection are at danger of growing to be infected. A recent report out of your DRC identified Ebola virus RNA in 100% of oral secretions in patients with Ebola virus RNA in their serum.

The needle applied to Lokela¹s quinine injection was inadequately sterilized, so Ebola had spread from patient to patient because the needles were reused. They called Dr. Ngoi Mushola, the area director, for help. He taught them a way to sterilize their needles and purify water. He also told the nurses to teach patients¹ families do not bury their dead inside or on the point of their homes as tradition dictated, since Ebola could spread from dead bodies. He referred to as authorities in Kinshasa, the nation¹s capital, for help. Kinshasa sent a microbiologist or a epidemiologist who performed autopsies on dead patients and picked up samples.

Ebola virus is transmitted by contact with blood, feces or body fluids with infected person or by direct contact together with the virus, just as a laboratory. People will face Ebola virus from call together with the blood or secretions of any infected person. This is why herpes has often been spread throughout the families and friends of infected persons: in the midst of feeding, holding, or else looking after them, family members and friends would come into close communication with such secretions.

Herpes specifically affects liver cells and reticuloendothelial cells. Affected blood capillaries leak fluids and plasma proteins, causing intravascular coagulation and a zero clotting factor. The h2o volume absence of the system produces clinical shock, thereby causing the organs from the body to fail. The incubation period is usually from two to twenty-one days, and, according to the victim, symptoms occur fairly shortly after transmission. “All styles of viral hemorrhagic fever start off with fever and muscle aches. According to the particular virus, disease can progress till the patient becomes very ill with respiratory problems, severe bleeding, kidney problems, and shock. With Ebola, persons develop fever, chills, headaches, muscle aches, and lack of appetite.
