Types of Dengue

Dengue fever is a fever that can not be seen without the symptoms of dengue fever. Dengue fever can begin with a mild fever in the situation, but after that it will result in the deadly status of the victim. The symptoms usually last a week, but in some cases they begin to reappear two or three days. There are many types of dengue that affect life and can lead to conditions that threaten life. They are as follows: Dengue fever The symptoms of dengue are less common in small children, and in adults and in adult children these symptoms occur. They are as follows: The fever appears suddenly and is maintained for 3-7 days of the period. Strong headache especially in the back of the head. Pain in the muscles and joints of a victim, especially in the ankle and elbow. The taste of the mouth has changed. They can be exposed to vomiting, stomach pain and loss of appetite. Eruptions, itchy skin, legs etc. There is a small bleeding in the body part, such as nose, gum, etc., which is a

Zika virus

Highlights Zika's disease is caused by a virus that is primarily produced by Aedes mosquitoes. People with zika symptoms are symptoms such as mild fever, acne, conjunctivitis, muscle and joint pain, malaise or headache. These symptoms are usually 2 to 7 days. There is a scientific consensus that the Zika virus is a cause of micro-infection and Guillain-Barré syndrome. References to other neurological complications are also studied. introduction The Zika virus is a mosquito-transmitted taste trail that was identified in Uganda in 1947 by monkeys through a network that marked the yellow color. He was later identified by humankind in 1952 in Uganda and the United Republic of Tanzania. Interruptions of Zika virus are included in Africa, America, Asia and the Pacific. From 1960 to 1980, human infections were observed in Africa and Asia, usually accompanied by mild illness. The first major alteration of the disease caused by Zika infection occurred in the Federated States of Mi

VIRUS

1. Define virus. Ans: virus are unicellular ultramicroscopic particles contain either DNA &RNA that reproduce inside the living cell by replication is called virus. General character: 1. Do not process cellular organization. 2. contain one type of nucleic acid either DNA or RNA but never both. 3. Can not grow in culture media. 4. Multiply by replication in to the living cell. 5. Generally resistant to antimicrobial antibiotics. 6. Sensitive to interferon. Morphology of Virus: 1. Size: Viruses are very small in size.(20nm-300nm) 2. Shape: Viruses are are various types of shape – • Bullet • Brick • Sperm • Spherical Structure of virus: The hole virus particle is called virion. 1. Nucleic acid: A central core of nucleic acid(DNA or RNA) is called nucleic acid. 2. Capsid: A central core of nucleic acid surrounded by a protin coat is called capsid. 3. Capsomere: The capsid is composed of subunits is called capsomer. 4. Envlop:Viron may be enveloped or non coat of li

Human Papillomavirus

The human papilloma virus, or human papillomavirus, is more commonly referred to as HPV. The human papilloma virus is a name that represents a group of viruses that includes more than 100 different strains of the virus (see human papilloma virus pictures below). There are more than 100 different types of the human papillomavirus currently known. As commonly believed the human papilloma virus is not a new discovery. The papilloma virus dates back many centuries. Infections with this virus are known throughout the world. This virus is considered to be the most common sexually transmitted disease in the United States. Approximately 20 million people in the United States have the human papilloma virus infection.

The Structure of HIV

What does HIV look like? In this computer generated image, the large object is a human CD4+ white blood cell, and the spots on its surface and the spiky blue objects in the foreground represent HIV particles. Outside of a human cell, HIV exists as roughly spherical particles (sometimes called virions). The surface of each particle is studded with lots of little spikes. An HIV particle is around 100-150 billionths of a metre in diameter. That's about the same as: • 0.1 microns • 4 millionths of an inch • one twentieth of the length of an E. coli bacterium • one seventieth of the diameter of a human CD4+ white blood cell. Unlike most bacteria, HIV particles are much too small to be seen through an ordinary microscope. However they can be seen clearly with an electron microscope. HIV particles surround themselves with a coat of fatty material known as the viral envelope (or membrane). Projecting from this are around 72 little spikes, which are formed from the proteins gp120

First human 'infected with computer virus

Dr Gasson admits that the trial is a proof of principle A British scientist says he is the first man in the world to become infected with a computer virus. Dr Mark Gasson from the University of Reading had a chip inserted in his hand which was then infected with a virus. The device, which enables him to pass through security doors and activate his mobile phone, is a sophisticated version of ID chips used to tag pets. In trials, Dr Gasson showed that the chip was able to pass on the computer virus to external control systems. If other implanted chips had then connected to the system they too would have been corrupted, he said. Medical alert Dr Gasson admits that the test is a proof of principle but he thinks it has important implications for a future where medical devices such as pacemakers and cochlear implants become more sophisticated, and risk being contaminated by other human implants.
