Many species are infected by lentiviruses, which are characteristically responsible for long-duration illnesses with a long incubation period. Upon entry into the target cell, the viral RNA genome is converted reverse transcribed into double-stranded DNA by a virally encoded enzyme, reverse transcriptasethat is transported along with the viral genome in the virus particle. The resulting viral DNA is then imported into the cell nucleus and integrated into the cellular DNA by a virally encoded enzyme, integraseand host co-factors.

Scanning electron micrograph image depicting numerous clumps of methicillin-resistant Staphylococcus aureus bacteria; Magnified x. Infectious diseases can be caused by several different classes of pathogenic organisms commonly called germs.

Although microbes can be agents of infection, most microbes do not cause disease in humans. The majority of agents that cause disease in humans are viruses or bacteria, although the parasite that causes malaria is a notable example of a protozoan. Transmission of Infectious Diseases There are a number of different routes by which a person can become infected with an infectious agent.

For some agents, humans must come in direct contact with a source of infection, such as contaminated food, water, fecal material, body fluids or animal products. With other agents, infection can be transmitted through the air.

The route of transmission of infectious agents is clearly an important factor in how quickly an infectious agent can spread through a population. An agent that can spread through the air has greater potential for infecting a larger number of individuals than an agent that is spread through direct contact.

Another important factor in transmission is the survival time of the infectious Infectious diseases hiv aids in the environment. An agent that survives only a few seconds between hosts will not be able to infect as many people as an agent that can survive in the environment for hours, days, or even longer.

These factors are important considerations when evaluating the risks of potential bioterrorism agents. Impact of Infectious Diseases on Society credit: Infectious diseases have plagued humans throughout history, and in fact have even shaped history on some occasions.

The flu pandemic killed more than a half million people in the United States and up to 50 million people worldwide and is thought to have played a contributing role in ending World War I. This epidemic demonstrated that new infectious diseases are just a plane trip away, as air travelers rapidly spread the disease to Canada, the United States, and Europe.

Even though the SARS outbreak was relatively short-lived and geographically contained, fear inspired by the epidemic led to travel restrictions and the closing of schools, stores, factories, and airports. A prolonged and more widespread outbreak would obviously have had a much greater economic impact.

Infection occurs through direct contact with an infected animal camel or person, but if the virus were to adapt to humans over time, it could spread more easily from person to person. The disproportionate loss of the most economically-productive individuals has reduced workforces and economic growth rates of affected countries, especially those with high infection rates.

This impacts the health care, education, and political stability of these nations. In southern Africa where the infection rate is highest, life expectancy has plummeted in a mere decade from 62 years in to 48 years in — For the first time in the long history of flu pandemics, the beginnings of an outbreak were detected, and the spread of the disease was monitored on an almost daily basis as air travelers carried it around the globe.

The new H1N1 flu traveled around the world with unprecedented speed and in a few short months made its impact felt globally. Even though the disease was relatively mild for most people, some schools closed — more than across the United States at its peak - and a number of infected people were quarantined.

Mexico suffered great economic loss and damage to its tourism industry in an attempt to contain the outbreak in its early stage.AIDS Infonet. The AIDS InfoNet is a project of the International Association of Providers of AIDS Care (IAPAC) in the Infectious Diseases Division of the University of New Mexico School of Medicine.

The InfoNet was originally designed to make information on HIV/AIDS services and treatments easily accessible in both English and Spanish for residents of New Mexico. Infectious disease control involves not only prevention of transmission and spread of infectious disease at the population and individual levels, but also effective treatment and cure of infectious diseases .
