Infectious diseases can be caused by bacteria, virus, fungi and parasites through direct contact, indirect contact, insect bites and food contamination. Each infectious disease has its own specific signs and symptoms. General signs and symptoms common to many infectious diseases include fever, diarrhea, fatigue and muscle aches.

Infection Control in a health care facility is prevention of the spread of microorganisms from one individual to another individual to prevent these infectious diseases problems frequent hand washing, infection outbreak, water and food in hospital must be maintained.

Pediatric infectious diseases/ childhood infectious diseases are the infectious diseases which are caused in children of different age groups. Pediatric infectious diseases specialist’s takes care of the infections occurring in children and the treatment methods vary for children from adults.

Viruses are like hijackers. They invade normal living cells and use those cells to multiply and produce other viruses like themselves. This can kill, damage, or change the cells and make sick. Different viruses attack certain cells in your body such as your liver, respiratory system, or blood.

Bacteria are microscopic single-celled organisms that live almost everywhere. Bacteria live in every climate and location on earth. Some are airborne while others live in water or soil. Bacteria live on and inside plants, animals, and people. The word "bacteria" has a negative connotation, but bacteria perform many vital functions for organisms and in the environment.

Fungal Infectious Diseases are often caused by fungi that are common in the environment. Most fungi are not dangerous, but some types can be harmful to health. Mild fungal skin diseases can look like a rash and are very common. Fungal diseases in the lungs are often similar to other illnesses such as the flu or tuberculosis. Some fungal infections like fungal meningitis and bloodstream infections are less common than skin and lung infections but can be deadly.

Germs can cause infection in human blood and diseases are known as blood borne pathogens. The most common and dangerous germs spread through blood within the hospital are viral hepatitis B and hepatitis c virus. These viruses cause infections and liver injury. This virus cause AIDS. Organisms such as bacteria, viruses, prions, and parasites will be transmitted through blood transfusions. 

The infectious disease epidemiology encompasses domestic and global work on the epidemiology of emerging and re-emerging infections, global infectious disease threats, disease surveillance, disease detection, development of vaccines and other prevention methods, clinical trials, and the role of infectious pathogens in the pathogenesis of chronic non-communicable diseases such as cancer and cardiovascular disease. The broad range to search the novel pathogens using advanced molecular techniques to longitudinal population based studies to define transmission dynamics and spectrum of disease and survival. Approaches are employed in an interdisciplinary fashion to define etiology, pathogenesis, transmission, and prevention/treatment potential.

Global market report of infectious diseases is a complete study of current trends in the infectious diseases therapeutic and diagnostic market, industry growth drivers, advanced therapies and restraints. It provides market projections for the coming years. It includes analysis of recent developments in technology for infection diagnosis and treatment. Market reports also includes a review of micro and macro factors essential for the existing market players and new entrants along with detailed value chain analysis.

Tropical diseases encompass all diseases that occur solely in the tropics. In practice, the term is often taken to refer to infectious diseases that thrive in hot, humid conditions, such as malaria, leishmaniasis, schistosomiasis, onchocerciasis, lymphatic filariasis, Chagas disease, African trypanosomiasis, and dengue.

There are a number of infections and cancers that can develop in people who are living with HIV. There are infections that can be life threatening. These are also known as opportunistic infections. The more common life-threatening infections include a lung infection called Pneumocystis pneumonia (PCP), an eye infection caused by cytomegalovirus (CMV), a brain infection called toxoplasmosis, and a generalized infection called Mycobacterium avium complex (MAC). Cancers that are more common include Hodgkin’s lymphoma, lung cancer, skin cancer, anal cancer, cervical and vaginal cancer in women, and testicular and prostate cancer in men. These cancers can often be successfully treated if they occur in people with HIV who maintain healthy immune systems with HIV treatment.

An investigation of key characteristics of viruses, bacteria and other micro-organisms causing infections in humans. The mechanisms by which micro-organisms cause disease and evade the immune system are considered. It then explores the principle components of the immune system, describing the molecules and cells that protect against infection and cancer, and their contribution to innate and adaptive immune responses.

Pandemic, epidemic and endemic infectious diseases are united by a common problem to identify potential pharmacological interventions to treat infections. The large numbers of emerging and neglected infectious diseases are badly affecting the poorest members of the global society; new ways are required to develop high productivity discovery systems that can be applied to a large number of pathogens. The basis for developing methods to prioritize a priori potential drug targets analyzes the pharmacological landscape of an infectious disease.

These sciences are used to control human health through monitoring and control of zoonotic disease, infectious disease transmitted from non-human animals to humans, food safety, and indirectly through human applications from basic medical research food supply is through livestock health monitoring and treatment, and mental health by keeping pet’s healthy and long living. Veterinary scientists often collaborate with epidemiologists.

Antimicrobials/ antibiotics/ antibacterial are the drugs used in the treatment and prevention of bacterial infections. They may either kill or inhibit the growth of bacteria. Few antibiotics possess antiprotozoal activity. Antibiotics are not effective against viruses such as the common cold or influenza and their inappropriate use allows the emergence of resistant organisms.

Vaccines are the products that can produce immunity from a disease and can be administered through needle injections, by mouth and by aerosol. Vaccination is the injection of a killed or weakened organism that produces immunity in the body against that organism.

The infections experience in health care settings has become more challenging. Most of the duty workers get exposed commonly to a variety of infectious diseases during the performance of their duties. The primary route of infections transmission is airborne, contact (direct and indirect) which involves the entry of infectious agents from infected individual to a susceptible individual through physical contact and Indirect contact transmission occurs by susceptible individual physical contact with contaminated items. Infection conference 2018 is going to be a platform to discuss microbes that cause illness and its awareness of exposure in the health care settings.

Infectious diseases prevention and control is helpful to prevent the transmission of infectious diseases. Aseptic technique is normally applied to prevent the infections caused by different means. Sterilization is another process of killing microorganisms by the application of heat. Disinfection is the process of killing harmful microorganisms. Some infectious diseases can be prevented by avoiding direct contact with the contagious person. Infections can also be controlled and prevented by creating public awareness on various infectious diseases and their outbreaks. Infections can be cured by various antimicrobials.

Malaria is a mosquito borne infectious disease affecting humans and other animals caused by parasitic protozoans (a group of single celled microorganisms) belonging to the plasmodium type. Malaria symptoms typically include fever, fatigue, vomiting and headaches which can be observed in 10-15 after being bitten by mosquito. In severe cases, it can cause yellow skin, seizures, comaor and even death.

Most of the diseases have similar signs and symptoms but the samples of the infected host body fluid disclose the microbe cause the illness. However, the detection of microbes that causes infectious diseases plays key role in medical research.

A bone infection, also called osteomyelitis, can result when bacteria or fungi invade a bone.In children, bone infections most commonly occur in the long bones of the arms and legs. In adults, they usually appear in the hips, spine, and feet.Bone infections can happen suddenly or develop over a long period of time. If they’re not properly treated, bone infections can leave a bone permanently damaged.
