Any type of viral infection is caused by lytic viruses. These types of infections include pneumonia, influenza, and the common cold.
Some people may be allergic to flower pollen but it does not cause any diseases. Disease are generally caused by bacteria or viruses.
There are several different specific microbes that are identified to be the source of infectious diseases. The Rhinovirus causes colds. Varicella zoster causes chicken pox. Rubella causes German measles. Bordatella pertussis causes whooping cough. Yersinia pestis causes the Bubonic plague.
No Rhapsody itself does not have viruses. However it is possible that the ads that display on Rhapsody may cause viruses.
One is west nile virus, caused by mosquitoes.There are more than a dozen viruses that can cause encephalitis, spread by either human-to human contact or by animal bites. Encephalitis may occur with several common viral infections of childhood. Viruses and viral diseases that may cause encephalitis include:mumpsEpstein-Barr virus (EBV)cytomegalovirus infectionHIVherpes simplexherpes zosterherpes Bpoliomosquito-borne viruses (arboviruses)
Non-pathogenic diseases are conditions that do not result from an infectious agent (such as bacteria, viruses, or parasites) and do not cause harm to the host. These diseases may be genetic, autoimmune, or related to environmental factors, but they do not involve the invasion or colonization of the body by harmful microorganisms.
The lytic cycle causes destruction of infected cells and their membrane. A virus that uses a lytic cycle reproduces itself or makes copies that are sent back into the environment and they are called virulent viruses.
Simple viruses have a basic structure, with only a few genes and proteins, while complex viruses have a more intricate structure with multiple layers and components. Simple viruses typically cause mild infections and are easier to treat, while complex viruses can cause more severe diseases and may be harder to treat due to their sophisticated mechanisms of replication and evasion of the immune system.
Common diseases that cause blindness are onchocerciasis, syphilis, diabetes, glaucoma, trachoma. Many other less common diseases may cause blindness.
There are many infectious diseases that can affect animals, some of these may be passed on to humans (zoonotic diseases). Infectious disease may be caused by; bacteria, viruses, protozoa, parasites and many other classes of pathogens.
lack of nutrients in the diet may cause deficiency diseases
Viruses during the second trimester may be a cause of schizophrenia.
Virologists study viruses to understand how they spread, replicate, and cause diseases. They conduct research on different viruses, develop diagnostic tools, and work on developing vaccines and antiviral drugs. They may also track outbreaks, analyze data, and communicate findings to public health officials.
