Viremia is a term that describes the presence of viruses in the blood. Viruses are microscopic organisms that survive and multiply within living hosts, such as animals and humans.
Minor cases of viremia can be relatively harmless and resolve on their own. However, if the infection becomes severe or causes infection in vital organs, it can lead to organ failure or sepsis, which is life-threatening, especially in those with compromised immune systems.
Viruses are parasites , which means that they depend on an external host for their survival and reproduction. Some viruses can get into the bloodstream, causing viremia.
The world of a virus
Viruses are tiny, 45,000 times smaller than the width of a human hair. They come in many shapes and sizes, but all known viruses share the same basic structure. They are made of genetic material, either DNA or RNA, wrapped in a protective protein shell called a capsid.
Many cases of viremia are mild or harmless, but if the infection becomes severe or affects vital organs, it can lead to organ failure or sepsis.
Causes
Most viruses can cause viremia, but although there are many types of viruses in the world, only a few cause disease in humans.
Some common or well-known causes of viremia include:
-HIV types 1 and 2
-influenza
-viral pneumonia
-viral meningitis
-varicella zoster virus
-measles, mumps and rubella
-rotavirus
-Enterovirus
-herpes
-human papillomavirus (HPV)
-hepatitis B and C
-Zika virus
-West Nile virus
-adenovirus
avian influenza virus
-Dengue
-yellow fever
-Japanese encephalitis virus
-cytomegalovirus
-ebola
-Rift Valley fever virus
-Rage
-polio
Throughout history, viruses have survived thanks to their incredible adaptability and resistance both inside and outside of a host.
Many viruses use bodily fluids to spread between hosts ; however, some viruses can live on a dry, non-porous surface, such as a plastic container, for 7 days or more.
Common ways of spreading viruses include:
-fecal-oral route (accidental ingestion of fecal matter)
-sexual contact
-contact with saliva or mucus (from coughing, sneezing or rubbing)
– mosquito or insect bites
-breast-feeding
-congenitally, from mother to fetus during pregnancy or delivery
-blood transfusion
-organ donation
-through cuts or serious injuries
General exhaustion, headache, and fever can be common signs of viremia and viral infection. Symptoms depend on the cause of the infection, but many viral infections cause a similar set of symptoms.
Common signs of viral infection and viremia include:
-fever
-general exhaustion
-muscle, joint weakness, pain and pain
-A headache
-dizziness or dizziness
-diarrhea, nausea or vomiting
-cold
runny or congested nose
-throat pain
-cough
-low appetite
Treatment
Recommended therapies for viral infections and viremia may include rest, fluids, and plenty of hot soup. For most viral infections, treatment involves dealing with the symptoms of the infection rather than the virus itself.
Typical therapies for viral infections and viremia include:
-break
-fluids, especially those high electrolytes
-Anti-inflammatory and pain relievers
-Antiemetic drugs
clear liquid foods, such as soup broth
-antihistamines
-Antidiarrheal drugs
anti-itch creams, such as hydrocortisone creams
-nasal decongestant medications and rinses
-throat pills or anesthetic sprays
-cough syrups
In severe cases, fluids can be given intravenously in a hospital.
