Viruses are exceptionally small infectious agents. They
comprise genetic material like RNA or DNA enclosed in a protein coating.
According to Wikipedia, a viral infection or viral disease takes place
when pathogenic viruses invade your body. Moreover, infectious virus particles, called
virions, get attached to susceptible cells and enter them. The cells in the
human body are invaded by viruses. They start using cell components to assist
them in multiplying. This process will end up damaging or destroying infected
cells. A viral infection is any health condition or illness triggered by a
virus. However, viruses are not necessarily contagious. Some common contagious
viral diseases are HIV, herpes, the common cold, and the flu. All viral
diseases are not necessarily contagious. However, many viral diseases are
contagious, like the common cold, herpes, and flu.
Respiratory Viral Diseases
Respiratory viral diseases commonly impact the lower or
upper parts of the respiratory tract and are contagious. Some symptoms of
respiratory viral infections are sneezing, coughing, a stuffy or runny nose,
body aches, and fever.
Flu is a common respiratory viral disease caused by the
influenza virus. Some common symptoms are a runny or stuffy nose, headache,
fever, body aches, and coughing. If you are pregnant or suffer from some
underlying disease, you may develop severe consequences and complications. It
is a good idea to get a flu vaccine every year to keep the viral infection at
bay. Visit the website MyBioSource.com to know more about
viruses and bacteria.
Common Cold: The common cold is a viral infection that
affects your sinuses, nose, windpipe, and throat. Colds may be transmitted
easily within workplaces, classrooms, and homes. Over 200 different viruses may
trigger common cold issues. The common cold has no cure, and generally, it goes
away in 7 to 10 days. You may consult your doctor or healthcare provider if the
symptoms persist even after ten days.
COVID-19: We know that COVID-19 is a deadly disease
triggered by the dangerous SARS-CoV-2 virus. We have witnessed how the COVID-19
global pandemic has adversely impacted and transformed our lives. COVID-19 may
result in severe respiratory issues, including death. You may get the vaccine
to protect yourself from the deadly coronavirus infection. Maintaining safe
social distance dictates washing hands frequently, wearing masks, and staying
away from infected or sick people are essential to keep COVID-19 at bay.
Gastrointestinal Viral Diseases
Viral infections can wreak havoc on your gastrointestinal
tract. Common examples are the rotavirus, norovirus, and astrovirus, each of
which causes symptoms similar to gastroenteritis. Liver disease can be caused
by hepatitis viruses too. Some of the common symptoms associated with
gastrointestinal viral diseases are diarrhea, abdominal cramps, and vomiting.
Exanthematous Viral Disease
Viruses have also been linked to several exanthematous
rashes and skin issues. These present as small bumps or inflamed blisters on or
just under the skin, but may have secondary symptoms and far-reaching
implications. Some examples include rubella (also called German measles),
chickenpox, mumps (or monkeypox), and roselle (the sixth disease).
Conclusion
Viral infections are an unfortunate reality in our
day-to-day lives. The vast majority of them are manageable and subside with
time. However, there are some viruses that, if unchecked, can take a serious
turn. Something as common as the flu can snowball into a very severe and
sometimes fatal condition. This is why it is very important to take protective
measures, ranging from good hygiene to safe sex and a proper vaccination
regimen.
