Herpes virus is a ubiquitous pathogen whose primary infections are usually
asymptomatic. There are two types of Herpes Simplex virus (HSV):
HSV-1 is known to cause orofacial disease such as cold sores; while
HSV-2 causes genital infections. Over 80% of the herpes infections
are asymptomatic; symptomatic infections are presented with
blistering sores, pain during urination, swollen lymph nodes, and
fever. Period of latency and mode of reactivation of HSV is yet
unclear.
Studies
have shown that over 80% herpes infections are asymptomatic, which
makes their timely diagnosis challenging. In cases where symptoms are
present, they appear in the form of blistering sores, fever, swelling
in the lymph nodes, and pain during urination. Because of this,
highly accurate and sensitive diagnostic tests are the only tool
available to physicians suspecting HSV infections. The global herpes
marker testing market currently features four types of HSV biomarker
tests – antigen tests, cell culture tests, polymerase chain
reaction (PCR), and antibody tests. The report on the herpes marker
testing market studies the uptake of each of these test types in
detail to emerge with details such as: the most widely-used test
currently, the future shares of herpes marker tests, innovations in
test techniques, and so on.
Hitherto,
PCR tests have led in terms of accuracy of results in diagnosing HSV.
The other benefit afforded by PCR tests is that they can help
diagnosticians identify HSV-1 and HSV-2 viral load. Cell culture
tests are also accurate, but carry the risk of misdiagnosis if the
skin lesion samples used for the test are in the process of healing.
Antibody and antigen tests, on the other hand, are based on enzyme
linked immunosorbent assays (ELISA). These tests, which use blood
samples for testing HSV antibodies and antigens, are quick as well as
accurate.

Statistics
from the Centers for Disease Control and Prevention (CDC) show a 16%
prevalence of HSV-2 among people in the U.S., with the
African-American female population being most widely affected. In
Canada, the country’s Public Health Agency has found the prevalence
of HSV-1 infection to be higher. Data also shows that about 70%
developed countries have HSV-1 seroprevalence among adults; in
underdeveloped countries, this rate is just short of 100%. However,
despite this, it is the North America and European regions that lead
the global herpes marker testing because of a higher percentage of
seroprevalence among the population in the countries in these regions
coupled with a high HIV patient population.

herpes marker testing market: DiaSorin, Enzo Life Sciences, Roche,
and Thermo Fisher Scientific.
