The Naples phlebovirus spreads via phlebotomine sand flies. Its epidemiology was studied in the Mediterranean Basin.
A PLOS Neglected Tropical Diseases study shows infections from Phlebovirus genus, like Naples phlebovirus, are emerging in the Mediterranean and may spread more in coming decades. The actual incidence is unknown, but over 250 million people are exposed to these pathogens.
An MDPI article evaluates human exposure to sandfly-borne phleboviruses in Turkey, an endemic region. It detected neutralizing antibodies to three phleboviruses: Toscana, sandfly fever Naples (SFNV), and sandfly fever Sicilian (SFSV) viruses. Toscana exposure was most frequent at 22.6% prevalence, followed by SFNV (15.3%) and SFSV (12.1%).
While the exact burden from Naples phlebovirus remains unclear, these studies indicate its presence and potential spread in the region.
The Naples phlebovirus is from the genus Phlebovirus in the family Phenuiviridae. It has an envelope, which is a lipid layer taken from a host cell’s membrane. This envelope surrounds the virus’s genetic material and proteins.
The Naples phlebovirus genome is divided into three separate RNA strands, called large (L), medium (M), and small (S). Every strand carries instructions for different viral proteins.
These viral parts are crucial for infecting cells, copying itself, and spreading to new hosts. The glycoproteins Gn and Gc help the virus attaches to and enter host cells. The RdRp enzyme copies the viral genome inside infected cells. The nucleocapsid protein encases and protects the viral RNA.
Naples phlebovirus can make humans sick. There are two main groups: Naples and Sicilian. These groups cause sandfly fever. Sandfly fever makes you have muscle pain, fever, and high liver enzymes. Naples phlebovirus is sorted into the Sandfly Fever Naples Virus (SFNV) group. This group has types that often infect humans.
The Naples phlebovirus brings about a sequence of happenings within the human body. The virus gets in, ordinarily through an infected sandfly’s bite. It targets cells that enable its replication. The virus’s exterior glycoproteins aid its entry into human cells.
Inside the cell, viral replication commences utilizing an RNA-dependent RNA polymerase coded by its tripartite RNA genome’s L segment. This process yields new viral proteins and assembled virions within infected cells.
The body’s innate immune reaction kicks in upon viral presence, producing interferons and cytokines to curb viral spread. Yet, Naples phlebovirus, akin to other Phlebovirus genus members, has evasion tactics like the non-structural NSs protein suppressing interferon signaling.
As infection advances, systemic sandfly fever symptoms may manifest fever, muscle pain, and elevated liver enzymes. Severe neurological effects sometimes occur, though less frequently with Naples phlebovirus versus related viruses like Toscana.
The human body has defenses against Naples phlebovirus, which causes sandfly fever in people. These defenses involve the innate and adaptive immune systems. First, the innate immune system reacts. It has barriers like skin and mucous membranes. It also has immune cells like macrophages and dendritic cells.
These cells sense the virus through special receptors. They can then release interferons (IFNs) and other cytokines. These substances block the virus from replicating and activate more immune cells. Next is the adaptive immune response. This response is more specific. B cells make antibodies that neutralize the virus. They stop it from infecting cells. T cells are another part of this response. They destroy infected cells and help control the infection.
Studies show that certain proteins restrict the Naples phlebovirus. These are called interferon-induced transmembrane proteins (IFITMs). IFITMs block the virus from fusing with host cells and prevent the virus from entering cells. However, phleboviruses have a protein called NSs. NSs can suppress the body’s interferon response. This interferon response is key for innate immunity against viruses.
Understanding how the virus interacts with immunity is vital. Learning this can lead to new therapies and vaccines.
Naples phlebovirus infects people. Symptoms include fever, not feeling well, lack of appetite, eyes hurt in bright light, stomach problems, and rash. Many people have no symptoms. Others get symptoms quickly. Muscle pain, high body temperature, and higher liver enzymes also occur. These show Naples phlebovirus infection in people.
A virus called Naples phlebovirus can pose challenges for diagnosis. The virus shows diversity and complexity. Its infections often present nonspecific symptoms. Still, there are ways to detect this virus from human samples:
Blood tests that examine antibodies. These look for proteins the immune system produced to fight the virus. Finding certain antibodies indicates an ongoing or previous infection.
Advanced molecular testing, known as quantitative PCR (qPCR). This method pinpoints the virus’s genetic material with high sensitivity. Even low virus levels can reveal positive results.
To avoid Naples phlebovirus, there are several essential steps:
Protect Yourself: Use bug spray on skin and clothes, and wear long sleeves and pants when sandflies are most active so they can’t bite you.
Clean Up Outside Get rid of places where sandflies breed by cutting plants and bushes around your home, and spray insecticide if needed. Also, put screens on windows and doors to keep sandflies out of your house.
Spread the Word: Teach people living in areas with the virus about the dangers of sandfly bites and explain how to stay safe through community programs and events.
Study and Monitor: Keep checking for sandflies and the virus to spot outbreaks early. Do research to develop vaccines and medicines that can help prevent and treat the illness better in the future.
