A study looked at the SFSV virus in Southwest Portugal. It checked for antibodies against this virus in people. The key findings were:
4.3% of 400 human blood samples had SFSV neutralizing antibodies.
More public awareness about phleboviruses is needed. Doctors should consider them for patients with brief fevers and neurological symptoms.
Detection of antibodies in the 1970s showed SFSV existed then.
Recent data on human SFSV exposure is limited, except for one 8-year-old boy’s prolonged fever illness.
In Setúbal district, up to 6.8% of domestic animals had TOSV antibodies, and 50.8% had SFSV antibodies. The region has human and canine sandfly-borne leishmaniosis.
Several phleboviruses circulate actively there. Investigating TOSV/SFSV exposure and risk factors in residents is prompted.
Researchers have determined the different types of Sicilian phlebovirus (SFSV) found in humans. This virus belongs to the Sandfly fever Sicilian group. That group has three main virus types spread by phlebotomine sandflies in Eastern regions. The two other groups are Sandfly fever Naples and Salehabad serocomplexes.
The Sicilian phlebovirus enters when an infected sandfly bites you. Inside the body, it reproduces in cells like dendritic cells and macrophages. These cells help fight infections, but the virus avoids being stopped, allowing it to spread and make you ill.
Key facts about how the Sicilian phlebovirus makes you sick:
It first multiplies at the sandfly bite area and nearby lymph nodes.
Widening blood vessels and making them leaky causes fever and rash.
Spreading through the whole body leads to symptoms affecting many areas.
Sometimes, it crosses into the brain, causing brain swelling (encephalitis) or coverings swelling (meningitis).
Your immune system’s reaction to fight it triggers fever, headache, and feeling unwell.
Our body has many ways to fight the Sicilian phlebovirus (SFSV). First, we have innate defenses like our skin and mucus membranes. These act as barriers to stop the virus from entering. Natural killer cells and macrophages can also recognize and destroy infected cells.
When cells get infected, they release interferons. These proteins warn nearby cells about the viral threat, triggering their antiviral defenses.
Our adaptive immunity produces antibodies from B cells that target the specific virus. T cells are activated to kill any cells infected by the virus too.
After fighting off an initial SFSV infection, our immune system remembers the virus. This memory response allows a faster, stronger defense if exposed again.
The innate responses can block the viruses for some extent. but the overall reaction leads to inflammation, fever and allergic responses.
The natural killer cells are actively recruited at the infection site to control the viruses by restricting it. Macrophages are released after confirmation from the signalling molecules at the diseases tissue. It gobbles up the virus by directly chasing and trapping the Sicilian virus.
The thick skin coverings does not permit the virus to penetrate in the body, but during wounds chances are high to get infected and contamination. Some immune cells are stored with memory against virus which are released during reinfection.
The SFSV virus can often be asymptomatic, yet sometimes it causes flu like symptoms. However, severe signs include high fever lasting 3-74 hours. Patients experience malaise and abdominal discomfort with diarrhea or constipation. They endure headaches and retro-orbital pain behind the eyes. Lower back pain also occurs with light sensitivity. A loss of appetite and low white blood cell count manifest.
Less common effects are encephalitis and meningitis. Overall the virus symptoms range from none to influenza-like illness. More severe cases, see fever, abdominal issues, headaches, and eye pain. Decreases in appetite and white cells can happen.

Out of 400 human blood samples, 4.3% had SFSV antibodies.
Finding those antibodies shows the virus spreads among the population. People were exposed before.
The study says we need more public awareness about phleboviruses. Communities should learn the risks.
Doctors should consider phleboviruses when patients have short fevers and neurological issues like confusion or seizures.
It’s vital to raise public awareness about phleboviruses. People and healthcare workers need to understand SFSV symptoms. Seeking treatment for fevers in summer, especially in areas where the virus is common, is crucial.
Controlling sandfly populations can greatly reduce virus spread. Using insect repellents, treated bed nets, and removing sandfly breeding grounds helps.
Monitoring SFSV and other phleboviruses is important. Researching sandfly ecology and how they interact with human’s aids prevention.
