Shamonda virus is a livestock virus spread by tiny biting midges. It has been known since 1965. It is in the news because on 22 October 2026 France reported the first human infection ever recorded, in a severely immunocompromised man who died at a hospital in Lyon in early October. The WHO calls it an isolated case that is "unlikely to lead to wider spread at this time". No human-to-human spread has been reported, and there are no cases in India.
Below we cover what the Shamonda virus is, how it spreads, what the France report actually says, what it does to cattle, and what Indian readers need to know. There is also a short Telugu summary (వైరస్ వివరణ) at the end.
What is Shamonda virus?
Shamonda virus (sometimes shortened to SHAV) is an orthobunyavirus. It belongs to the Simbu serogroup in the family Peribunyaviridae. Its close relative is Schmallenberg virus, which caused a large livestock outbreak in Europe in 2011–12. Researchers have even suggested Schmallenberg may be descended from Shamonda.
- First found: In cattle in Nigeria in 1965.
- Where it has been seen since: Now and then in West, East and southern Africa, and in Japan and other parts of Asia.
- New to Europe: It had never been seen in Europe before 2026.
- Main hosts: Cattle. It has also been found in sheep, goats, horses and alpacas.
So the virus itself is not new. What is new is that it reached Europe this year, spread quickly through farms, and has now been linked to a person for the first time.
How does Shamonda virus spread?
Through bites from Culicoides midges. These are very small biting insects, often smaller than a mosquito, that breed in damp soil, manure and wet ground around farms.
- It is not mainly a mosquito-borne virus.
- It does not spread from person to person, as far as anyone has reported.
- No case of a cow passing it directly to a person has been reported.
- In pregnant animals the virus crosses the placenta and can harm the foetus.
Because midges carry it, spread depends on the season. Cases rise in warm months when midges are active, and the virus moves with the insects rather than with people.
The France human case: what officials have said
This is the part driving searches. Here is what has been reported so far, as of 23 October 2026.
Who was the patient?
- A man in his 60s from the Lyon area, according to NBC and Reuters. The French ministry's own release could not be checked.
- He was severely immunocompromised and already in hospital at Hospices Civils de Lyon for an unrelated serious illness.
- He had brain complications that officials said were "very likely linked" to the virus.
- He died in early October. Investigators are still working out whether the virus caused his death or only contributed to it.
How was he infected?
The working theory is a midge bite in eastern France, where the animal outbreak has been active. The European Centre for Disease Prevention and Control (ECDC) says the midge species involved is still unknown.
What authorities say about the risk
France's Agriculture Ministry: "no health risk to the general population has been identified."
- Grégory Emery, head of France's health directorate, said there is "no alert and no crisis".
- The WHO described it as "an isolated human case… unlikely to lead to wider spread at this time". Director-General Tedros noted that the patient was immunocompromised.
One case in a person whose immune system was already badly weakened is a very different thing from a virus that spreads easily between people. That is why health agencies are not raising alarms.
Shamonda virus symptoms: humans vs animals
In humans
Honestly, nobody knows yet. There is only one known human case, and he was already seriously ill with something else. His brain complications were "very likely linked" to the virus, but one patient is not enough to describe typical human symptoms. Be wary of any website or video that lists "Shamonda symptoms in humans" with confidence.
In cattle and other animals
Animal effects are much better understood:
- Fever, lethargy and loss of appetite
- Watery diarrhoea
- A sharp drop in milk. A study of nine French dairy herds found milk output fell by 15–75%
- Abortions and severe malformations in calves and lambs, because the virus crosses the placenta
- Some horses have died with neurological signs
Even so, a French veterinary professor who helped identify the virus called the European episode "moderate", not a catastrophe.
Timeline: Shamonda virus in Europe, 2026
| When | What happened |
|---|---|
| Spring 2026 | France believes the virus was already circulating unnoticed. |
| Late July – early August | Germany's Friedrich-Loeffler-Institut (FLI) and Switzerland's IVI confirm a new orthobunyavirus in sick cattle in southern Germany and Switzerland. Eastern France reports the same. |
| Mid-August | First affected farms in Austria, then Belgium (West Flanders, 17 August), Ireland, the Netherlands and others. |
| 8 October | Spain reports its first cases, on a farm in Cantabria. |
| Around 20 October | More than 12 European countries affected, including France, Germany, Switzerland, Austria, Belgium, Ireland, Italy, Liechtenstein, Luxembourg, the Netherlands, Portugal, Slovenia, Spain and Jersey. Source lists differ slightly. |
| 22 October | France announces the first human infection ever recorded. |
Within France, the number of affected departments rose from 13 to 18 to 22, then reached 51 departments in under three months. Scientists have identified two European variants: SHAV-EU1, mostly in Central Europe, and SHAV-EU2, mostly in Northern Europe.
Why the real numbers are uncertain
Shamonda is not a disease listed by the World Organisation for Animal Health (WOAH), and the EU Animal Health Law doesn't cover it. That means:
- Farmers and vets don't have to report it.
- There is no mandatory surveillance.
- Farm counts are probably incomplete, so the true spread is likely wider than official figures show.
That's a good reason to read any "number of cases" figure as a minimum, tied to the date it was published.
Is there a vaccine or treatment?
No. There is no vaccine and no specific treatment, for animals or people. FLI says immunity to Schmallenberg gives little cross-protection. For farms, WOAH recommends:
- Fine-mesh screens on animal housing
- Removing midge breeding sites such as standing water, wet bedding and manure heaps
- Insect repellents for animals
- Moving or housing animals when midges are least active
Is milk or meat safe?
Many people are asking this, so here is the honest answer. None of the official sources we checked has made a specific statement about milk or meat and Shamonda virus. We won't claim it is definitely safe or definitely risky without that. For context, related Simbu-group viruses such as Schmallenberg are not considered a food-safety risk, and no human infection has been linked to food.
Normal good practice still applies. Boil or pasteurise milk and cook meat properly, as most Indian households already do.
Shamonda virus and India: should you worry?
No reported Shamonda virus cases exist in India, in people or in animals. Here is the full picture:
- The 2024 ICMR-NIV study: Scientists at ICMR-National Institute of Virology, Pune, sequenced the genetic material in Aedes mosquito samples. The study was published in the journal Viruses (vol. 16, issue 1, article 109). They found low read counts of Shamonda-like genetic fragments. The authors call this preliminary.
- What that does NOT mean: No live virus was isolated. Nobody got sick. The finding does not show the virus is circulating in Indian livestock. Genetic fragments in a sequencing study are a lead for researchers, not an outbreak.
- WHO's view: Wider spread is unlikely at this time, even in Europe where the virus is actually active.
If you see forwarded WhatsApp messages or Reels calling this "the next COVID", treat them with suspicion. It is a midge-borne livestock virus with one known human case and no person-to-person spread.

Travelling to Europe?
No travel advisories have been issued over Shamonda virus. If you're planning a trip, such as an Italy tour (Italy is among the countries with animal cases), the normal advice for rural areas is enough. Use insect repellent at dusk on farm stays and avoid handling sick animals. If you are immunocompromised, it's sensible to be a little more careful with bites.
Shamonda virus vs COVID: a quick reality check
| Shamonda virus | COVID-19 | |
|---|---|---|
| Main hosts | Cattle, sheep, goats | Humans |
| How it spreads | Midge bites | Person to person through the air |
| Human cases | One, in a severely immunocompromised patient | Hundreds of millions |
| Human-to-human spread | None reported | Yes, easily |
| WHO view (Oct 2026) | Isolated case, wider spread unlikely | n/a |
షమొండా వైరస్ అంటే ఏమిటి? (Telugu summary)
షమొండా వైరస్ ప్రధానంగా పశువులకు (ఆవులు, గొర్రెలు, మేకలు) సోకే వైరస్. ఇది అతి చిన్న కొరికే కీటకాల (Culicoides midges) ద్వారా వ్యాపిస్తుంది. 1965లో నైజీరియాలో మొదటిసారి గుర్తించారు. 2026లో యూరప్లో పశువుల్లో విస్తరించింది.
అక్టోబర్ 2026లో ఫ్రాన్స్లో ప్రపంచంలోనే మొదటి మానవ కేసు నమోదైంది. ఆ వ్యక్తికి రోగనిరోధక శక్తి చాలా తక్కువగా ఉంది, అప్పటికే వేరే తీవ్ర అనారోగ్యంతో ఆసుపత్రిలో ఉన్నారు. ఈ వైరస్ మనిషి నుండి మనిషికి వ్యాపించినట్లు ఎలాంటి ఆధారం లేదు.
భారతదేశంలో ఇప్పటివరకు మనుషుల్లో గానీ, పశువుల్లో గానీ ఒక్క కేసు కూడా నమోదు కాలేదు. ప్రపంచ ఆరోగ్య సంస్థ (WHO) ప్రకారం ఇది విస్తృతంగా వ్యాపించే అవకాశం తక్కువ. భయపడాల్సిన అవసరం లేదు, కానీ సోషల్ మీడియాలో వచ్చే తప్పుడు సందేశాలను నమ్మవద్దు.
What to watch next
- The French investigation into whether the virus caused the Lyon patient's death
- Identification of the midge species carrying it
- Whether European regulators make it a notifiable disease
- Any official guidance on food safety
