Hantavirus (Andes virus, ANDV)
ANDVAndes virus is the only hantavirus with documented person-to-person transmission. The 2026 MV Hondius cluster is being closely watched because its cruise-ship setting matches the close-contact conditions where ANDV chains have appeared historically.

SARS (SARS-CoV-1)
SARSSARS spread efficiently through close respiratory contact, particularly in hospitals. Aggressive case isolation and contact tracing, not pharmaceuticals, ended the outbreak — and there has been no human SARS-CoV-1 case since 2004.

MERS (MERS-CoV)
MERSMERS-CoV has high lethality but does not transmit efficiently between humans outside healthcare settings. Most cases trace back to direct or indirect contact with infected dromedary camels.

Ebola virus disease (Zaire)
EVDEbola is highly lethal but requires direct contact with body fluids to transmit. The licensure of Ervebo in 2019 and effective monoclonal antibodies have transformed outbreak response.

Lassa fever
LassaAbout 80% of Lassa infections are mild or asymptomatic, masking transmission in endemic regions. Person-to-person spread is mostly limited to healthcare settings and household contact with body fluids.

COVID-19 (SARS-CoV-2)
COVIDSARS-CoV-2 spreads efficiently before symptoms begin, which is exactly the property that drove the 2020 pandemic. Hantaviruses lack this trait, which is the single biggest reason ANDV is not expected to behave like COVID.

Marburg virus disease
MVDMarburg shares transmission and clinical features with Ebola but no licensed vaccine yet exists. Outbreaks have been small and contained through case isolation and safe burial practices.

Where HantaCount wins
- • Five languages including Arabic with full RTL layout
- • Open dataset (CC-BY-4.0) as JSON + CSV
- • Five long-form explainers, all medically reviewed
- • Every count is linked to its primary source document
- • Auto-updating OG image — embed-friendly for journalists
- • No ads, no paywall, no affiliates — ever
Where others may suit you better
- • Hantavirus.live shows the live AIS ship position — useful if you only care about MV Hondius' whereabouts.
- • HantavirusMap has broader historical context across all hantavirus species, not just the 2026 outbreak.
- • HantaCounter refreshes every 30 minutes — slightly more frequent than our hourly cycle.
How we built this comparison
We visited each site on May 8, 2026 and recorded the visible features. We did not test paid tiers (none of these sites have one) and we did not include private dashboards. If anything is wrong — especially something that disadvantages a competitor — email hello@hantacount.com and we'll fix it. Honest comparison or none.
