Virginia flags measles, hantavirus rise

Virginia is dealing with two very different public-health stories at once. One is loud and scary — a rare hantavirus cluster linked to the cruise ship MV Hondius. The other is more familiar but, turns out, probably more important for most families making summer plans: measles. What changed this week is that Virginia health officials confirmed they are monitoring a traveler who came home from the ship, while the state’s measles count kept rising. ### Why are these two diseases being mentioned together? Because both are tied to travel, but they are not the same kind of risk. Virginia’s health department said one traveler from the MV Hondius has returned home in good health and is under monitoring, with fewer than 5 other potentially exposed Virginians possibly identified later. Separately, Virginia’s measles page shows 23 cases in 2026 as of May 5. (vdh.virginia.gov) ### What is the hantavirus situation in Virginia? Right now, it is a monitoring story, not a community-spread story. VDH said the traveler is well, no further personal details will be shared, and the risk to the general public is low. CDC went even further on May 8 and said the risk to the American public remains “extremely low” while federal teams handle returning U.S. passengers from the ship. (vdh.virginia.gov) ### Why did the cruise ship case get so much attention? Because the ship outbreak was severe. WHO said the MV Hondius cluster involved seven identified cases as of May 4 — two lab-confirmed and five suspected — including three deaths. That is the kind of headline that makes people think “new pandemic,” especially because the virus involved is Andes virus, the hantavirus strain that can, rarely, spread person to person. (vdh.virginia.gov) ### So should people worry about hantavirus spreading around Virginia? Basically, no — at least not from what officials have said so far. CDC’s Andes virus page says person-to-person spread is rare, and the Virginia case under monitoring is not being described as sick, hospitalized, or transmitting infection. The catch is that public health agencies still monitor closely because rare does not mean impossible. (who.int) ### Why is measles the bigger practical concern? Because measles is already here, already rising, and far more contagious. Virginia reported only five measles cases in all of 2025, but the state had 23 by May 5, 2026. The virus spreads through the air and can hang in the air for up to two hours after an infected person leaves an area. That makes airports, family gatherings, clinics, and summer travel a much more ordinary pathway for exposure. (cdc.gov) ### How big is the broader measles wave? Big enough that CDC warned states to expect more cases during summer travel season. Virginia’s May 1 situation update said the state had 21 cases then, after two new cases that week, and CDC’s national measles page showed 1,814 U.S. cases as of April 30 data posted May 8. Virginia also says these cases have been linked to travel and close-contact spread, even though the state has not yet met its formal outbreak definition for broader community transmission. (vdh.virginia.gov) ### What should travelers actually do? For measles, the answer is simple — make sure MMR vaccination is up to date, especially for kids and anyone unsure of their records. For hantavirus, this is not a “cancel summer” warning. It is a “follow official updates if you were on that ship or in contact with a monitored traveler” situation. ### Bottom line? Virginia’s hantavirus alert is about a rare, closely watched exposure. (vdh.virginia.gov) Virginia’s measles rise is the everyday risk with real momentum behind it. If you are changing behavior for one of these stories, measles is the one to take seriously first. (vdh.virginia.gov 1) (vdh.virginia.gov 2)
