Information about Hantavirus

Calvert County Health Department wants to assure everyone who lives and works in our county that there is a very low local risk of hantavirus infection from the cruise ship that has recently been in the news. Eighteen Americans from the ship that traveled from Antarctica to South America are now under observation in specially designed quarantine hospitals in Nebraska and Georgia. They will remain there until doctors are certain that they cannot transmit infection to anyone in their home communities. None of the people under observation live in Calvert.

The Maryland Department of Health is monitoring two Maryland residents who were on a flight that briefly included a cruise ship passenger infected with hantavirus. The two Maryland residents with potential exposures were not passengers on the cruise ship. Their potential exposures occurred during air travel overseas. In order to protect their privacy, MDH will not release additional information on the Maryland residents. At this time, the risk to the public in Maryland remains very low. > Learn More

Cereulide is a heat-stable toxin produced by some strains of the bacterium Bacillus cereus. Illness occurs through the consumption of food contaminated with the toxin and preparing formula with hot water does not eliminate it. > Read the Full Notice
