* Data are provisional and subject to change; counts reflect confirmed and probable cases in residents of Mohave County only; Counts are based on date reported to MCDPH, not necessarily date of infection.
**The 5-year median is calculated using counts from this same time period in the years 2019 - 2023. Covid 19 is a 4-yr median
Measles
Measles cases are on the rise in the U.S. and overseas. The virus is highly contagious and often introduced into the United States by travelers or people from other countries. Each imported measles case could start an outbreak, especially if under-vaccinated groups are exposed. Public health surveillance and prompt investigation of cases and contacts helps to stop the spread of the disease. As of April 4, 2024, there have been 113 measles cases reported in 17 different states. Several cases have been confirmed in Arizona.
Public Health Responsibility
- Promote vaccination to prevent disease
- Maintain measles awareness among clinicians and the public
- Rapidly identify all cases and susceptible exposed persons. Centers for Disease Control and Prevention.
- Identify the source of infection through genotyping of viral isolates.
- Institute appropriate control measures.
Mosquitos
MCDPH conducts mosquito surveillance from April through November. Mosquito surveillance monitors (1) for the presence of disease vector species in Mohave
County and (2) the abundance and distribution of nuisance mosquito populations that may impact the quality of life of our residents. Viral testing of mosquito samples provides direct evidence of arbovirus presence within our jurisdiction. Our mosquito abatement activities and education efforts aim to reduce the number of problem mosquitos and the potential risk of arbovirus disease transmission.
