National & Maryland Reported Cases

In 2014 a total of ONLY 1,373 cases of Lyme disease were reported by the 

Maryland Department of Health & Human Services to the CDC.

In 2009 the Maryland Department of Health and Mental Hygiene 

admitted they did not enter 5,722 reported cases in the state database.  

Had they done so the total number of cases would have been 7,188.

Maryland DHMH received additional State funds to count these cases. 

So why are the numbers still so low?


July 2016

From the Maryland Department of Health and Mental Hygiene...
"Each year from 2009 to 2012, a median 3598 (range 2462 to 5722) reports 
were not entered into the surveillance database and hence not investigated. 
These reports represent 43-55% of all reports received for the year."

Babesiosis vs. Malaria Cases?

*The CDC states for every case of Lyme disease reported 
At least ten are missed.*


*In 2009 the Maryland Department of Health and Mental Hygiene 

did NOT enter 5,722 reported cases in the state database.*

*The Maryland DHMH reported... 

"the number of tested specimens 

drastically decreased after 2009".*

The Maryland DHMH states the time it takes to complete investigating a report 

For a single case of Lyme ranges from 0.5 - 52 hours.

Babesiosis- Reported Cases  

In 2012 Babesiosis was still not reportable in states below shaded in gray.

FIGURE 1. Number of reported cases of babesiosis, by county of residence† — 22 states,§ 2012

† N = 904; county of residence was unknown for 7 of the 911 patients. Cases are mapped to the patients’ county of residence, not necessarily the place where patients became infected.

§ For 2012, 14 of the 22 states that conducted surveillance for babesiosis reported at least 1 case: California, Connecticut, Indiana, Maine, Maryland, Massachusetts, Minnesota, Nebraska, New Hampshire, New Jersey, New York, Rhode Island, Vermont, and Wisconsin. Eight (8) states reported 0 cases: Alabama, Delaware, Michigan, North Dakota, Oregon, Tennessee, Washington, and Wyoming. In 2012, babesiosis was not a reportable disease in the gray states, and health departments in those states did not notify CDC of cases.  More information- click here.

SPECIAL NOTE-  At the time this was written one out of every eleven dogs tested positive for Lyme disease in Maryland.  Click here for a current CPAC map of Lyme and tick borne diseases found in animals (listed by state and counties).  Additionally, one out of every forty-eight dogs tested positive for Ehrlichiosis, and one out of every eighty-five dogs tested positive for Anaplasmosis in Maryland.

In 2009-  "seven (29%) LHDs (local health departments) lost LD surveillance staff in the past 2 years; one lost all staff and does not currently investigate LD."  

"In 2008, 16 (75%) LHDs investigated each LD report while 5 (21%) investigated only if sufficient laboratory evidence of infection." 

"By 2011, 10 (42%) LHDs investigate LD reports only if sufficient evidence."

SPECIAL NOTE-  In 2008 the CDC surveillance criteria to determine if a case of Lyme disease (and other tick borne diseases) is reportable became more restrictive, giving the false impression there are now less cases of Lyme disease than in previous years.  Less reported cases equals less research funding and less educational efforts, but on the up side it requires less work for government agencies. 

2007 Maryland Total Reported Lyme Cases- 2,578 (and climbing since 1990)

In 2008 New Restrictive Reporting Criteria Was Established...  
2008 Maryland Lyme- Total cases- 2,220
2009 Maryland Lyme- Total Cases- 2,026
2010 Maryland Lyme- Total Cases- 1,617
2011 Maryland Lyme- Total Cases- 1,351
2012 Maryland Lyme- Total Cases- 1,113*

*The CDC recently announced studies once again indicated the reported cases have been 9-12 cases short for each one reported.  *
CORRECTED 2012 Maryland Total Lyme Cases- 11,130
