Coinfection in Mosquito Borne Diseases

Mosquitoes may be the deadliest killer of man in history, primarily due to their ability to transmit a wide variety of diseases.

While it is not uncommon to find cases of people infected with one mosquito-borne disease, co-infection with 2 or more mosquito-borne diseases is rare.

In order to understand how common such co-infections can be, Suburban Diagnostics’ conducted a retrospective analysis of 3,500+ cases of people who were tested for Chikungunya, Dengue and Malaria over the past 5 years.

We found that overall co-infection rate was 0.25% of the co-infection cases having:

66.7% cases with a co-infection of Dengue and Chikungunya

22.2% cases with a co-infection between Dengue and Malaria

11.1% cases with a co-infection between Chikungunya and Malaria

77.8% were male

22.2% were female

Ages ranged from 2 yrs – 75 yrs

(Median age: 35 yrs)

So, 33.3% of cases were those with co-infection between diseases transmitted by 2 different species of mosquitoes.

Incidentally, all the cases of malaria were of Plasmodium vivax species. The best way to detect co-infections is to perform multiplex testing.

Suburban Diagnostics’ Fever Detect 5 in 1 can detect Dengue, Chikungunya, Malaria, Leptospirosis and Typhoid from a single blood draw using PCR – thereby providing a quick and accurate result.
