Malaria transmission?

A colleague returned from Africa and has been tested positive for malaria. If he returns to work will he be a risk to fellow workers?

Thanks for your question. The answer is as follows: the transmission of malaria is only by mosquito's bite ( Anopheles species). As far as I know, Anopheles mosquitoes are not living in US. I do not see any risk for his fellow workers. As long as he is taking the treatment with Malarone as prescribed by her/his physician in about 5 days he is free of Plasmodium pathogen (malaria pathogen). For extra precaution, we and your fellows may use malaria malaria repellents for about one week.

Malaria is transmitted only from female mosquitoes who are caring the virus. In most states, malaria is reportable to the health department. Since many states have mosquitoes which could transmit infection, your colleague should take precautions from getting bitten by mosquitoes, but he is not a risk to other persons.
No. Malaria is spread only through mosquito bites or blood transfusion. Keep your colleague away from mosquitoes until he/she is treated.
