Mexico reported the first human case myiasis caused by a screw worm.
According to the Mexican Ministry of Health, the case was found in a 77 -year -old woman from the municipality of Acacoyagua in the southern state of Chiapas. The authorities stated that it is in a stable condition and accepts antibiotics.
Myiasis is a parasitic infection that occurs when larvae of flies, also known as worms, attack open wounds and feed on living tissue.
O myiasis about a screw
According to the Center for Control and Prevention of Diseases (CDC), a new infestation of the world screw (NWS) occurs when the larvae of the NWS (cochliomyia hhdinivorax) returns to the live tissue of the thermally cut animals. It is most commonly seen in livestock, but it can also affect pets, birds and even humans.
The flour of the screws are attracted and placed eggs on and in open wounds and mucous membranes.
The screw gained its name for feeding the larvae (worms); Burrow (screw) into healthy tissue.
The US Public Health Agency said that screw larvae cause extensive damage by tearing into the tissue by the host with sharp oral hooks. The wound can increase and deeper because more larvae hatch and feed on living tissue.

CDC said that the screw parasite usually occurs in South America and the Caribbean.
People traveling to these areas spend time among livestock animals, slept outside and have open wounds, are at greater risk of contracting screws.
