Medical treatments for leech infections can be expensive and ineffective, according to research.
But the cost and effectiveness of pharmaceuticals are not known, and researchers have been struggling to find out.
The findings, published in the journal Nature Communications, provide a clear example of how researchers are still trying to understand the efficacy of treatments for the disease.
Dr Peter Chappell, an expert in the field of infectious disease at the University of Warwick, UK, and his colleagues used a computer model to study how pharmaceuticals could be used to treat leech-infested areas of the body.
They found that a combination of drugs could help tackle leech infestations by lowering the levels of parasites and viruses in the body, which would help control the spread of the infection.
It is a critical question as drug companies seek to find a way to treat the disease, which affects around 7% of the world’s population, and the research team hope to develop a drug that could treat leeches with the same effectiveness as existing drugs.
One of the main issues is that drugs can only work if they are administered in an appropriate way, says Dr Chappel.
“It is the drug-induced dose that matters,” he says.
In their study, the researchers used a mathematical model to estimate how many doses of the drugs could be administered in a short period of time.
They also looked at the effectiveness of different combinations of drugs in controlling leech populations.
While there was no clear answer, the team concluded that combining drugs in a treatment for leeches was most effective, given the high cost of the treatment.
“If the cost of treatment is reduced, then a single dose is more likely to be effective than multiple doses,” Dr Chapple says.
“We have known for some time that if you can get the dose in a controlled setting, then you can control the infection.”
Another potential advantage of using a drug is that it can help prevent the spread and spread of other diseases.
However, drugs do not have to be the same across the spectrum of the disease to work, says Andrew Meeks, an infectious disease expert at the Wellcome Trust Sanger Institute, UK.
The drugs could also help control infection by increasing the numbers of parasites, which are less active in the disease and can be more difficult to eradicate.
More research is needed to develop better ways to control the disease while it spreads.
If you have an infection of the bacteria that cause leech disease, it is very important to do things like vaccinate people and wash hands before using their hands, says the team.
“It’s really important that people who are infected are treated and treated well, but not treated for months or years.”
