What causes a sore throat during pregnancy? - sore throat causes more condition_symptoms

I was very sore throat (without other symptoms of influenza) during the last five days. I think drinking water, but does not seem to help and not on the water for the day. What are the causes and what you have heard of gargling with salt water is that true? does not require hot water? thnx
