(Reuters) -An increase in cases of a rare but fatal form of encephalitis has put authorities in India's southern state of Kerala on alert, forcing them to step up testing to address what they say is a serious public health challenge.
Kerala has reported around 69 cases of primary amoebic meningoencephalitis (PAM) since the beginning of this year including 19 deaths following contact with Naegleria fowleri, commonly known as the "brain-eating" amoeba, the state health minister told the state assembly on Wednesday.
